Phage Display Selection of Antibody Libraries: Panning Procedures.

The mining of naive, immune, and synthetic antibody repertoires by phage display has been widely applied to the de novo generation and in vitro evolution of monoclonal antibodies from multiple species. Once built, phage display antibody libraries can be selected by a variety of different strategies tailored toward the desired antigen binding properties. Here, we describe the selection of antibody libraries generated in a phage display vector of the pComb3 phagemid family. The approach includes panning procedures for immobilized antigens, biotinylated antigens in solution, and cell surface antigens. Although the typical format of these antibody libraries is human Fab or chimeric nonhuman/human Fab, the basic selection strategies provided in this protocol are compatible with a variety of formats.
