| Abstract: | A stable hybridoma cell line, IIG8-203-2, that secretes a monoclonal antibody of the immunoglobulin subclass M was obtained by fusion of mouse myeloma cells with spleen cells of mice that had been immunized with the viral polypeptide VP2 of simian virus 40. The monoclonal antibody recognizes viral polypeptides that migrate with VP2 polypeptides in a sodium dodecyl sulfate-polyacrylamide gel. It also recognizes two intracellular polypeptides (29,000 and 37,000 daltons) in a detergent-insoluble fraction extracted 30 h after virus infection of TC7 cells. |
