20080237124Manufacture of Chromatography Matrices - The present invention relates to a method of manufacturing a chromatography matrix comprising providing a polysaccharide carrier comprising available hydroxyl groups; and reacting said hydroxyl groups with vinyl sulphonate to provide a sulphonate-functionalized (S-functionalized) cation exchanger. The hydroxyl groups of the carrier may be hydroxyls of the agarose polymer; or alternatively they may be provided on extenders such as polyhydroxyfunctional polymers. In one embodiment, the carrier is made of agarose with improved flow pressure properties.10-02-2008
20080249289Manufacture of a Chromatography Matrix - The present invention relates to method of manufacturing a sulphonate-functionalized (S-functionalized) cation exchanger, which method comprises reacting olefinic groups with bisulphite in the presence of at least one amine oxide, such as N-methyl morpholine oxide (NMO). The olefinic groups of the carrier may be allyl groups; which may be provided on extenders such as polyhydroxyfunctional polymers. In one embodiment, the carrier is made of agarose with improved flow pressure properties.10-09-2008
20080283792Separation Medium with Various Functionalities - The present invention relates to a separation medium with various functionalities suitable for, for example, isolation of proteins, cells, and viruses and also for diagnostic applications and cell cultivation. The separation medium comprises magnetic metal particles, preferably coated with an inert synthetic polymer, and pre-functionalised beads. These particles and beads are provided encapsulated in a hydrophilic porous polymer, preferably agarose. The beads may be used for cell cultivation or for chromatography. When the beads are used for chromatography the agarose layer may be provided with ligands having affinity for selected biomolecules.11-20-2008
20090092837MAGNETIC BEADS - The present invention relates to magnetic beads in the form of composite beads with an inner core of metal particles, which are coated with an inert synthetic polymer and thereafter a hydrophilic porous polymer, preferably dextran. This provides porous biocompatible beads without metal leakage. This construction also allows for simple and convenient handling of cell expansion media by magnetism.04-09-2009
20090138208IMMUNOGLOBULIN G BINDING POCKET - The present invention relates to a human IgG binding pocket comprised of a first interacting surface, which originates from an IgG κ light chain, and a second interacting surface, which originates from an IgG heavy chain, which amino acids are strictly conserved between human IgGs of κ-type. The invention also embraces an isolated and purified polypeptide, which comprises said binding pocket. Further, the invention relates to various methods of using the novel binding pocket, such as in screening for identification of chemical entities capable of selective binding thereof, and in other experimental and/or virtual methods for design and/or identification of chemical entities capable of selective binding thereof.05-28-2009
