Abstract: Engineered binding proteins are provided. In some cases, the parent protein corresponding to the engineered protein has a three-layer swiveling ?/?/? domain. In other cases, the parent protein corresponding to the engineered protein has a rubredoxin-like fold. At least one portion of the primary sequence of the engineered protein is determined by an engineering scheme. In some case, the engineered protein is characterized by an ability to bind to a compound that the parent protein does not bind. In some cases, the parent protein is derived from a domain of a chaperonin or a rubredoxin. One form of engineering scheme used is a randomization scheme. A method for making libraries of engineered proteins, all based on a single parent protein is provided. Methods to identify proteins that bind to compounds of interest in libraries of engineered libraries are provided. An array of engineered proteins immobilized on a support is provided.

Abstract: Heterofunctional crosslinking groups are provided having the formula: wherein W is a covalent core component; L1, L2 and L3 are independently linking groups; X is a non-covalent or reversibly covalent protein tag binder; Y is a activatable covalent linking group; and Z is a protected or unprotected covalent crosslinking group.

Abstract: Disclosed herein are humanized antibodies that bind to an epitope on the F protein of respiratory syncytial virus. The humanized antibodies were designed by comparing the canonical CDR structure types of the CDRs from a non-human antibody (HNK20) to the canonical CDR structure types found in the human antibody germline sequences as the basis for selecting human variable region frameworks in a method denoted “super-humanization.” Human antibody variable regions having the same or similar canonical CDR structure types as the non-human CDR provided a subset of candidate sequences from which to select the human frameworks. Chimeric variable regions were made comprising the non-human CDRs grafted in corresponding locations into the human frameworks from the candidate human variable regions.

Abstract: This invention provides materials and methods for the site specific attachment of virtually any moiety to a layered silicate surface. The methods involve covalently attaching the moiety to an arginine tag; and contacting the arginine tag with the layered silicate (e.g., mica).

Abstract: Expression vectors for expressing multimeric polypeptides that are anchored on surfaces of genetically replicable packages are disclosed. The expression vectors include a vector segment encoding a polypeptide sequence having three polypeptide segments. One of the segments contains a cleavable peptide sequence cleavable by a proteolytic agent, and another segment has an anchoring peptide sequence for anchoring the multimeric polypeptide to the surface of the genetically replicable package. The cleavable peptide sequence is cleaved by the proteolytic agent and the first segment associates with the third segment to form the multimeric polypeptide. Also disclosed are methods, host cells, and kits employing the expression vectors.

Abstract: Protein arrays and protein-coated substrates for the parallel, in vitro screening of biomolecular activity are provided. Methods of using the protein-coated substrates and protein arrays are also disclosed. A plurality of different members of a single protein family may be immobilized on the protein-coated substrate or array. The protein-coated substrates and protein arrays are particularly useful in high-throughput drug screening and clinical diagnostics.

Abstract: This invention provides methods for screening populations of phage-displayed polypeptides that are particularly well-suited for high-throughput screening. The methods do not require the clearing of cells from a culture used to obtain the population of phage or other replicable genetic packages. Accordingly, the invention provides methods for forming complexes between a replicable genetic package displaying a polypeptide fusion and a target molecule in an uncleared cell culture containing replicable genetic package. Compositions made up of an uncleared cell culture containing replicable genetic packages displaying a polypeptide fusion and a target molecule are provided in the invention as well.

Abstract: Improved methods for making antibody fragments, preferably F(ab′)2 fragments from various classes and subclasses of antibodies is described. Pretreatment of antibodies with deglycosylases or cellular inhibition of glycosylation during expression, yields antibodies having improved susceptibility towards protease cleavage, preferably pepsinolysis, which yields F(ab′)2 antibody fragments. Compositions resulting from such methods are further disclosed.
