a specific site on an immunogen that stimulates specific immune responses, such as the production of antibodies or activation of immune cells
a unique shape or a marker on the surface of an antigen that triggers an antibody response
also known as antigenic determinant A localized region on the surface of an antigen which antibody molecules can identify and bind
Site on an antigen and an antibody allowing the antibody to recognize and bind specifically to this antigen
(or immunodominant region) - The minimal structural unit of an antigen, recognizable for antibodies and lymphocyte antigenic receptors
A unique shape or marker carried on an antigen's surface, which triggers a corresponding antibody response
That part of a biomolecule (such as a protein) that is the target of an immune response
A molecular region on the surface of an antigen capable of eliciting an immune response and of combining with the specific antibody produced by such a response
Specific region of an antigen that binds to an antibody or a T-cell receptor Also known as the antigenic determinant (Alberts)
