an antigenic determinant located in an unexposed region of a molecule so that it is prevented from interacting with receptors on lymphocytes, or with antibody molecules, and is unable to induce an immune response; it may appear following stereochemical alterations of molecular structure.
Antibodies and antigens. Antigens are classically defined as any foreign substance that elicits an immune response. They are also called immunogens. The specific region on an antigen that an antibody recognizes and binds to is called the epitope, or antigenic determinant.An epitope is usually made up of a 5-8 amino acid long chain on the surface of the protein.he specific region on an antigen that an antibody recognizes and binds to is called the epitope, or antigenic determinant.
