MONOCLONAL ANTIBODIES REACTIVE WITH HUMAN MAMMARY AND COLON CARCINOMA CELLS

这些研究涉及到单克隆的产生和利用

These studies involve the generation and utilization of monoclonal antibodies (MAbs) to identify and characterize human carcinoma associated antigens and differentiation antigens of mammary and colonic epithelium. These MAbs are being used to better understand the cell biology and pathogenesis of human carcinomas, and to provide reagents for use in several aspects of the management of human carcinomas. These include: detection of occult tumor cells; further defining the degree of differentiation of "normal", dysplastic, and carcinoma cell populations; serum antigens assays; and radiologicalization of primary and metastatic carcinoma lesions in situ (and potentially therapy) using radiolabeled monoclonal immunolesions in situ (and potentially therapy) using radiolabeled monoclonal immunoglobulins and fragments. These studies are divided into four areas of investigation: (I) The generation and characterization of an MAb that defines a novel tumor associated antigen (TAG-72): (II) The development and characterization of MAbs to a repertoire of epitopes on carcinoembryonic antigen (CEA) which are differentially expressed among carcinoma cell population; (III) The generation and characterization of MAbs to proteins associated with metastatic cell populations, and (IV) The definition and characterization of breast and colon differentiation antigens.
