Antibodies to murine leukemia virus gp70 and p15(E) in sera of BALB/c mice immunized with syngeneic chemically induced sarcomas

J M Klitzman et al. J Immunol. 1980 Jun.

Abstract

The sera of BALB/c mice immunized with syngeneic methylcholanthrene-induced sarcomas commonly contain antibodies that react with the immunizing tumor line and also with other chemically induced sarcomas. Three lines of evidence suggest that the cross-reactive antibodies are directed against antigenic determinants of gp70 and p15(E), envelope proteins of endogenous murine leukemia virus (MuLV). 1) The antibodies bind only to sarcomas expressing MuLV antigens, 2) they are removed by absorption with purified MuLV antigens, and 3) they precipitate proteins identified as gp70 and p15(E) from 125I-labeled sarcoma cell lysates.
