title: The Mycobacterium bovis BCG 64-kDa surface protein is antigenically shared with different mouse tumor cells and has anti-tumor activity in immunized mice.
abstract: The Mycobacterium bovis BCG 64-kDa surface protein, which was found to share antigenic determinants with line 10 hepatoma cells and showed anti-line 10 tumor activity in immunized guinea pigs, has also been found to share common antigenic determinants with Meth A, CT-26 and RL female 1 mouse tumor cells. The 64-kDa protein also demonstrated anti-tumor activity in immunized mice and 37% of the animals challenged with Meth A tumor cells and 50% of those challenged with CT-26 tumor cells completely rejected further tumor growth in the immunized mice. All these data clearly suggest that BCG 64 kDa protein is probably identical with the tumor specific antigen.
