Abstract:
A library of murine monoclonal antibodies against the prototype Enterovirus-70 (EV-70) strain, J670/71, was made for the purpose of studying the immunologically reactive determinants of the virus. Each of the monoclonal antibodies reacted with several other strains of Enterovirus-70 when tested by immunofluorescence. However, none of these monoclonal antibodies reacted with any other picornavirus tested. It was found that all of the monoclonal antibodies precipitated EV-70 viral proteins 1C and 1D in radio-immunoprecipitation assays. However, only one of these monoclonal antibodies, an IgG3 kappa, was capable of neutralizing the virus.
