FIELD OF THE INVENTION
[0002] This invention describes a system which relates to the generation of randomized libraries of ligand-binding protein units derived from proteins containing the so-called C-type lectin like domain (CTLD) of which the carbohydrate recognition domain (CRD) of C-type lectins represents one example of a family of this protein domain.
BACKGROUND OF THE INVENTION
[0003] The C-type lectin-like domain (CTLD) is a protein domain family which has been identified in a number of proteins isolated from many animal species (reviewed in Drickamer and Taylor (1993) and Drickamer (1999)). Initially, the CTLD domain was identified as a domain common to the so-called C-type lectins (calcium-dependent carbohydrate binding proteins) and named "Carbohydrate Recognition Domain" ("CRD"). More recently, it has become evident that this domain is shared among many eukaryotic proteins, of which several do not bind sugar moieties, and hence, the canonical domain has been named as CTLD.
[0004] CTLDs have been reported to bind a wide diversity of compounds, including carbohydrates, lipids, proteins, and even ice [Aspberg et al. (1997), Bettler et al. (1992), Ewart et al. (1998), Graversen et al. (1998), Mizumo et al. (1997), Sano et al. (1998), and Tormo et al. (1999)]. Only one copy of the CTLD is present in some proteins, whereas other proteins contain from two to multiple copies of the domain. In the physiologically functional unit multiplicity in the number of CTLDs is often achieved by assembling single copy protein protomers into larger structures.
[0005] The CTLD consists of approximately 120 amino acid residues and, characteristically, contains two or three intra-chain disulfide bridges. Although the similarity at the amino acid sequence level between CTLDs from different proteins is relatively low, the 3D-structures of a number of CTLDs have been found to be highly conserved, with the structural variability essentially confined to a so-called loop-region, often defined by up to five loops. Several CTLDs contain either one or two binding sites for calcium and most of the side chains which interact with calcium are located in the loop-region.
[0006] On the basis of CTLDs for which 3D structural information is available, it has been inferred that the canonical CTLD is structurally characterised by seven main secondary-structure elements (i.e. five β-strands and two α-helices) sequentially appearing in the order β1; α1; α2; β2; β3; β4; and β5 (FIG. 1, and references given therein). In all CTLDs, for which 3D structures have been determined, the β-strands are arranged in two anti-parallel β-sheets, one composed of β1 and β5, the other composed of β2, β3 and β4. An additional β-strand, β0, often precedes β1 in the sequence and, where present, forms an additional strand integrating with the β1, β5-sheet. Further, two disulfide bridges, one connecting α1 and β5 (CI-CIV, FIG. 1) and one connecting β3 and the polypeptide segment connecting β4 and β5 (CII-CIII, FIG. 1) are invariantly found in all CTLDs characterised so far. In the CTLD 3D-structure, these conserved secondary structure elements form a compact scaffold for a number of loops, which in the present context collectively are referred to as the "loop-region", protruding out from the core. These loops are in the primary structure of the CTLDs organized in two segments, loop segment A, LSA, and loop segment B, LSB. LSA represents the long polypeptide segment connecting β2 and β3 which often lacks regular secondary structure and contains up to four loops. LSB represents the polypeptide segment connecting the β-strands β3 and β4. Residues in LSA, together with single residues in β4, have been shown to specify the Ca2+- and ligand-binding sites of several CTLDs, including that of tetranectin. E.g. muta-genesis studies, involving substitution of single or a few residues, have shown, that changes in binding specificity, Ca2+-sensitivity and/or affinity can be accommodated by CTLD domains [Weis and Drickamer (1996), Chiba et al. (1999), Graversen et al. (2000)].
[0007] As noted above, overall sequence similarities between CTLDs are often limited, as assessed e.g. by aligning a prospective CTLD sequence with the group of structure-characterized CTLDs presented in FIG. 1, using sequence alignment procedures and analysis tools in common use in the field of protein science. In such an alignment, typically 22-30% of the residues of the prospective CTLD will be identical with the corresponding residue in at least one of the structure-characterized CTLDs. The sequence alignment shown in FIG. 1 was strictly elucidated from actual 3D structure data, so the fact that the polypeptide segments of corresponding structural elements of the framework also exhibit strong sequence similarities provide a set of direct sequence-structure signatures, which can readily be inferred from the sequence alignment.
[0008] The implication is that also CTLDs, for which precise 3D structural information is not yet available, can nonetheless be used as frameworks in the construction of new classes of CTLD libraries. The specific additional steps involved in preparing starting materials for the construction of such a new class of CTLD library on the basis of a CTLD, for which no precise 3D structure is available, would be the following: (1) Alignment of the sequence of the new CTLD with the sequence shown in FIG. 1; and (2) Assignment of approximate locations of framework structural elements as guided by the sequence alignment, observing any requirement for minor adjustment of the alignment to ensure precise alignment of the four canonical cysteine residues involved in the formation of the two conserved disulfide bridges (CI-CIV and CII-CIII, in FIG. 1). The main objective of these steps would be to identify the sequence location of the loop-region of the new CTLD, as flanked in the sequence by segments corresponding to the β2-, β3-, and β4-strands. To provide further guidance in this the results of an analysis of the sequences of 29 bona fide CTLDs are given in Table 1 below in the form of typical tetrapeptide sequences, and their consensus sequences, found as parts of CTLD β2- and β3-strands, and the precise location of the β4-strand by position and sequence characteristics as elucidated.

[0010] Of the 29 β2-strands, [0011] 14 were found to conform to the consensus sequence WIGX (SEQ ID NO: 305) (of which 12 were WIGL (SEQ ID NO: 306) sequences, 1 was a WIGI (SEQ ID NO: 307) sequence and 1 was a WIGV (SEQ ID NO: 308) sequence); [0012] 3 were found to conform to the consensus sequence WLGX (SEQ ID NO. 309) (of which 1 was a WLGL (SEQ ID NO: 310) sequence, 1 was a WLGV (SEQ ID NO: 311) sequence and 1 was a WLGA (SEQ ID NO: 312) sequence); [0013] 3 were found to be WMGL (SEQ ID NO: 313) sequences; [0014] 3 were found to conform to the consensus sequence YLXM (SEQ ID NO: 314)(of which 2 were YLSM (SEQ ID NO:315) sequences and 1 was an YLGM (SEQ ID NO: 316) sequence); [0015] 2 were found to conform to the consensus sequence WVGX (SEQ ID NO: 317] (of which 1 was a WVGL (SEQ ID NO: 318] sequence and 1 was a WVGA (SEQ ID NO: 319] sequence); and [0016] the sequences of the remaining 4 β2-strands in the collection were FLGI (SEQ ID NO: 320), FVGL (SEQ ID NO: 321), FIGV (SEQ ID NO: 322) and FLSM {SEQ ID NO: 323) sequences, respectively.
[0017] Therefore, it is concluded that the four-residue β2 consensus sequence ("β2cseq") may be specified as follows: [0018] Residue 1: An aromatic residue, most preferably Trp, less preferably Phe and least preferably Tyr. [0019] Residue 2: An aliphatic or non-polar residue, most preferably Ile, less preferably Leu or Met and least preferably Val. [0020] Residue 3: An aliphatic or hydrophilic residue, most preferably Gly and least preferably Ser. [0021] Residue 4: An aliphatic or non-polar residue, most preferably Leu and less preferably Met, Val or Ile.
[0022] Accordingly the P2 consensus sequence may be summarized as follows: [0023] β2cseq: (W,Y,F)-(I,L,V,M)-(G,S)-(L,M,V,I), [0024] where the underlined residue denotes the most commonly found residue at that sequence position.
[0025] All 29 β3-strands analyzed are initiated with the CysII residue canonical for all known CTLD sequences, and of the 29 β3-strands, [0026] 5 were found to conform to the consensus sequence CVXI (SEQ ID NO: 324) (of which 3 were CVEI (SEQ ID NO: 325) sequences, 1 was a CVTI (SEQ ID NO: 326) sequence and 1 was a CVQI (SEQ ID NO: 327) sequence); [0027] 4 were found to conform to the consensus sequence CVXM (SEQ ID NO: 328) (of which 2 were CVEM (SEQ ID NO: 329) sequences, 1 was a CVVM (SEQ ID NO: 330) sequence and 1 was a CVMM (SEQ ID NO: 331) sequence); [0028] 6 were found to conform to the consensus sequence CVXL (SEQ ID NO: 332) (of which 2 were CVVL (SEQ ID NO: 333) sequences, 2 were a CVSL (SEQ ID NO: 334 sequence, 1 was a CVHL (SEQ ID NO: 335) sequence and 1 was CVAL (SEQ ID NO: 336) sequence); [0029] 3 were found to conform to the consensus sequence CAXL (SEQ ID NO: 337) (of which 2 were CAVL (SEQ ID NO: 338) sequences and 1 was a CASL (SEQ ID NO: 339) sequence); [0030] 2 were found to conform to the consensus sequence CAXF (SEQ ID NO: 340) (of which 1 was 1 CAHF (SEQ ID NO: 341) sequence and 1 was a CAEF (SEQ ID NO: 342) sequence); [0031] 2 were found to conform to the consensus sequence CLXL (SEQ ID NO: 343) (of which 1 was a CLEL (SEQ ID NO: 344) sequence and 1 was a CLGL (SEQ ID NO: 345) sequence); and [0032] the sequences of the remaining 7 β3-strands in the collection were CVYF (SEQ ID NO: 346), CVAQ (SEQ ID NO: 347), CAHV (SEQ ID NO: 348), CAHI (SEQ ID NO:349), CLEI (SEQ ID NO: 350), CIAY (SEQ ID NO: 351), and CMLL (SEQ ID NO: 352) sequences, respectively.
[0033] Therefore, it is concluded that the four-residue β3 consensus sequence ("(33cseq") may be specified as follows: [0034] Residue 1: Cys, being the canonical CysII residue of CTLDs [0035] Residue 2: An aliphatic or non-polar residue, most preferably Val, less preferably Ala or Leu and least preferably Ile or Met [0036] Residue 3: Most commonly an aliphatic or charged residue, which most preferably is Glu [0037] Residue 4: Most commonly an aliphatic, non-polar, or aromatic residue, most preferably Leu or Ile, less preferably Met or Phe and least preferably Tyr or Val.
[0038] Accordingly the β3 consensus sequence may be summarized as follows: [0039] β3cseq: (C)-(V,A,L,I,M)-(E,X)-(L,I,M,F,Y,V), [0040] where the underlined residue denotes the most commonly found residue at that sequence position.
[0041] It is observed from the known 3D-structures of CTLDs (FIG. 1), that the β4-strands most often are comprised by five residues located in the primary structure at positions -6 to -2 relative to the canonical CysIII residue of all known CTLDs, and less often are comprised by four residues located at positions -5 to -2 relative to the canonical CysIII residue of all known CTLDs. The residue located at position -3, relative to CysIII, is involved in co-ordination of the site 2 calcium ion in CTLDs housing this site, and this notion is reflected in the observation, that of the 29 CTLD sequences analyzed in Table 1, 27 have an Asp-residue or an Asn-residue at this position, whereas 2 CTLDs have a Ser at this position. From the known CTLD 3D-structures it is also noted, that the residue located at position -5, relative to the CysIII residue, is involved in the formation of the hydrophobic core of the CTLD scaffold. This notion is reflected in the observation, that of the 29 CTLD sequences analyzed 25 have a Trp-residue, 3 have a Leu-residue, and 1 an Ala-residue at this position. 18 of the 29 CTLD sequences analyzed have an Asn-residue at position -4. Further, 19 of the 29 β4-strand segments are preceded by a Gly residue.
[0042] Of the 29 central three residue motifs located at positions -5, -4 and -3 relative to the canonical CysIII residue in the β4-strand: [0043] 22 were of the sequence WXD (18 were WND, 2 were WKD, 1 was WFD and 1 was WWD), [0044] 2 were of the sequence WXN (1 was WVN and 1 was WSN), [0045] and the remaining 5 motifs (WRS, LDD, LDN, LKS and ALD) were each represented once in the analysis.
[0046] It has now been found that each member of the family of CTLD domains represents an attractive opportunity for the construction of new protein libraries from which members with affinity for new ligand targets can be identified and isolated using screening or selection methods. Such libraries may be constructed by combining a CTLD framework structure in which the CTLD's loop-region is partially or completely replaced with one or more randomized polypeptide segments.
[0047] One such system, where the protein used as scaffold is tetranectin or the CTLD domain of tetranectin, is envisaged as a system of particular interest, not least because the stability of the trimeric complex of tetranectin protomers is very high (International Patent Application Publication No. WO 98/56906 A2).
[0048] Tetranectin is a trimeric glycoprotein [Holtet et al. (1997), Nielsen et al. (1997)], which has been isolated from human plasma and found to be present in the extracellular matrix in certain tissues. Tetranectin is known to bind calcium, complex polysaccharides, plasminogen, fibrinogen/fibrin, and apolipoprotein (a). The interaction with plasminogen and apolipoprotein (a) is mediated by the so-called kringle 4 protein domain therein. This interaction is known to be sensitive to calcium and to derivatives of the amino acid lysine [Graversen et al. (1998)].
[0049] A human tetranectin gene has been characterised, and both human and murine tetranectin cDNA clones have been isolated. Both the human and the murine mature protein comprise 181 amino acid residues (FIG. 2). The 3D-structures of full length recombinant human tetranectin and of the isolated tetranectin CTLD have been determined independently in two separate studies [Nielsen et al. (1997) and Kastrup et al. (1998)]. Tetranectin is a two- or possibly three-domain protein, i.e. the main part of the polypeptide chain comprises the CTLD (amino acid residues Gly53 to Val181), whereas the region Leu26 to Lys52 encodes an alpha-helix governing trimerisation of the protein via the formation of a homotrimeric parallel coiled coil. The polypeptide segment Glu1 to Glu25 contains the binding site for complex polysaccharides (Lys6 to Lys15) [Lorentsen et al. (2000)] and appears to contribute to stabilization of the trimeric structure [Holtet et al. (1997)]. The two amino acid residues Lys148 and Glu150, localized in loop 4, and Asp165 (localized in β4) have been shown to be of critical importance for plasminogen kringle 4 binding, whereas the residues Ile140 (in loop 3) and Lys166 and Arg167 (in β4) have been shown to be of some importance [Graversen et al. (1998)]. Substitution of Thr149 (in loop 4) with an aromatic residue has been shown to significantly increase affinity of tetranectin to kringle 4 and to increase affinity for plasminogen kringle 2 to a level comparable to the affinity of wild type tetranectin for kringle 4 [Graversen et al. (2000)].
OBJECT OF THE INVENTION
[0050] The object of the invention is to provide a new practicable method for the generation of useful protein products endowed with binding sites able to bind substance of interest with high affinity and specificity.
[0051] The invention describes one way in which such new and useful protein products may advantageously be obtained by applying standard combinatorial protein chemistry methods, commonly used in the recombinant antibody field, to generate randomized combinatorial libraries of protein modules, in which each member contains an essentially common core structure similar to that of a CTLD.
[0052] The variation of binding site configuration among naturally occurring CTLDs shows that their common core structure can accommodate many essentially different configurations of the ligand binding site. CTLDs are therefore particularly well suited to serve as a basis for constructing such new and useful protein products with desired binding properties.
[0053] In terms of practical application, the new artificial CTLD protein products can be employed in applications in which antibody products are presently used as key reagents in technical biochemical assay systems or medical in vitro or in vivo diagnostic assay systems or as active components in therapeutic compositions.
[0054] In terms of use as components of in vitro assay systems, the artificial CTLD protein products are preferable to antibody derivatives as each binding site in the new protein product is harboured in a single structurally autonomous protein domain. CTLD domains are resistant to proteolysis, and neither stability nor access to the ligand-binding site is compromised by the attachment of other protein domains to the N- or C-terminus of the CTLD. Accordingly, the CTLD binding module may readily be utilized as a building block for the construction of modular molecular assemblies, e.g. harbouring multiple CLTDs of identical or nonidentical specificity in addition to appropriate reporter modules like peroxidases, phosphatases or any other signal-mediating moiety.
[0055] In terms of in vivo use as essential component of compositions to be used for in vivo diagnostic or therapeutic purposes, artificial CTLD protein products constructed on the basis of human CTLDs are virtually identical to the corresponding natural CTLD protein already present in the body, and are therefore expected to elicit minimal immunological response in the patient. Single CTLDs are about half the mass of the smallest functional antibody derivative, the single-chain Fv derivative, and this small size may in some applications be advantageous as it may provide better tissue penetration and distribution, as well as a shorter half-life in circulation. Multivalent formats of CTLD proteins, e.g. corresponding to the complete tetranectin trimer or the further multimerized collectins, like e.g. mannose binding protein, provide increased binding capacity and avidity and longer circulation half-life.
[0056] One particular advantage of the preferred embodiment of the invention, arises from the fact that mammalian tetranectins, as exemplified by murine and human tetranectin, are of essentially identical structure. This conservation among species is of great practical importance as it allows straightforward swapping of polypeptide segments defining ligand-binding specificity between e.g. murine and human tetranectin derivatives. The option of facile swapping of species genetic background between tetranectin derivatives is in marked contrast to the well-known complications of effecting the "humanisation" of murine antibody derivatives.
[0057] Further advantages of the invention are:
[0058] The availability of a general and simple procedure for reliable conversion of an initially selected protein derivative into a final protein product, which without further reformatting may be produced in bacteria (e.g. Escherichia coli) both in small and in large scale (International Patent Application Publication No. WO 94/18227 A2).
[0059] The option of including several identical or non-identical binding sites in the same functional protein unit by simple and general means, thereby enabling the exploitation even of weak affinities by means of avidity in the interaction, or the construction of bi- or heterofunctional molecular assemblies (International Patent Application Publication No. WO 98/56906 A2).
[0060] The possibility of modulating binding by addition or removal of divalent metal ions (e.g. calcium ions) in combinational libraries with one or more preserved metal binding site(s) in the CTLDs.
SUMMARY OF THE INVENTION
[0061] The present invention provides a great number of novel and useful proteins each being a protein having the scaffold structure of C-type lectin-like domains (CTLD), said protein comprising a variant of a model CTLD wherein the α-helices and β-strands and connecting segments are conserved to such a degree that the scaffold structure of the CTLD is substantially maintained, while the loop region is altered by amino acid substitution, deletion, insertion or any combination thereof, with the proviso that said protein is not any of the known CTLD loop derivatives of C-type lectin-like proteins or C-type lectins listed in the following Table 2.

[0062] Normally the model CTLD is defined by having a 3D structure that conforms to the secondary-structure arrangement illustrated in FIG. 1 characterized by the following main secondary structure elements: [0063] five β-strands and two α-helices sequentially appearing in the order β1, α1, α2, β2, β3, β4, and β5, the β-strands being arranged in two anti-parallel β-sheets, one composed of β1 and β5, the other composed of β2, β3 and β4, [0064] at least two disulfide bridges, one connecting al and β5 and one connecting β3 and the polypeptide segment connecting β4 and β5, [0065] a loop region consisting of two polypeptide segments, loop segment A (LSA) connecting β2 and β3 and comprising typically 15-70 or, less typically, 5-14 amino acid residues, and loop segment B (LSB) connecting β3 and β4 and comprising typically 5-12 or less typically, 2-4 amino acid residues.
[0066] However, also a CTLD, for which no precise 3D structure is available, can be used as a model CTLD, such CTLD being defined by showing sequence similarity to a previously recognised member of the CTLD family as expressed by an amino acid sequence identity of at least 22%, preferably at least 25% and more preferably at least 30%, and by containing the cysteine residues necessary for establishing the conserved two-disulfide bridge topology (i.e. CysI, CysII, CysIII and CysIV). The loop region, consisting of the loop segments LSA and LSB, and its flanking β-strand structural elements can then be identified by inspection of the sequence alignment with the collection of CTLDs shown in FIG. 1, which provides identification of the sequence locations of the β2- and β3-strands with the further corroboration provided by comparison of these sequences with the four-residue consensus sequences, β2cseq and β3cseq, and the β4 strand segment located typically at positions -6 to -2 and less typically at positions -5 to -2 relative to the conserved CysIII residue and with the characteristic residues at positions -5 and -3 as elucidated from Table 1 and deducted above under BACKGROUND OF THE INVENTION.
[0067] The same considerations apply for determining whether in a model CTLD the α-helices and β-strands and connecting segments are conserved to such a degree that the scaffold structure of the CTLD is substantially maintained.
[0068] It may be desirable that up to 10, preferably up to 4, and more preferably 1 or 2, amino acid residues are substituted, deleted or inserted in the α-helices and/or β-strands and/or connecting segments of the model CTLD. In particular, changes of up to 4 residues may be made in the β-strands of the model CTLD as a consequence of the introduction of recognition sites for one or more restriction endonucleases in the nucleotide sequence encoding the CTLD to facilitate the excision of part or all of the loop region and the insertion of an altered amino acid sequence instead while the scaffold structure of the CTLD is substantially maintained.
[0069] Of particular interest are proteins wherein the model CTLD is that of a tetranectin. Well known tetranectins the CTLDs of which can be used as model CTLDs are human tetranectin and murine tetranectin. The proteins according to the invention thus comprise variants of such model CTLDs.
[0070] The proteins according to the invention may comprise N-terminal and/or C-terminal extensions of the CTLD variant, and such extensions may for example contain effector, enzyme, further binding and/or multimerising functions. In particular, said extension may be the non-CTLD-portions of a native C-type lectin-like protein or C-type lectin or a "soluble" variant thereof lacking a functional transmembrane domain.
[0071] The proteins according to the invention may also be multimers of a moiety comprising the CTLD variant, e.g. derivatives of the native tetranectin trimer.
[0072] In a preferred aspect the present invention provides a combinatorial library of proteins having the scaffold structure of C-type lectin-like domains (CTLD), said proteins comprising variants of a model CTLD wherein the α-helices and β-strands are conserved to such a degree that the scaffold structure of the CTLD is substantially maintained, while the loop region or parts of the loop region of the CTLD is randomized with respect to amino acid sequence and/or number of amino acid residues.
[0073] The proteins making up such a library comprise variants of model CTLDs defined as for the above proteins according to the invention, and the variants may include the changes stated for those proteins.
[0074] In particular, the combinatorial library according to the invention may consist of proteins wherein the model CTLD is that of a tetranectin, e.g. that of human tetranectin or that of murine tetranectin.
[0075] The combinatorial library according to the invention may consist of proteins comprising N-terminal and/or C-terminal extensions of the CTLD variant, and such extensions may for example contain effector, enzyme, further binding and/or multimerising functions. In particular, said extensions may be the non-CTLD-portions of a native C-type lectin-like protein or C-type lectin or a "soluble" variant thereof lacking a functional transmembrane domain.
[0076] The combinatorial library according to the invention may also consist of proteins that are multimers of a moiety comprising the CTLD variant, e.g. derivatives of the native tetranectin trimer.
[0077] The present invention also provides derivatives of a native tetranectin wherein up to 10, preferably up to 4, and more preferably 1 or 2, amino acid residues are substituted, deleted or inserted in the α-helices and/or β-strands and/or connecting segments of its CTLD as well as nucleic acids encoding such derivatives. Specific derivatives appear from SEQ ID Nos: 02, 04, 09, 11, 13, 15, 29, 31, 36, and 38; and nucleic acids comprising nucleotide inserts encoding specific tetranectin derivatives appear from SEQ ID Nos: 12, 14, 35, and 37.
[0078] The invention comprises a method of constructing a tetranectin derivative adapted for the preparation of a combinatorial library according to the invention, wherein the nucleic acid encoding the tetranectin derivative has been modified to generate endonuclease restriction sites within nucleic acid segments encoding β2, β3 or β4, or up to 30 nucleotides upstream or downstream in the sequence from any nucleotide which belongs to a nucleic acid segment encoding β2, β3 or β4.
[0079] The invention also comprises the use of a nucleotide sequence encoding a tetranectin, or a derivative thereof wherein the scaffold structure of its CTLD is substantially maintained, for preparing a library of nucleotide sequences encoding related proteins by randomising part or all of the nucleic acid sequence encoding the loop region of its CTLD.
[0080] Further, the present invention provides nucleic acid comprising any nucleotide sequence encoding a protein according to the invention.
[0081] In particular, the invention provides a library of nucleic acids encoding proteins of a combinatorial library according to the invention, in which the members of the ensemble of nucleic acids, that collectively constitute said library of nucleic acids, are able to be expressed in a display system, which provides for a logical, physical or chemical link between entities displaying phenotypes representing properties of the displayed expression products and their corresponding genotypes.
[0082] In such a library the display system may be selected from [0083] (I) a phage display system such as [0084] (1) a filamentous phage fd in which the library of nucleic acids is inserted into [0085] (a) a phagemid vector, [0086] (b) the viral genome of a phage [0087] (c) purified viral nucleic acid in purified single- or double-stranded form, or [0088] (2) a phage lambda in which the library is inserted into [0089] (a) purified phage lambda DNA, or [0090] (b) the nucleic acid in lambda phage particles; or [0091] (II) a viral display system in which the library of nucleic acids is inserted into the viral nucleic acid of a eukaryotic virus such as baculovirus; or [0092] (III) a cell-based display system in which the library of nucleic acids is inserted into, or adjoined to, a nucleic acid carrier able to integrate either into the host genome or into an extrachromosomal element able to maintain and express itself within the cell and suitable for cell-surface display on the surface of [0093] (a) bacterial cells, [0094] (b) yeast cells, or [0095] (c) mammalian cells; or [0096] (IV) a nucleic acid entity suitable for ribosome linked display into which the library of nucleic acid is inserted; or [0097] (V) a plasmid suitable for plasmid linked display into which the library of nucleic acid is inserted.
[0098] A well-known and useful display system is the "Recombinant Phage Antibody System" with the phagemid vector "pCANTAB 5E" supplied by Amersham Pharmacia Biotech (code no. 27-9401-01).
[0099] Further, the present invention provides a method of preparing a protein according to the invention, wherein the protein comprises at least one or more, identical or not identical, CTLD domains with novel loop-region sequences which has (have) been isolated from one or more CTLD libraries by screening or selection. At least one such CTLD domain may have been further modified by mutagenesis; and the protein containing at least one CTLD domain may have been assembled from two or more components by chemical or enzymatic coupling or crosslinking.
[0100] Also, the present invention provides a method of preparing a combinatorial library according to the invention comprising the following steps: [0101] 1) inserting nucleic acid encoding a protein comprising a model CTLD into a suitable vector, [0102] 2) if necessary, introducing restriction endonuclease recognition sites by site directed mutagenesis, said recognition sites being properly located in the sequence at or close to the ends of the sequence encoding the loop region of the CTLD or part thereof, [0103] 3) excising the DNA fragment encoding the loop region or part thereof by use of the proper restriction endonucleases, [0104] 4) ligating mixtures of DNA fragments into the restricted vector, and [0105] 5) inducing the vector to express randomized proteins having the scaffold structure of CTLDs in a suitable medium.
[0106] In a further aspect, the present invention provides a method of screening a combinatorial library according to the invention for binding to a specific target which comprises the following steps: [0107] 1) expressing a nucleic acids library to display the library of proteins in the display system; [0108] 2) contacting the collection of entities displayed with a suitably tagged target substance for which isolation of a CTLD-derived exhibiting affinity for said target substance is desired; [0109] 3) harvesting subpopulations of the entities displayed that exhibit affinity for said target substance by means of affinity-based selective extractions, utilizing the tag to which said target substance is conjugated or physically attached or adhering to as a vehicle or means of affinity purification, a procedure commonly referred to in the field as "affinity panning", followed by re-amplification of the sub-library; [0110] 4) isolating progressively better binders by repeated rounds of panning and re-amplification until a suitably small number of good candidate binders is obtained; and, [0111] 5) if desired, isolating each of the good candidates as an individual clone and subjecting it to ordinary functional and structural characterisation in preparation for final selection of one or more preferred product clones.
[0112] In a still further aspect, the present invention provides a method of reformatting a protein according to the invention or selected from a combinatorial library according to the invention and containing a CTLD variant exhibiting desired binding properties, in a desired alternative species-compatible framework by excising the nucleic acid fragment encoding the loop region-substituting polypeptide and any required single framework mutations from the nucleic acid encoding said protein using PCR technology, site directed mutagenesis or restriction enzyme digestion and inserting said nucleic acid fragment into the appropriate location(s) in a display--or protein expression vector that harbours a nucleic acid sequence encoding the desired alternative CTLD framework.

DETAILED DESCRIPTION OF THE INVENTION
[0165] I. Definitions
[0166] The terms "C-type lectin-like protein" and "C-type lectin" are used to refer to any protein present in, or encoded in the genomes of, any eukaryotic species, which protein contains one or more CTLDs or one or more domains belonging to a subgroup of CTLDs, the CRDs, which bind carbohydrate ligands. The definition specifically includes membrane attached C-type lectin-like proteins and C-type lectins, "soluble" C-type lectin-like proteins and C-type lectins lacking a functional transmembrane domain and variant C-type lectin-like proteins and C-type lectins in which one or more amino acid residues have been altered in vivo by glycosylation or any other post-synthetic modification, as well as any product that is obtained by chemical modification of C-type lectin-like proteins and C-type lectins.
[0167] In the claims and throughout the specification certain alterations may be defined with reference to amino acid residue numbers of a CTLD domain or a CTLD-containing protein. The amino acid numbering starts at the first N-terminal amino acid of the CTLD or the native or artificial CTLD-containing protein product, as the case may be, which shall in each case be indicated by unambiguous external literature reference or internal reference to a figure contained herein within the textual context.
[0168] The terms "amino acid", "amino acids" and "amino acid residues" refer to all naturally occurring L-α-amino acids. This definition is meant to include norleucine, ornithine, and homocysteine. The amino acids are identified by either the single-letter or three-letter designations:
TABLE-US-00003 Asp D aspartic acid Ile I isoleucine Thr T threonine Leu L leucine Ser S serine Tyr Y tyrosine Glu E glutamic acid Phe F phenylalanine Pro P proline His H histidine Gly G glycine Lys K lysine Ala A alanine Arg R arginine Cys C cysteine Trp W tryptophan Val V valine Gln Q glutamine Met M methionine Asn N asparagine Nle J norleucine Orn O ornithine Hcy U homocysteine Xxx X any L-α-amino acid.
[0169] The naturally occurring L-α-amino acids may be classified according to the chemical composition and properties of their side chains. They are broadly classified into two groups, charged and uncharged. Each of these groups is divided into subgroups to classify the amino acids more accurately: [0170] A. Charged Amino Acids [0171] Acidic Residues: Asp, Glu [0172] Basic Residues: Lys, Arg, His, Orn [0173] B. Uncharged Amino Acids [0174] Hydrophilic Residues: Ser, Thr, Asn, Gln [0175] Aliphatic Residues: Gly, Ala, Val, Leu, Ile, Nle [0176] Non-polar Residues: Cys, Met, Pro, Hcy [0177] Aromatic Residues: Phe, Tyr, Trp
[0178] The terms "amino acid alteration" and "alteration" refer to amino acid substitutions, deletions or insertions or any combinations thereof in a CTLD amino acid sequence. In the CTLD variants of the present invention such alteration is at a site or sites of a CTLD amino acid sequence. Substitutional variants herein are those that have at least one amino acid residue in a native CTLD sequence removed and a different amino acid inserted in its place at the same position. The substitutions may be single, where only one amino acid in the molecule has been substituted, or they may be multiple, where two or more amino acids have been substituted in the same molecule.
[0179] The designation of the substitution variants herein consists of a letter followed by a number followed by a letter. The first (leftmost) letter designates the amino acid in the native (unaltered) CTLD or CTLD-containing protein. The number refers to the amino acid position where the amino acid substitution is being made, and the second (righthand) letter designates the amino acid that is used to replace the native amino acid. As mentioned above, the numbering starts with "1" designating the N-terminal amino acid sequence of the CTLD or the CTLD-containing protein, as the case may be. Multiple alterations are separated by a comma (,) in the notation for ease of reading them.
[0180] The terms "nucleic acid molecule encoding", "DNA sequence encoding", and "DNA encoding" refer to the order or sequence of deoxyribonucleotides along a strand of deoxyribonucleic acid. The order of these deoxyribonucleotides determines the order of amino acids along the polypeptide chain. The DNA sequence thus encodes the amino acid sequence.
[0181] The terms "mutationally randomized sequence", "randomized polypeptide segment", "randomized amino acid sequence", "randomized oligonucleotide" and "mutationally randomized sequence", as well as any similar terms used in any context to refer to randomized sequences, polypeptides or nucleic acids, refer to ensembles of polypeptide or nucleic acid sequences or segments, in which the amino acid residue or nucleotide at one or more sequence positions may differ between different members of the ensemble of polypeptides or nucleic acids, such that the amino acid residue or nucleotide occurring at each such sequence position may belong to a set of amino acid residues or nucleotides that may include all possible amino acid residues or nucleotides or any restricted subset thereof. Said terms are often used to refer to ensembles in which the number of amino acid residues or nucleotides is the same for each member of the ensemble, but may also be used to refer to such ensembles in which the number of amino acid residues or nucleotides in each member of the ensemble may be any integer number within an appropriate range of integer numbers.
[0182] II. Construction and Utility of Combinatorial CTLD Libraries
[0183] Several systems displaying phenotype, in terms of putative ligand binding modules or modules with putative enzymatic activity, have been described. These include: phage display (e.g. the filamentous phage fd [Dunn (1996), Griffiths amd Duncan (1998), Marks et al. (1992)], phage lambda [Mikawa et al. (1996)]), display on eukarotic virus (e.g. baculovirus [Ernst et al. (2000)]), cell display (e.g. display on bacterial cells [Benhar et al. (2000)], yeast cells [Boder and Wittrup (1997)], and mammalian cells [Whitehorn et al. (1995)], ribosome linked display [Schaffitzel et al. (1999)], and plasmid linked display [Gates et al. (1996)].
[0184] The most commonly used method for phenotype display and linking this to genotype is by phage display. This is accomplished by insertion of the reading frame encoding the scaffold protein or protein of interest into an intra-domain segment of a surface exposed phage protein. The filamentous phage fd (e.g. M13) has proven most useful for this purpose. Polypeptides, protein domains, or proteins are the most frequently inserted either between the "export" signal and domain 1 of the fd gene III protein or into a so-called hinge region between domain 2 and domain 3 of the fd-phage gene III protein. Human antibodies are the most frequently used proteins for the isolation of new binding units, but other proteins and domains have also been used (e.g. human growth hormone [Bass et al. (1990)], alkaline phosphatase [McCafferty et al. (1991)], β-lactamase inhibitory protein [Huang et al. (2000)], and cytotoxic T lymphocyte-associated antigen 4 [Hufton et al. (2000)]. The antibodies are often expressed and presented as scFv or Fab fusion proteins. Three strategies have been employed. Either a specific antibody is used as a scaffold for generating a library of mutationally randomized sequences within the antigen binding clefts [e.g. Fuji et al. (1998)] or libraries representing large ensembles of human antibody encoding genes from non-immunised hosts [e.g. Nissim et al. (1994)] or from immunised hosts [e.g. Cyr and Hudspeth (2000)] are cloned into the fd phage vector.
[0185] The general procedure for accomplishing the generation of a display system for the generation of CTLD libraries comprise essentially [0186] (1) identification of the location of the loop-region, by referring to the 3D structure of the CTLD of choice, if such information is available, or, if not, identification of the sequence locations of the β2-, β3- and β4 strands by sequence alignment with the sequences shown in FIG. 1, as aided by the further corroboration by identification of sequence elements corresponding to the β2 and β3 consensus sequence elements and β4-strand characteristics, also disclosed above; [0187] (2) subcloning of a nucleic acid fragment encoding the CTLD of choice in a protein display vector system with or without prior insertion of endonuclease restriction sites close to the sequences encoding β2, β3 and β4; and [0188] (3) substituting the nucleic acid fragment encoding some or all of the loop-region of the CTLD of choice with randomly selected members of an ensemble consisting of a multitude of nucleic acid fragments which after insertion into the nucleic acid context encoding the receiving framework will substitute the nucleic acid fragment encoding the original loop-region polypeptide fragments with randomly selected nucleic acid fragments. Each of the cloned nucleic acid fragments, encoding a new polypeptide replacing an original loop-segment or the entire loop-region, will be decoded in the reading frame determined within its new sequence context.
[0189] Nucleic acid fragments may be inserted in specific locations into receiving nucleic acids by any common method of molecular cloning of nucleic acids, such as by appropriately designed PCR manipulations in which chemically synthesized nucleic acids are copy-edited into the receiving nucleic acid, in which case no endonuclease restriction sites are required for insertion. Alternatively, the insertion/excision of nucleic acid fragments may be facilitated by engineering appropriate combinations of endonuclease restriction sites into the target nucleic acid into which suitably designed oligonucleotide fragments may be inserted using standard methods of molecular cloning of nucleic acids.
[0190] It will be apparent that interesting CTLD variants isolated from CTLD libraries in which restriction endonuclease sites have been inserted for convenience may contain mutated or additional amino acid residues that neither correspond to residues present in the original CTLD nor are important for maintaining the interesting new affinity of the CTLD variant. If desirable, e.g. in case the product needs to be rendered as non-immunogenic as possible, such residues may be altered or removed by back-mutation or deletion in the specific clone, as appropriate.
[0191] The ensemble consisting of a multitude of nucleic acid fragments may be obtained by ordinary methods for chemical synthesis of nucleic acids by directing the step-wise synthesis to add pre-defined combinations of pure nucleotide monomers or a mixture of any combination of nucleotide monomers at each step in the chemical synthesis of the nucleic acid fragment. In this way it is possible to generate any level of sequence degeneracy, from one unique nucleic acid sequence to the most complex mixture, which will represent a complete or incomplete representation of maximum number unique sequences of 4N, where N is the number of nucleotides in the sequence.
[0192] Complex ensembles consisting of multitudes of nucleic acid fragments may, alternatively, be prepared by generating mixtures of nucleic acid fragments by chemical, physical or enzymatic fragmentation of high-molecular mass nucleic acid compositions like, e.g., genomic nucleic acids extracted from any organism. To render such mixtures of nucleic acid fragments useful in the generation of molecular ensembles, as described here, the crude mixtures of fragments, obtained in the initial cleavage step, would typically be size-fractionated to obtain fragments of an approximate molecular mass range which would then typically be adjoined to a suitable pair of linker nucleic acids, designed to facilitate insertion of the linker-embedded mixtures of size-restricted oligonucleotide fragments into the receiving nucleic acid vector.
[0193] To facilitate the construction of combinatorial CTLD libraries in tetranectin, the model CTLD of the preferred embodiment of the invention, suitable restriction sites located in the vicinity of the nucleic acid sequences encoding β2, β3 and β4 in both human and murine tetranectin were designed with minimal perturbation of the polypeptide sequence encoded by the altered sequences. It was found possible to establish a design strategy, as detailed below, by which identical endonuclease restriction sites could be introduced at corresponding locations in the two sequences, allowing interesting loop-region variants to be readily excised from a recombinant murine CTLD and inserted correctly into the CTLD framework of human tetranectin or vice versa.
[0194] Analysis of the nucleotide sequence encoding the mature form of human tetranectin reveals (FIG. 2) that a recognition site for the restriction endonuclease Bgl II is found at position 326 to 331 (AGATCT), involving the encoded residues Glu109, Ile110, and Trp111 of β2, and that a recognition site for the restriction endonuclease Kas I is found at position 382 to 387 (GGCGCC), involving the encoded amino acid residues Gly128 and Ala129 (located C-terminally in loop 2).
[0195] Mutation, by site directed mutagenesis, of G513 to A and of C514 to T in the nucleotide sequence encoding human tetranectin would introduce a Mun I restriction endonuclease recognition site therein, located at position 511 to 516, and mutation of G513 to A in the nucleotide sequence encoding murine tetranectin would introduce a Mun I restriction endonuclease site therein at a position corresponding to the Mun I site in human tetranectin, without affecting the amino acid sequence of either of the encoded protomers. Mutation, by site directed mutagenesis, of C327 to G and of G386 to C in the nucleotide sequence encoding murine tetranectin would introduce a Bgl II and a Kas I restriction endonuclease recognition site, respectively, therein. Additionally, A325 in the nucleotide sequence encoding murine tetranectin is mutagenized to a G. These three mutations would affect the encoded amino acid sequence by substitution of Asn109 to Glu and Gly129 to Ala, respectively. Now, the restriction endonuclease Kas I is known to exhibit marked site preference and cleaves only slowly the tetranectin coding region. Therefore, a recognition site for another restriction endonuclease substituting the Kas I site is preferred (e.g. the recognition site for the restriction endonuclease Kpn I, recognition sequence GGTACC). The nucleotide and amino acid sequences of the resulting tetranectin derivatives, human tetranectin lectin (htlec) and murine tetranectin lectin (mtlec) are shown in FIG. 3. The nucleotide sequences encoding the htlec and mtlec protomers may readily be subcloned into devices enabling protein display of the linked nucleotide sequence (e.g. phagemid vectors) and into plasmids designed for heterologous expression of protein [e.g. pT7H6, Christensen et al. (1991)]. Other derivatives encoding only the mutated CTLDs of either htlec or mtlec (htCTLD and mtCTLD, respectively) have also been constructed and subcloned into phagemid vectors and expression plasmids, and the nucleotide and amino acid sequences of these CTLD derivatives are shown in FIG. 4.
[0196] The presence of a common set of recognition sites for the restriction endonucleases Bgl II, Kas I or Kpn I, and Mun I in the ensemble of tetranectin and CTLD derivatives allows for the generation of protein libraries with randomized amino acid sequence in one or more of the loops and at single residue positions in β4 comprising the lectin ligand binding region by ligation of randomized oligonucleotides into properly restricted phagemid vectors encoding htlec, mtlec, htCTLD, or mtCTLD derivatives.
[0197] After rounds of selection on specific targets (e.g. eukaryotic cells, virus, bacteria, specific proteins, polysaccharides, other polymers, organic compounds etc.) DNA may be isolated from the specific phages, and the nucleotide sequence of the segments encoding the ligand-binding region determined, excised from the phagemid DNA and transferred to the appropriate derivative expression vector for heterologous production of the desired product. Heterologous production in a prokaryote may be preferred because an efficient protocol for the isolation and refolding of tetranectin and derivatives has been reported (International Patent Application Publication WO 94/18227 A2).
[0198] A particular advantage gained by implementing the technology of the invention, using tetranectin as the scaffold structure, is that the structures of the murine and human tetranectin scaffolds are almost identical, allowing loop regions to be swapped freely between murine and human tetranectin derivatives with retention of functionality. Swapping of loop regions between the murine and the human framework is readily accomplished within the described system of tetranectin derivative vectors, and it is anticipated, that the system can be extended to include other species (e.g. rat, old and new world monkeys, dog, cattle, sheep, goat etc.) of relevance in medicine or veterinary medicine in view of the high level of homology between man and mouse sequences, even at the genetic level. Extension of this strategy to include more species may be rendered possible as and when tetranectin is eventually cloned and/or sequenced from such species.
[0199] Because the C-type lectin ligand-binding region represents a different topological unit compared to the antigen binding clefts of the antibodies, we envisage that the selected binding specificities will be of a different nature compared to the antibodies. Further, we envisage that the tetranectin derivatives may have advantages compared to antibodies with respect to specificity in binding sugar moieties or polysaccharides. The tetranectin derivatives may also be advantageous in selecting binding specificities against certain natural or synthetic organic compounds.
[0200] Several CTLDs are known to bind calcium ions, and binding of other ligands is often either dependent on calcium (e.g. the collectin family of C-type lectins, where the calcium ion bound in site 2 is directly involved in binding the sugar ligand [Weis and Drickamer (1996)]) or sensitive to calcium (e.g. tetranectin, where binding of calcium involves more of the side chains known otherwise to be involved in plasminogen kringle 4 binding [Graversen et al. (1998)]). The calcium binding sites characteristic of the C-type lectin-like protein family are comprised by residues located in loop 1, loop 4 and β-strand 4 and are dependent on the presence of a proline residue (often interspacing loop 3 and loop 4 in the structure), which upon binding is found invariantly in the cis conformation. Moreover, binding of calcium is known to enforce structural changes in the CTLD loop-region [Ng et al. (1998a,b)]. We therefore envisage, that binding to a specific target ligand by members of combinational libraries with preserved CTLD metal binding sites may be modulated by addition or removal of divalent metal ions (e.g. calcium ions) either because the metal ion may be directly involved in binding, because it is a competitive ligand, or because binding of the metal ion enforces structural rearrangements within the putative binding site.
[0201] The trimeric nature of several members of the C-type lectin and C-type lectin-like protein family, including tetranectin, and the accompanying avidity in binding may also be exploited in the creation of binding units with very high binding affinity.
[0202] As can be appreciated from the disclosure above, the present invention has a broad general scope and a wide area of application. Accordingly, the following examples, describing various embodiments thereof, are offered by way of illustration only, not by way of limitation.

[0210] The phagemids pPmtlec and pPmtCTLD may be constructed by ligation of the Sfi I and Not I restricted DNA fragments (amplified from the pUC-mtlec plasmid with the oligonucleotide primer pair 5-CGGCTGAGCGGCCCAGCCGGCCATGGCCGAGTCACCCACTCCCAAGG-3' [SEQ ID NO:32], and 5'-CCTGCGGCCGCCACGATCCCGAACTGG-3' [SEQ ID NO:33] and with the oligonucleotide primers 5'-CGGCTGAGCGGCCCAGCCGGCCATGGCCGCCTTACAGACTGTGGTC-3' [SEQ ID NO:34] and 5'-CCTGCGGCCGCCACGATCCCGAACTGG-3' [SEQ ID NO:33], respectively) into a Sfi I and Not I precut vector pCANTAB 5E supplied by Amersham Pharmacia Biotech (code no. 27-9401-01) using standard procedures.

EXAMPLE 2
[0211] Demonstration of Successful Display of Phtlec and PhTN3 on Phages.
[0212] In order to verify that the Phtlec and PhTN3 Gene III fusion proteins can indeed be displayed by the recombinant phage particles, the phagemids pPhtlec and pPhTN3 (described in Example 1) were transformed into E. coli TG1 cells and recombinant phages produced upon infection with the helper phage M13K07. Recombinant phages were isolated by precipitation with poly(ethylene glycol) (PEG 8000) and samples of Phtlec and PhTN3 phage preparations as well as a sample of helper phage were subjected to an ELISA-type sandwich assay, in which wells of a Maxisorb (Nunc) multiwell plate were first incubated with anti-human tetranectin or bovine serum albumin (BSA) and blocked in skimmed milk or skimmed milk/EDTA. Briefly, cultures of pPhtlec and pPhTN3 phagemid transformed TG1 cells were grown at 37° C. in 2xTY-medium supplemented with 20 glucose and 100 mg/L ampicillin until A600 reached 0.5. By then the helper phage, M13KO7, was added to a concentration of 5×109 pfu/mL. The cultures were incubated at 37° C. for another 30 min before cells were harvested by centrifugation and resuspended in the same culture volume of 2×TY medium supplemented with 50 mg/L kanamycin and 100 mg/L ampicillin and transferred to a fresh set of flasks and grown for 16 hours at 25° C. Cells were removed by centrifugation and the phages precipitated from 20 mL culture supernatant by the addition of 6 mL of ice cold 200 PEG 8000, 2.5 M NaCl. After mixing the solution was left on ice for one hour and centrifuged at 4° C. to isolate the precipitated phages. Each phage pellet was resuspended in 1 mL of 10 mM tris-HCl pH 8, 1 mM EDTA (TE) and incubated for 30 min before centrifugation. The phage containing supernatant was transferred to a fresh tube. Along with the preparation of phage samples, the wells of a Maxisorb plate was coated overnight with (70 μL) rabbit anti-human tetranectin (a polyclonal antibody from DAKO A/S, code no. A0371) in a 1:2000 dilution or with (70 μL) BSA (10 mg/mL). Upon coating, the wells were washed three times with PBS (2.68 mM KCl, 1.47 mM KH2PO4, 137 mM NaCl, 8.10 mM Na2HPO4, pH 7.4) and blocked for one hour at 37° C. with 280 μL of either 3% skimmed milk in PBS, or 3% skimmed milk, 5 mM EDTA in PBS. Anti-tetranectin coated and BSA coated wells were then incubated with human Phtlec-, PhTN3-, or helper phage samples for 1 hour and then washed 3 times in PBS buffer supplemented with the appropriate blocking agent. Phages in the wells were detected after incubation with HRP-conjugated anti-phage conjugate (Amersham Pharmacia, code no. 27-9421-01) followed by further washing. HRP activities were then measured in a 96-well ELISA reader using a standard HRP chromogenic substrate assay.
[0213] Phtlec and PhTN3 phages produced strong responses (14 times background) in the assay, irrespective of the presence or absence of EDTA in the blocking agent, whereas helper phage produced no response above background readings in either blocking agent. Only low binding to BSA was observed (FIG. 26).
[0214] It can therefore be concluded that the human Phtlec and PhTN3 phages both display epitopes that are specifically recognized by the anti-human tetranectin antibody.
EXAMPLE 3
[0215] Demonstration of authentic ligand binding properties of Phtlec and PhTN3 displayed on phage
[0216] The apo-form of the CTLD domain of human tetranectin binds in a lysine-sensitive manner specifically to the kringle 4 domain of human plasminogen [Graversen et al. (1998)]. Binding of tetranectin to plasminogen can be inhibited by calcium which binds to two sites in the ligand-binding site in the CTLD domain (Kd approx. 0.2 millimolar) or by lysine-analogues like AMCHA (6-amino-cyclohexanoic acid), which bind specifically in the two stronger lysine-binding sites in plasminogen of which one is located in kringle 1 and one is located in kringle 4 (Kd approx. 15 micromolar).
[0217] To demonstrate specific AMCHA-sensitive binding of human Phtlec and PhTN3 phages to human plasminogen, an ELISA assay, in outline similar to that employed to demonstrate the presence of displayed Phlec and PhCTLD GIII fusion proteins on the phage particles (cf. Example 2), was devised.
[0218] Wells were coated with solutions of human plasminogen (10 μg/mL), with or without addition of 5 mM AMCHA. Control wells were coated with BSA. Two identical arrays were established, one was subjected to blocking of excess binding capacity with 3% skimmed milk, and one was blocked using 3% skimmed milk supplemented with 5 mM EDTA. Where appropriate, blocking, washing and phage stock solutions were supplemented by 5 mM AMCHA. The two arrays of wells were incubated with either Phtlec-, or PhTN3-, or helper phage samples, and after washing the amount of phage bound in each well was measured using the HRP-conjugated antiphage antibody as above. The results are shown in FIG. 27, panels A and B, and can be summarized as follows [0219] (a) In the absence of AMCHA, binding of human Phtlec phages to plasminogen-coated wells generated responses at 8-10 times background levels using either formulation of blocking agent, whereas human PhTN3 phages generated responses at 4 (absence of EDTA) or 7 (presence of EDTA) times background response levels. [0220] (b) In the presence of 5 mM AMCHA, binding of human Phtlec- and PhTN3 phages to plasminogen was found to be completely abolished. [0221] (c) Phtlec and PhTN3 phages showed no binding to BSA, and control helper phages showed no binding to any of the immobilized substances. [0222] (d) Specific binding of human Phtlec and PhTN3 phages to a specific ligand at moderate binding strength (about 20 micromolar level) can be detected with high efficiency at virtually no background using a skimmed-milk blocking agent, well-known in the art of combinatorial phage technology as a preferred agent effecting the reduction of non-specific binding.
[0223] In conclusion, the results show that the Phtlec and PhTN3 Gene III fusion proteins displayed on the phage particles exhibit plasminogen-binding properties corresponding to those of authentic tetranectin, and that the physical and biochemical properties of Phtlec and PhTN3 phages are compatible with their proposed use as vehicles for the generation of combinatorial libraries from which CTLD derived units with new binding properties can be selected.
EXAMPLE 4
[0224] Construction of the phage libraries Phtlec-lb001 and Phtlec-lb002.
[0225] All oligonucleotides used in this example were supplied by DNA Technology (Aarhus, Denmark).
[0226] The phage library Phtlec-lb001, containing random amino acid residues corresponding to Phtlec (SEQ ID NO: 12) positions 141-146 (loop 3), 150-153 (part of loop 4), and residue 168 (Phe in β4), was constructed by ligation of 20 μg KpnI and MunI restricted pPhtlec phagemid DNA (cf, Example 1) with 10 μg of KpnI and MunI restricted DNA fragment amplified from the oligonucleotide htlec-lib1-tp (SEQ ID NO: 39), where N denotes a mixture of 25% of each of the nucleotides T, C, G, and A, respectively and S denotes a mixture of 50% of C and G, encoding the appropriately randomized nucleotide sequence and the oligonucleotides htlec-lib1-rev (SEQ ID NO: 40) and htlec-lib1/2-fo (SEQ ID NO: 41) as primers using standard conditions. The ligation mixture was used to transform so-called electrocompetent E. coli TG-1 cells by electroporation using standard procedures. After transformation the E. coli TG-1 cells were plated on 2×TY-agar plates containing 0.2 mg ampicillin/mL and 20 glucose and incubated over night at 30° C.
[0227] The phage library Phtlec-lb002, containing random amino acid residues corresponding to Phtlec (SEQ ID NO: 12) positions 121-123, 125 and 126 (most of loop 1), and residues 150-153 (part of loop 4) was constructed by ligation of 20 μg BglII and MunI restricted pPhtlec phagemid DNA (cf, EXAMPLE 1) with 15 μg of BglII and MunI restricted DNA fragment amplified from the pair of oligonucleotides htlec-lib2-tprev (SEQ ID NO: 42) and htlec-lib2-tpfo (SEQ ID NO: 43), where N denotes a mixture of 25% of each of the nucleotides T, C, G, and A, respectively and S denotes a mixture of 50% of C and G, encoding the appropriately randomized nucleotide sequence and the oligonucleotides htlec-lib2-rev (SEQ ID NO: 44) and htlec-lib1/2-fo (SEQ ID NO: 41) as primers using standard conditions. The ligation mixture was used to transform so-called electrocompetent E. coli TG-1 cells by electroporation using standard procedures. After transformation the E. coli TG-1 cells were plated on 2×TY-agar plates containing 0.2 mg ampicillin/mL and 20 glucose and incubated overnight at 30° C.
[0228] The titer of the libraries Phtlec-lb001 and -lb002 was determined to 1.4*109 and 3.2*109 clones, respectively. Six clones from each library were grown and phagemid DNA isolated using a standard miniprep procedure, and the nucleotide sequence of the loop-region determined (DNA Technology, Aarhus, Denmark). One clone from each library failed, for technical reasons, to give reliable nucleotide sequence, and one clone from Phtlec-lib001 apparently contained a major deletion. The variation of nucleotide sequences, compared to Phtlec (SEQ ID NO: 12), of the loop-regions of the other nine clones (lb001-1, lb001-2, lb001-3, lb001-4, lb002-1, lb002-2, lb002-3, lb002-4, and lb002-5) is shown in Table 3.

EXAMPLE 5
[0229] Construction of the Phage Library PhtCTLD-lb003
[0230] All oligonucleotides used in this example were supplied by DNA Technology (Aarhus, Denmark).
[0231] The phage library PhtCTLD-lb003, containing random amino acid residues corresponding to PhtCTLD (SEQ ID NO: 15) positions 77 to 79 and 81 to 82 (loop 1) and 108 to 109 (loop 4) was constructed by ligation of 20 μg BglII and MunI restricted pPhtCTLD phagemid DNA (cf. Example 1) with 10 g of a BglII and MunI restricted DNA fragment population encoding the appropriately randomized loop 1 and 4 regions with or without two and three random residue insertions in loop 1 and with three and four random residue insertions in loop 4. The DNA fragment population was amplified, from six so-called assembly reactions combining each of the three loop 1 DNA fragments with each of the two loop 4 DNA fragments as templates and the oligonucleotides TN-lib3-rev (SEQ ID NO: 45) and loop 3-4-5 tagfo (SEQ ID NO: 46) as primers using standard procedures. Each of the three loop 1 fragments was amplified in a reaction with either the oligonucleotides loop1b (SEQ ID NO: 47), loop1c (SEQ ID NO: 48), or loop1d (SEQ ID NO: 49) as template and the oligonucleotides TN-lib3-rev (SEQ ID NO: 45) and TN-KpnI-fo (SEQ ID NO: 50) as primers, and each of the two DNA loop 4 fragments was amplified in a reaction with either the oligonucleotide loop4b (SEQ ID NO: 51) or loop4c (SEQ ID NO: 52) as template and the oligonucleotides loop3-4rev (SEQ ID NO: 53) and loop3-4fo (SEQ ID NO: 54) as primers using standard procedures. In the oligonucleotide sequences N denotes a mixture of 25% of each of the nucleotides T, C, G, and A, respectively and S denotes a mixture of 50% of C and G, encoding the appropriately randomized nucleotide sequence. The ligation mixture was used to transform so-called electrocompetent E. coli TG-1 cells by electroporation using standard procedures. After transformation the E. coli TG-1 cells were plated on 2×TY-agar plates containing 0.2 mg ampicillin/mL and 20 glucose and incubated over night at 30° C.
[0232] The size of the resulting library, PhtCTLD-lb003, was determined to 1.4*1010 clones. Twenty four clones from the library were grown and phages and phagemid DNA isolated. The nucleotide sequences of the loop-regions were determined (DNA Technology, Aarhus, Denmark) and binding to a polyclonal antibody against tetranectin, anti-TN (DAKO A/S, Denmark), analyzed in an ELISA-type assay using HRP conjugated anti-gene VIII (Amersham Pharmacia Biotech) as secondary antibody using standard procedures. Eighteen clones were found to contain correct loop inserts, one clone contained the wild type loop region sequence, one a major deletion, two contained two or more sequences, and two clones contained a frameshift mutation in the region. Thirteen of the 18 clones with correct loop inserts, the wild type clone, and one of the mixed isolates reacted strongly with the polyclonal anti-TN antibody. Three of the 18 correct clones reacted weakly with the antibody, whereas, two of the correct clones, the deletion mutant, one of the mixed, and the two frameshift mutants did not show a signal above background.

[0233] Phage Selection by Biopanning on Anti-TN Antibody.
[0234] Approximately 1011 phages from the PhtCTLD-lb003 library was used for selection in two rounds on the polyclonal anti-TN antibody by panning in Maxisorb immunotubes (NUNC, Denmark) using standard procedures. Fifteen clones out of 7*107 from the plating after the second selection round were grown and phagemid DNA isolated and the nucleotide sequence determined. All 15 clones were found to encode correct and different loop sequences.
EXAMPLE 7
[0235] Model Selection of CTLD-Phages on Plasminogen.
I: Elution by Trypsin Digestion After Panning.
[0236] In order to demonstrate that tetranectin derived CTLD bearing phages can be selected from a population of phages, mixtures of PhtCTLD phages isolated from a E. coli TG1 culture transformed with the phagemid pPhtCTLD (cf, EXAMPLE 1) after infection with M13K07 helper phage and phages isolated from a culture transformed with the phagemid pPhtCPB after infection with M13K07 helper phage at ratios of 1:10 and 1:105, respectively were used in a selection experiment using panning in 96-well Maxisorb micro-titerplates (NUNC, Denmark) and with human plasminogen as antigen. The pPhtCPB phagemid was constructed by ligation of the double stranded oligonucleotide (SEQ ID NO: 55) with the appropriate restriction enzyme overhang sequences into KpnI and MunI restricted pPhtCTLD phagemid DNA. The pPhtCBP phages derived upon infection with the helper phages displays only the wild type M13 gene III protein because of the translation termination codons introduced into the CTLD coding region of the resulting pPhtCPB phagemid (SEQ ID NO: 56).
[0237] The selection experiments were performed in 96 well micro titer plates using standard procedures. Briefly, in each well 3 μg of human plasminogen in 100 μL PBS (PBS, 0.2 g KCl, 0.2 g KH2PO4, 8 g NaCl, 1.44 g Na2HPO4, 2H2O, water to 1 L, and adjusted to pH 7.4 with NaOH) or 100 μL PBS (for analysis of non specific binding) was used for over night coating at 4° C. and at 37° C. for one hour. After washing once with PBS, wells were blocked with 400 μL PBS and 3% non fat dried milk for one hour at 37° C. After blocking wells were washed once in PBS and 0.1% Tween 20 and three times with PBS before the addition of phages suspended in 100 μL PBS, 3% non fat dried milk. The phages were allowed to bind at 37° C. for one hour before washing three times with PBS, Tween 20 and three times with PBS. Bound phages were eluted from each well by trypsin digestion in 100 μL (1 mg/mL trypsin in PBS) for 30 min. at room temperature, and used for infection of exponentially growing E. coli TG1 cells before plating and titration on 2×TY agar plates containing 20 glucose and 0.1 mg/mL ampicillin.
[0238] Initially (round 1), 1012 PhtCTLD phages (A series), a mixture of 1010 PhtCTLD phages and 1011 PhtCPB phages (B series), or a mixture of 106 PhtCTLD and 1011 PhtCPB phages (C series) were used. In the following round (round 2) 1011 phages of the output from each series were used. Results from the two rounds of selection are summarised in Table 4.

[0239] Phagemid DNA from 12 colonies from the second round of plating together with 5 colonies from a plating of the initial phage mixtures was isolated and the nucleotide sequence of the CTLD region determined. From the initial 1/10 mixture (B series) of PhtCTLD/PhtCPB one out of five were identified as the CTLD sequence. From the initial 1/105 mixture (C series) all five sequences were derived from the pPhtCPB phagemid. After round 2 nine of the twelve sequences analyzed from the B series and all twelve sequences from the C series were derived from the pPhtCTLD phagemid.

[0240] Model Selection of CTLD-Phages on Plasminogen.
[0241] II: Elution by 0.1 M Triethylamine After Panning.
[0242] In order to demonstrate that tetranectin derived CTLD-bearing phages can be selected from a population of phages, mixtures of PhtCTLD phages isolated from a E. coli TG1 culture transformed with the phagemid pPhtCTLD (cf, EXAMPLE 1) after infection with M13K07 helper phage and phages isolated from a culture transformed with the phagemid pPhtCPB (cf, EXAMPLE 6) after infection with M13K07 helper phage at ratios of 1:102 and 1:106, respectively were used in a selection experiment using panning in 96-well Maxisorb micro-titerplates (NUNC, Denmark) and with human plasminogen as antigen using standard procedures.
[0243] Briefly, in each well 3 μg of human plasminogen in 100 μL PBS (PBS, 0.2 g KCl, 0.2 g KH2PO4, 8 g NaCl, 1.44 g Na2HPO4, 2H2O, water to 1 L, and adjusted to pH 7.4 with NaOH) or 100 μL PBS (for analysis of non specific binding) was used for over night coating at 4° C. and at 37° C. for one hour. After washing once with PBS, wells were blocked with 400 L PBS and 3% non fat dried milk for one hour at 37° C. After blocking wells were washed once in PBS and 0.1% Tween 20 and three times with PBS before the addition of phages suspended in 100 μL PBS, 3% non fat dried milk. The phages were allowed to bind at 37° C. for one hour before washing 15 times with PBS, Tween 20, and 15 times with PBS. Bound phages were eluted from each well by 100 μL 0.1 M triethylamine for 10 min at room temperature, and upon neutralisation with 0.5 vol. 1 M Tris-HCl pH 7.4, used for infection of exponentially growing E. coli TG1 cells before plating and titration on 2×TY agar plates containing 20 glucose and 0.1 mg/mL ampicillin.
[0244] Initially (round 1) 1012 PhtCTLD phages (A series), a mixture of 109 PhtCTLD phages and 1011 PhtCPB phages (B series), or a mixture of 105 PhtCTLD and 1011 PhtCPB phages (C series) were used. In the following round (round 2) 1011 phages of the output from each series were used. Results from the two rounds of selection are summarised in Table 5.

[0245] Phage mixtures from the A and the B series from the second round of selection were grown using a standard procedure, and analyzed for binding to plasminogen in an ELISA-type assay. Briefly, in each well 3 μg of plasminogen in 100 μL PBS (PBS, 0.2 g KCl, 0.2 g KH2PO4, 8 g NaCl, 1.44 g Na2HPO4, 2H2O, water to 1 L, and adjusted to pH 7.4 with NaOH) or 100 μL PBS (for analysis of non specific binding) was used for over night coating at 4° C. and at 37° C. for one hour. After washing once with PBS, wells were blocked with 400 μL PBS and 3% non fat dried milk for one hour at 370C. After blocking wells were washed once in PBS and 0.1% Tween 20 and three times with PBS before the addition of phages suspended in 100 μL PBS, 3% non fat dried milk. The phage mixtures were allowed to bind at 37° C. for one hour before washing three times with PBS, Tween 20, and three times with PBS. After washing, 50 μL of a 1:5000 dilution of a HRP-conjugated anti-gene VIII antibody (Amersham Pharmacia Biotech) in PBS, 3% non fat dried milk was added to each well and incubated at 37° C. for one hour. After binding of the "secondary" antibody wells were washed three times with PBS, Tween 20, and three times with PBS before the addition of 50 μL of TMB substrate (DAKO-TMB One-Step Substrate System, code: 51600, DAKO, Denmark). Reaction was allowed to proceed for 20 min. before quenching with 0.5 vol. 0.5 M H2SO4, and analysis. The result of the ELISA analysis confirmed specific binding to plasminogen of phages in both series (FIG. 28).
EXAMPLE 9
[0246] Selection of Phages From the Library Phtlec-lb002 Binding to Hen Egg White Lysozyme.
[0247] 1.2*1012 phages, approximately 250 times the size of the original library, derived from the Phtlec-lb002 library (cf, EXAMPLE 4) were used in an experimental procedure for the selection of phages binding to hen egg white lysozyme involving sequential rounds of panning using standard procedures.
[0248] Briefly, 30 μg of hen egg white lysozyme in 1 mL PBS (PBS, 0.2 g KCl, 0.2 g KH2PO4, 8 g NaCl, 1.44 g Na2HPO4, 2H2O, water to 1 L, and adjusted to pH 7.4 with NaOH) or 1 mL PBS (for analysis of non specific binding) was used for over night coating of Maxisorb immunotubes (NUNC, Denmark) at 4° C. and at 37° C. for one hour. After washing once with PBS, tubes were filled and blocked with PBS and 3% non fat dried milk for one hour at 37° C. After blocking tubes were washed once in PBS, 0.1% Tween 20 and three times with PBS before the addition of phages suspended in 1 mL PBS, 3% non fat dried milk. The phages were allowed to bind at 37° C. for one hour before washing six times with PBS, Tween 20 and six times with PBS. Bound phages were eluted from each well by 1 mL 0.1 M triethylamine for 10 min at room temperature, and upon neutralisation with 1 M Tris-HCl pH 7.4, used for infection of exponentially growing E. coli TG1 cells before plating and titration on 2×TY agar plates containing 20 glucose and 0.1 mg/mL ampicillin. In the subsequent rounds of selection approximately 1012 phages derived from a culture grown from the colonies plated after infection with the phages eluted from the lysozyme coated tube were used in the panning procedure. However, the stringency in binding was increased by increasing the number of washing step after phage panning from six to ten.
[0249] The results from the selection procedure is shown in Table 7.

[0250] Phages were grown from twelve clones isolated from the third round of selection in order to analyse the specificity of binding using a standard procedure, and analyzed for binding to hen egg white lysozyme and human β2-microglobulin in an ELISA-type assay. Briefly, in each well 3 μg of hen egg white lysozyme in 100 μL PBS (PBS, 0.2 g KCl, 0.2 g KH2PO4, 8 g NaCl, 1.44 g Na2HPO4, 2H2O, water to 1 L, and adjusted to pH 7.4 with NaOH), or 3 μg of human β2-microglobulin, or 100 μL PBS (for analysis of non specific binding) was used for over night coating at 4° C. and at 37° C. for one hour. After washing once with PBS, wells were blocked with 400 μL PBS and 3% non fat dried milk for one hour at 37° C. After blocking wells were washed once in PBS and 0.1% Tween 20 and three times with PBS before the addition of phages suspended in 100 μL PBS, 3% non fat dried milk. The phages were allowed to bind at 37° C. for one hour before washing three times with PBS, Tween 20 and three times with PBS. After washing, 50 μL of a 1 to 5000 dilution of a HRP-conjugated anti-gene VIII antibody (Amersham Pharmacia Biotech) in PBS, 3% non fat dried milk was added to each well and incubated at 37° C. for one hour. After binding of the "secondary" antibody wells were washed three times with PBS, Tween 20 and three times with PBS before the addition of 50 μL of TMB substrate (DAKO-TMB One-Step Substrate System, code: 51600, DAKO, Denmark). Reaction was allowed to proceed for 20 min before quenching with 0.5 M H2SO4.
[0251] Results showing relatively weak but specific binding to lysozyme are summarised in FIG. 29.

EXAMPLE 13
[0259] Construction of the Phage Library PhtCTLD-lb004
All oligonucleotides used in this example were supplied by DNA Technology (Aarhus, Denmark).
[0260] The phage library PhtCTLD-lb004, containing random amino acid residues corresponding to PhtCTLD (SEQ ID NO:15) positions 97 to 102 or 98 to 101(loop 3) and positions 116 to 122 or 118 to 120 (loop 5) was constructed by ligation of 20 μg KpnI and MunI restricted pPhtCTLD phagemid DNA (cf. Example 1) with 10 μg of a KpnI and MunI restricted DNA fragment population encoding the randomized loop 3 and 5 regions. The DNA fragment population was amplified from nine primary PCR reactions combining each of the three loop 3 DNA fragments with each of the three loop 5 DNA fragments. The fragments was amplified with either of the oligonucleotides loop3a (SEQ ID NO:84), loop3b (SEQ ID NO: 85), or loop3c (SEQ ID NO:86) as template and loop5a(SEQ ID NO:87), loop5b(SEQ ID NO:88)or loop5c(SEQ ID NO:89) and loop3-4rev(SEQ ID NO:91) as primers. The DNA fragments were further amplified in PCR reactions, using the primary PCR product as template and the oligonucleotide loop3-4rev (SEQ ID NO:91) and loop3-4-stag fo (SEQ ID NO:90) as primers. All PCR reactions were performed using standard procedures.
[0261] In the oligonucleotide sequences N denotes a mixture of 25% of each of the nucleotides T, C, G, and A, respectively and S denotes a mixture of 50% of C and G, encoding the appropriately randomized nucleotide sequence. The ligation mixture was used to transform so-called electrocompetent E. coli TG-1 cells by electroporation using standard procedures. After transformation the E. coli TG-1 cells were plated on 2×TY-agar plates containing 0.2 mg ampicillin/mL and 20 glucose and incubated over night at 30° C.
[0262] The size of the resulting library, PhtCTLD-lb004, was determined to 7*109 clones. Sixteen clones from the library were picked and phagemid DNA isolated. The nucleotide sequence of the loop-regions were determined (DNA Technology, Aarhus, Denmark). Thirteen clones were found to contain correct loop inserts and three clones contained a frameshift mutation in the region.
EXAMPLE 14
[0263] Selection of Phtlec-Phages and PhtCTLD-Phages Binding to the Blood Group A Sugar Moiety Immobilised on Human Serum Albumin
[0264] Phages grown from glycerol stocks of the libraries Phtlec-lb001 and Phtlec-lb002 (cf. Example 4) and phages grown from a glycerol stock of the library PhtCTLD-lb003 (cf. Example 5), using a standard procedure, were used in an experiment designed for the selection of Phtlec- and PhtCTLD derived phages with specific affinity to the blood group A sugar moiety immobilized on human serum albumin, A-HA, by panning in 96-well Maxisorb micro-titerplates (NUNC, Denmark) using standard procedures.
[0265] Initially, the phage supernatants were precipitated with 0.3 volume of a solution of 20% polyethylene glycol 6000 (PEG) and 2.5 M NaCl, and the pellets re-suspended in TE-buffer (10 mM Tris-HCl pH 8, 1 mM EDTA). After titration on E. coli TG-1 cells, phages derived from Phtlec-lb001 and -lb002 were mixed (#1) in a 1:1 ratio and adjusted to 5*1012 pfu/mL in 2*TY medium, and phages grown from the PhtCTLD-lb003 library (#4) were adjusted to 2.5*1012 pfu/mL in 2*TY medium.
[0266] One microgram of the "antigen", human blood group A trisaccharide immobilised on human serum albumin, A-HA, (Glycorex AB, Lund, Sweden) in 100 μL PBS (PBS, 0.2 g KCl, 0.2 g KH2PO4, 8 g NaCl, 1.44 g Na2HPO4, 2H2O, water to 1 L, and adjusted to pH 7.4 with NaOH), in each of three wells, was coated over night at 4° C. and at room temperature for one hour, before the first round of panning. After washing once with PBS, wells were blocked with 300 μL PBS and 3% non fat dried milk for one hour at room temperature. After blocking wells were washed once in PBS and 0.1% Tween 20 and three times with PBS before the addition of a mixture of 50 μL of the phage suspension and 50 μL PBS, 6% non fat dried milk. The phages were allowed to bind at room temperature for two hours before washing eight times with PBS, Tween 20, and eight times with PBS. Bound phages were eluted from each well by trypsin digestion in 100 μL (1 mg/mL trypsin in PBS) for 30 min. at room temperature, and used for infection of exponentially growing E. coli TG1 cells before plating and titration on 2×TY agar plates containing 20 glucose and 0.1 mg/mL ampicillin.
[0267] In the second round of selection, 150 μL of crude phage supernatant, grown from the first round output colonies, was mixed with 150 μL PBS, 6% non fat dried milk, and used for panning distributing 100 μL of the mixture in each of three A-HA coated wells, as previously described. Stringency in binding was increased by increasing the number of washing steps from 16 to 32. 300 μL of phage mixture was also used for panning in three wells, which had received no antigen as control.
[0268] In the third round of selection, 150 μL of crude phage supernatant, grown from the second round output colonies, was mixed with 150 μL PBS, 6% non fat dried milk, and used for panning distributing 100 μL of the mixture in each of three A-HA coated wells, as previously described. The number of washing steps was again 32. 300 μL of phage mixture was also used for panning in three wells, which had received no antigen as control.
[0269] The results from the selection procedure are summarised in Table 8

[0270] 48 clones from each of the #1 and #4 series were picked and grown in a 96 well microtiter tray and phages produced by infection with M13K07 helper phage using a standard procedure. Phages from the 96 phage supernatants were analyzed for binding to the A-HA antigen and for non-specific binding to hen egg white lysozyme using an ELISA-type assay. Briefly, in each well 1 μg of A-HA in 100 μL PBS (PBS, 0.2 g KCl, 0.2 g KH2PO4, 8 g NaCl, 1.44 g Na2HPO4, 2H2O, water to 1 L, and adjusted to pH 7.4 with NaOH) or 1 μg of hen egg white lysozyme in 100 μL PBS (for analysis of non specific binding) was used for over night coating at 4° C. and at room temperature for one hour. After washing once with PBS, wells were blocked with 300 μL PBS and 3% non fat dried milk for one hour at room temperature. After blocking wells were washed once in PBS and 0.1% Tween 20 and three times with PBS before the addition of 50 μL phage supernatant in 50 μL PBS, 6% non fat dried milk. The phage mixtures were allowed to bind at room temperature for two hours before washing three times with PBS, Tween 20, and three times with PBS. After washing, 50 μL of a 1:5000 dilution of a HRP-conjugated anti-gene VIII antibody (Amersham Pharmacia Biotech) in PBS, 3% non fat dried milk, was added to each well and incubated at room temperature for one hour. After binding of the "secondary" antibody wells were washed three times with PBS, Tween 20, and three times with PBS before the addition of 50 μL of TMB substrate (DAKO-TMB One-Step Substrate System, DAKO, Denmark). Reaction was allowed to proceed for 20 min. before quenching with 0.5 M H2SO4, and analysis. The result of the ELISA analysis showed "hits" in terms of specific binding to A-HA of phages in both series (FIGS. 34 and 35), as judged by a signal ratio between signal on A-HA to signal on lysozyme at or above 1.5, and with a signal above background.
[0271] From the #1 series 13 hits were identified and 28 hits were identified from the #4 series.
