Idiotopes
（重定向自Idiotope）
An idiotope is the unique set of antigenic determinants (epitopes) of the variable portion of an antibody. In some cases it can be the actual antigen-binding site, and in some cases it may comprise variable region sequences outside of the antigen-binding site on the antibody itself. Thus each antibody would have multiple idiotopes; and the set of these individual idiotopes is termed the idiotype of the antibody.
