[The antigen of transplantable cells immunologically related to the antigen of the normal human gastric mucosa].

A newly detected antigen common for transplantable HeLa-like cell lines and human gastric mucosa has been revealed in all parts of the stomach and in highly differentiated gastric adenocarcinomas in humans. It is localized in the basal area of tall columnar cells in the mucosa and has one immunologically active subunit with molecular weight of 39 kDa. The antigen differs from the other earlier described gastrointestinal antigens in its localization in the organs and cells and in other characteristics.
