The therapeutic efficacy of antibodies is closely related to their ability to recognize and bind specific epitopes on target antigens. Epitopes, or antigenic determinants, are a group of amino acids or other chemical groups that are part of a molecule to which an antibody attaches itself. Epitope characterization can help reveal the mechanism of antibody binding and apply intellectual property (patent) protection for novel antibodies, in addition to designing antibodies with high specificity and minimal cross-reactivity.
