Benefits of technology

[0035] A major advantage of the methods of the invention derives from the fact that new binding specificities can be rapidly developed for use in a variety of ways, including the development of ligands with altered specificity for receptor, receptors with altered specificity for ligand, altered and / or increased antibody binding specificity, and new proteins or polypeptides that can bind oligosaccharides, nucleic acids, and the like.

Problems solved by technology

Typically, the mutagenesis is site-directed, and therefore laborious depending on the systematic choice of mutation to induce in the protein.

Abstract

The present invention describes methods for producing binding sites on polypeptides, and particularly for producing binding sites within the CDR regions of immunoglobulin heavy or light chains that are displayed on the surface of filamentous phage particles. The invention also describes oligonucleotides useful for preparing the binding sites, and human monoclonal antibodies produced by the present methods.
