人体肿瘤常能产生与癌有关的癌胚蛋白,后者已广用作肿瘤标志,而由这些蛋白形成的抗体已成功地应用于癌的免疫测定,因此,这些抗体有可能作为药物的良好载体,而将抗癌药导向产生这些抗原的癌细胞。本文报道用柔红霉素-抗癌胚抗原免疫球蛋白轭合物(Con-jugate)对能产生癌胚抗原(CEA)的人体结肠癌细胞的体外实验结果。 Human tumors often produce cancer-associated oncofetal proteins, which have been widely used as tumor markers. Antibodies formed from these proteins have been successfully used in cancer immunoassays. Therefore, these antibodies may serve as good carriers of drugs. Instead, cancer drugs are directed to cancer cells that produce these antigens. This article reports the results of in vitro experiments on human colon cancer cells that produce carcinoembryonic antigen (CEA) using the daunorubicin-anti-carcinoembryonic antigen immunoglobulin conjugate (Con-jugate).
