Abstract: The present invention relates to antibodies with pH dependent binding to its antigen such that the affinity for antigen binding at physiological pH (i.e., pH 7.4) is greater than at endosomal pH (i.e., pH 6.0 or 5.5). In other words, the KD or koff ratio at pH 5.5/pH 7.4 or at pH 6.0/pH 7.4 is more than, or ranges between, 2, 3, 4, 8, 10, 16, 20, 30, 40, or 100 or more. Such pH dependent antibodies preferentially dissociate from the antigen in the endosome. This can increase antibody half life, as compared to antibodies with equivalent KDs at pH 7.4 but with no pH dependent binding, when the antigen is one that undergoes antigen-mediated clearance (e.g., PCSK9). Antibodies with pH dependent binding can decrease total antigen half life when the antigen undergoes reduced clearance when bound to antibody (e.g., IL6). Antibodies with pH dependent binding can also prolong the decrease in antigen which is not antibody-bound.

Abstract: A method of mutagenesis by which a predetermined amino acid is introduced into each and every position of a selected set of positions in a preselected region (or several different regions) of a polypeptide to produce a library of polypeptide analogs is disclosed. The method is based on the premise that certain amino acids play a crucial role in the structure and function of proteins and thus is capable of identifying and distinguishing functional amino acid residues (“hot spots”) from non-functional amino acids residues (“cold spots”) within a polypeptide or portion thereof. Libraries can be generated which contain only desired polypeptide analogs and are of reasonable size for screening. The libraries can be used to study the role of specific amino acids in polypeptide structure and function and to develop new or improved polypeptides such as antibodies, antibody fragments, single chain antibodies, enzymes, and ligands.
