How do large antigens interact with antibodies? A) The region of contact between antibodies and antigens is very narrow, allowing greater specificity. B) Large antigens will contact the entire antibody, including the F_c region. C) All six CDRs of the antibody can make contact with a specific epitope. D) A single CDR of the antibody contacts multiple epitopes of the antigen. E) None of the answers is correct.

Question

Quizplus · Accepted Answer

Large antigens interact with antibodies through specific regions known as epitopes. Each antibody has six complementarity-determining regions (CDRs) that can potentially make contact with a specific epitope on the antigen, allowing for a highly specific interaction. This specificity is crucial for the immune system's ability to recognize and neutralize a wide variety of pathogens.
