title: Monoclonal antibody to simian virus 40 small t.
abstract: A monoclonal antibody, PAb280, was produced that recognizes simian virus 40 (SV40) small t but does not react with SV40 large T. The specificity of the antibody was analyzed by immunoprecipitation of labeled cell extracts, Western blotting, and immunocytochemistry. Small t was found to accumulate late in the SV40 lytic cycle and was localized in both the cytoplasm and the nucleus of cells infected with wild-type SV40. Importantly, antibodies against determinants common to SV40 large T and small t did not appear to be able to recognize the cytoplasmic form of SV40 small t at the immunocytochemical level. The localization of small t within the nucleus appeared to be distinct from that of large T.
