Epitope and hapten
WebIn Jerne’s system, ‘haptens’ are a subset of epitopes and thus can be even smaller than a typical epitope. The antigen-binding site of antipolysaccharide antibodies holds up to six sugar residues; antipeptide antibodies accommodate up to four amino acids; somewhat larger epitopes can be recognized on native protein antigens. WebJan 17, 2024 · Sometimes the small-molecule hapten can block immune response to the complete antigen by preventing the adduct from binding to the antibody, a process called hapten inhibition. In this case, the hapten acts as the epitope for the antigen, which binds to the antibodies without causing a response.
