单克隆抗体(McAb)为探寻肿瘤抗原提供了一种精确的工具,将已建立的肿瘤细胞系和新近分离的肿瘤细胞及其提取物或其组分,用免疫学方法已鉴定出很多肿瘤相关抗原。目前,人们已将McAb用于检测人类黑色素瘤、白血病、淋巴瘤、肉瘤、结肠癌、肺癌、乳腺癌和卵巢肿瘤等。已分离出糖蛋白抗原,糖脂抗原、糖粘蛋白抗原和粘 Monoclonal antibodies (McAbs) provide an accurate tool for the search for tumor antigens. The established tumor cell lines and newly isolated tumor cells and their extracts or their components have been identified by immunological methods for many tumors. antigen. Currently, McAb has been used to detect human melanoma, leukemia, lymphoma, sarcoma, colon cancer, lung cancer, breast cancer, and ovarian tumors. Has isolated glycoprotein antigens, glycolipid antigens, sugar mucin antigens and
