Question

Quizplus · Accepted Answer

A large antigen is likely to have many different epitopes, or antigenic determinants, on its surface. Each epitope can stimulate a distinct immune response, leading to the formation of antibodies with specificity for that particular epitope. Therefore, a large antigen can potentially elicit a diverse range of immune responses.
