The antigenic determinant sites on an antigen are called?

Epitopes are the specific parts of an antigen that antibodies or T-cell receptors recognize and bind. This small region, which can be a short linear sequence or a folded, three-dimensional surface, is what determines the specificity of the immune response. The part of the antibody that actually binds to this site is called the paratope, not a site on the antigen itself. While “antigenic determinants” is terminology that has been used to describe the same idea, epitopes is the standard, most precise term for the region of the antigen that is recognized.
