Antigenic determinant. See epitope

Antigen A molecule that is capable of binding to an antibody. Antigenic Determinant See Epitope. 

The fusion of an Immortal myeloma cell and a single B lymphocyte yields a hybrid cell that can proliferate indefinitely, forming a clone called a hybridoma (see Figure 6-38). Because each Individual B lymphocyte produces antibodies specific for one antigenic determinant (epitope), a hybridoma produces only the mono-... 

Chemical similarities can quite easily explain the observation of cross-allergies. Small conformational differences are enough indeed to create common epitopes (etymologically, superficial place ). An epitope is a part of molecule with a specific three-dimensional structure. One more time, we can see the importance of molecular structures in biology. Epitope is also called antigenic determinant. It can be incorporated in a macromolecular antigen by a group of specific amino acids, often exposed on the surface of the molecule (Fig. 3.27). ...
