[Antigens common to Mycobacterium bovis (BTsZh) and several malignant and normal tissues of laboratory animals].

Agglutination, gel precipitation and immunoelectrophoresis tests demonstrated the presence of antigens common for the Mycobacterium bovis (BCG) and some malignant and normal rat tissue cells. The method of absorption of immune sera in the agglutination test showed that this antigen was specific for the BCG microorganisms and cells of primary induced tumours of rat muscle tissue. This antigen had the electrophoretic mobility in the beta-globulin zone.
