title: Identification of the specificity of isolated phage display single-chain antibodies using yeast two-hybrid screens.
abstract: A method is described for the identification of the antigen recognised by an scFv isolated from an antibody phage display library using selection against a complex mixture of proteins (e.g. intact cells, purified cell surface membranes, and tissue sections). The method takes advantage of a yeast two-hybrid system that additionally allows for reorganization of post-translational modifications to the bait and target proteins. This technique is therefore especially useful for identifying surface-expressed antigens.
