title: Public and individual idiotopes in the anti-poly(Glu60, Ala30, Tyr10) response: analysis by monoclonal antibodies.
abstract: From BALB/c mice immunized with anti-GAT monoclonal antibody (mAb) G5, we have obtained anti-idiotypic mAb against individual (or private) idiotopes, expressed by G5 as well as anti-GAT mAb, that are heteroclitic because they recognize poly-(Glu50, Tyr50) (GT) better than poly(Glu60, Ala30, Tyr10) (GAT). From BALB/c mice immunized with BALB/c polyclonal anti-GAT antibodies, anti-idiotypic mAb directed against public idiotopes expressed following GAT immunization in all individuals of all mouse strains tested have been obtained. Nine anti-idiotypic mAb were studied in detail. One of these mAb recognizes only polyclonal anti-GAT antibodies; the other eight recognize polyclonal anti-GAT antibodies and anti-GAT mAb. The distribution of the structures recognized by the different anti-idiotypic mAb on a battery of 20 anti-GAT mAb allows definition of two families of public idiotopes.
