WebJun 1, 2024 · An epitope is an immunogenic region of an antigen (Ag) that can be recognized by a cognate paratope of an antibody (Ab), known as B cell epitopes (BCEs), or T cell receptors, known as T cell epitopes (TCEs), the interaction of which results in humoral and/or cellular immune responses, respectively.
Antigen-antibody interaction, or antigen-antibody reaction, is a specific chemical interaction between antibodies produced by B cells of the white blood cells and antigens during immune reaction.
