Patent application numberDescriptionPublished
20080233100TARGETED ENZYMES - The present invention provides targeted enzymes that bind to targets better than the corresponding pre-targeted enzymes bind the target under like conditions, methods of making targeted enzymes, methods of using targeted enzymes to treat diseases, and pharmaceutical compositions comprising targeted enzymes.09-25-2008
20080234465EXPRESSION IN FILAMENTOUS FUNGI OF PROTEASE INHIBITORS AND VARIANTS THEREOF - Described herein are protease inhibitors, variants thereof and methods for their production.09-25-2008
20090011489MULTIPLY-SUBSTITUTED PROTEASE VARIANTS - Novel enzyme variants including protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease, Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue correspond to positions 27, 45, 170, 181, 251 and 271 of 01-08-2009
20090060933PROTEASES PRODUCING AN ALTERED IMMUNOGENIC RESPONSE AND METHODS OF MAKING AND USING THE SAME - The present invention provides novel protein variants that exhibit reduced immunogenic responses, as compared to the parental proteins. The present invention further provides DNA molecules that encode novel variants, host cells comprising DNA encoding novel variants, as well as methods for making proteins less allergenic. In addition, the present invention provides various compositions that comprise these proteins that are less immunogenic than the wild-type proteins.03-05-2009
20090093393Methods For Selective Targeting - A selective targeting method is disclosed comprising contacting a library of ligands, particularly a peptide library, with an anti-target to allow the ligands to bind to the anti-target; separating the non-binding ligands from the anti-target bound ligands, contacting the non-binding anti-target ligands with a target allowing the unbound ligands to bind with the target to form a target-bound ligand complex; separating the target-bound ligand complex from ligands which do not bind to the target, and identifying the target-bound ligands on the target-bound ligand complex wherein the target-bound ligands have a K04-09-2009
20110076260Proteases Producing an Altered Immunogenic Response and Methods of Making and Using the Same - The present invention provides novel protein variants that exhibit reduced immunogenic responses, as compared to the parental proteins. The present invention further provides DNA molecules that encode novel variants, host cells comprising DNA encoding novel variants, as well as methods for making proteins less allergenic. In addition, the present invention provides various compositions that comprise these proteins that are less immunogenic than the wild-type proteins.03-31-2011
20110097783Proteases from gram-positive organisms - The present invention relates to the identification of novel metallo-proteases (MP) in Gram-positive microorganisms. The present invention provides the nucleic acid and amino acid sequences for 04-28-2011

20110098184Competitve differntial screeing - The invention is drawn to a novel method useful for screening. In particular, the present invention provides methods for competitive differential screening. In some preferred embodiments, the present invention provides methods for competitive differential screening that facilitate the identification of tight binders. In some preferred embodiments, the agents used in the methods of the present invention comprise tight and weak binders. In other embodiments, the present invention provides methods that utilize competitive binders that recognize and bind targets, but with binding that is less strong than that of binders of interest.04-28-2011
