Abstract
Syngeneic anti-(anti-Id) antibodies were prepared against BALB/c anti-A48Id antibodies, BALB/c anti-460Id monoclonal antibodies, and A/J anti-J558 IdI monoclonal antibodies. With these anti-(anti-Id) antibodies we identified cross-reactive idiotypes on syngeneic and homologous anti-A48Id and anti-460Id antibodies. By contrast, tbe idiotypic determinants of A/J anti-J558 IdI monoclonal antibodies were not shared by other syngeneic, homologous, or xenogenic anti-J558 IdI or IdX antibodies. These results suggest that idiotype-antiidiotype reactions that serve as regulatory controls within the immune system are characteristic for each particular antigen system, strain, or species and that such interactions make the system self-limited with respect to the whole antild repertoire.
