单克隆抗体是特异性很强的、针对一个抗原决定簇的抗体,因此是分析和鉴定肿瘤细胞复杂抗原成分的有用工具。近来,应用单克隆抗体技术在肿瘤的诊断和治疗也出现了令人鼓舞的报告。 制备人类肿瘤抗原的单克隆抗体,一般用淋巴细胞杂交瘤技术。免疫动物所用的抗原常为体外培养 Monoclonal antibodies are highly specific antibodies to an epitope and are therefore useful tools for the analysis and identification of complex antigen components in tumor cells. Recently, there have been encouraging reports of the use of monoclonal antibody technology in the diagnosis and treatment of tumors. Monoclonal antibodies for the preparation of human tumor antigens, generally using lymphocyte hybridoma technology. Antigens used in immunized animals are often cultured in vitro
