Specific location on antibodies to which they bind to antigens.

See also epitope/antigenic determinant.


Figure legend: A complex antigen, especially a protein, can be differentiated into a number of distinct epitopes (a.k.a., antigenic determinants). It is to these epitopes that the antigen-binding site of an antibody actually binds (antibody not shown in full).
