Abstract

Antibody affinity is the strength with which antibody binds to its target antigen. It is influenced by a variety of factors including valency and the precise fit of the antigen in the antigen binding groove. Antibody affinity increases over time following contact or repeated immunization with certain types of antigen. The affinity of an antibody may have an influence on its function.
