Abstract

The sera of hamsters carrying tumours induced by injection of TSV~5~Cl~2~ cells and the sera of animals immunized with these cells or with SV40 itself or its purified capsids have a slow cytotoxicity activity in the presence of fresh guinea pig complement on SV40‐transformed cell strains of any origin. The responsible antigen is dependent on the SV40 genome and is associated with the cytoplasmic membranes of the transformed cells. By means of absorption of the antisera with subcellular fractions it has been correlated with antigen “C” present in the cytoplasm of SV40‐transformed cells. It is different from antigen “S” shown by the immunofluorescence test, and its relation with TSTA is discussed.

It was shown previously that mouse bone marrow cells transformed by simian virus 40 (SV40) show a reversible cell density-dependent phenotypic transition between the nonmacrophage (rapidly growing) and the macrophage (stationary) states; cells in low-density cultures are in the growing phase, expres
