title: Intertypic cross-neutralization of polioviruses by human monoclonal antibodies.
abstract: Human B cell lines producing monoclonal antibodies (mAbs) reactive with poliovirus type 1 were generated by transformation with Epstein-Barr virus (EBV) B 95-8 of tonsillar lymphocytes from several immune donors. EBV-transformed cells were cloned in semisolid agarose. Some neutralizing (Nt) human mAbs recognized and neutralized only poliovirus type 1, whereas other Nt mAbs neutralized either poliovirus type 1 and 2 or all three serotypes. mAbs reactive with poliovirus type 1 and 3 but not with type 2 were not detected. Immunoprecipitation of radiolabeled poliovirus type 1 with cross-reactive human Nt mAbs was inhibited competitively by preincubation of mAbs with cold poliovirus type 3 and/or 2.
