Development of a monoclonal antibody specific for serotype 3 rotavirus strains.
Monoclonal antibodies were prepared against serotype 3 simian rotavirus SA11. Antigenic analysis of 18 hybridoma cell lines secreting monoclonal antibodies by radioimmunoprecipitation and Western blot revealed that seven monoclonals were directed against the major inner capsid protein VP6, four against VP3, an outer capsid protein with hemagglutinating activity, and one against VP7, the main outer capsid protein of the virus. The specificity of six monoclonals could not be determined. One monoclonal (1P14E2) directed against VP3 showed serotype 3-specific neutralizing activity. This monoclonal, which recognized only serotype 3 viruses in an enzyme-linked immunosorbent assay, could be useful in assays for serotyping rotavirus directly in stool samples.
