Summary Baculovirus-derived recombinant simian virus 40 (SV40) large tumor antigen (SV40 T-Ag), a monoclonal antibody specific for SV40 T-Ag (Ab-1 preparation), and a monoclonal anti-idiotypic antibody (anti-Id), designated 58D, were used to analyze the humoral immune response of Balb/c mice either immunized with recombinant SV40 T-Ag or challenged with SV40-transformed cells. Inhibition assays indicated that antibodies from mice immunized with SV40 T-Ag and from those bearing SV40 tumor inhibited the SV40 T-Ag/Ab-1 reaction. These data suggested that the antibody response in immunized or tumorchallenged mice recognized similar epitope(s) on SV40 T-Ag to that detected by the monoclonal Ab-1. These anti-(SV40 T-Ag) response antibodies also inhibited the Ab-1/anti-Id reaction and recognized the anti-Id in direct binding assays. Together, these data indicate that murine anti-(SV40 T-Ag) responses shared an idiotope with a monoclonal anti-(SV40 T-Ag) Ab-1 preparation. This idiotope, which is recognized by the monoclonal anti-Id preparation, 58D, appears to be involved in the humoral immune response to SV40 T-Ag in both SV40-T-Ag-immunized and tumor-bearing mice. The monoclonal anti-Id preparation may represent a focal point for manipulating the humoral immune response to tumors induced by SV40-transformed cells.
