Abstract

A 64 kilodalton (kDa) surface protein was isolated from the water-extracted materials from Mycobacterium bovis strain BCG, the determinants of which are antigenically shared by a 64 kDa major surface antigenic component of line 10 hepatoma cells. The 64 kDa protein showed anti-line 10 tumor activity in pre-immunized guinea pigs, and this suggest that the BCG 64 kDa protein is probably identical with the tumor specific antigen.

摘要

从牛分枝杆菌卡介苗株的水提取物中分离出一种64千道尔顿（kDa）的表面蛋白，其决定簇与10号线肝癌细胞的一种64 kDa主要表面抗原成分具有共同抗原性。该64 kDa蛋白在预先免疫的豚鼠中显示出抗10号线肿瘤活性，这表明卡介苗64 kDa蛋白可能与肿瘤特异性抗原相同。
