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. WebHaptens vs. epitopes Peptides and other small molecules that are used as antigens are referred to as haptens. They are able to act as recognition sites for production of specific antibodies but cannot by themselves stimulate the necessary immune response. Haptens can be made immunogenic by coupling them to a suitable carrier molecule.

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.
