Epitope Description & Function Britannica

WebThe antibodies produced by B cells are targeted specifically to the epitopes that bind to the cells’ antigen receptors. Thus, the epitope also is the region of the antigen that is recognized by specific antibodies, which bind to and remove the antigen from the body. Many antigens have a variety of distinct epitopes on their surfaces. WebAn epitope, also known as an antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, and T cells. The latter can use epitopes to distinguish between different antigens, and only binds to their specific antigen. In antibodies, the binding site for an epitope is called a paratope.
