[Immunohistological study of an intestinal antigen].
The localization of an intestinal antigen in different normal and malignant tissues was studied by indirect immunoperoxidase technique. It was shown that this antigen is characteristic for the cells of the intestinal epithelium. The antigen was revealed in 94.3% of primary and metastatic colonic tumors, 50% of gastric tumors and in all samples of the enterolysed gastric mucosa. The intestinal antigen was not found in colonic carcinoids or in the overwhelming majority of tumors of different origins.
