Abstract

Fusion of the murine myeloma line P3-X63-Ag8-U1 with spleen cells from a mouse immunized with a membrane preparations (CM) of a mucinous ovarian cytoadenocarcinoma yielded two monoclonal antibodies, MOv1 and MOv2, which reacted by solid-phase radioimmunoassay with immunizing tumor CM but were unreactive with normal kidney CM as well as with plasma proteins and peripheral blood cells from the immunizing carcinoma patient. MOv1 and MOv2 were further tested by solid-phase radio-immunoassay on a panel of different CM from fresh surgical specimens of ovarian and nonovarian carcinomas, benign ovarian tumors, normal ovary and kidney tissues, and on various tumor cell lines. In addition, the antibodies were characterized by immunofluorescence on live cells from cell lines and surgical specimens, and on frozen sections of benign and malignant ovarian tumors, of nonovarian tumors, and of normal tissues. The results obtained indicate that MOv1 and MOv2 recognize two different epitopes on molecules present on malignant and benign ovarian mucinous tumors and colonic glands. In addition, the antigen recognized by MOv2 was also detected in carcinomas of lung, colon, stomach, and breast; in gastrointestinal glands; and in the glandular lumina of normal lactating breast.
