Group‐specific antigen of murine leukemia viruses in mice of low‐leukemic strains

Abstract

Abstract The distribution of group‐specific antigen of murine leukemia viruses (MuL V‐gs) was studied in mice of low‐leukemic strains: C57BL/6, C57BL/10Sn, BALB/c and others. A rabbit monospecific anti‐MuLV‐gs serum was used for the antigen detection. The analyses were carried out by an indirect immunoradioautography technique which permitted the detection of trace amounts of the antigen. MuLV‐gs was found in the spleen of mice of all strains studied. It was present in mouse embryos as well as in adult animals.
