Characterization of Monoclonal Antibodies against Human Parvovirus B19

抄録

Eleven hybridoma cell lines producing mouse monoclonal antibodies (mAbs) against human parvovirus B19 were established. Their specificity was as follows. Approximately 5% of fetal erythroid cells inoculated with B19 reacted with all the mAbs and with anti-B19 positive human serum, but not with negative serum by indirect double immunofluorescence staining. All the mAbs recognized both VP-1 (84 kDa) and VP-2 (58 kDa) capsid proteins of B19 virions propagated in vitro and in vivo by Western blotting, and immunoprecipitated B19 virions.
