Comprehensive epitope analysis of monoclonal anti-proenkephalin antibodies using phage display libraries and synthetic peptides: revelation of antibody fine specificities caused by somatic mutations in the variable region genes.


Filamentous phage libraries, displaying 6, 12 or 20 amino acid residue peptides at the N terminus of coat protein pIII were used to define and localize the epitopes of 15 monoclonal antibodies raised against human proenkephalin, a neuropeptide precursor. Eight monoclonal antibodies (PE14 to PE19, PE23 and PE25), which inhibit each other's binding to… (More)
