摘要
以肝细胞癌单克隆抗体HAb18为载体,应用间接交流方法及氯胺T法,将131I和抗癌药物阿霉素(ADM)连接到HAb18上,制备出“双弹头”肝癌免疫导向药物131I─HAb18─ADM,其标记率为85%,比放射性为7.73×l04Bq/μg(1.98μCi/μg),免疫结合率为43.5%。细胞毒实验结果显示,131I─HAb18─ADM对靶肿瘤细胞SMMC─7721的杀伤效果明显强于HAb18─ADM、HAb18─131I、AMD。131I─HAb18─ADM具有选择性的高效杀伤作用,它集中了化疗与内放射治疗的优点,互相补充,展示了肿瘤导向治疗的光明前景。
Using the monoclonal antibody of hepatocellular carcinoma HAb1 8 as cariers,131I-HAb18- Adriamycin (ADM) was prepared indirectly conjugated with dextran T-40 and chloramin-T method. The rate of its immunocombine power was 43.5%.131I-HAb18-ADM showed stronger selective in vitro cytotoxicity against the target tumor cells as compared with HAb18,131I-HAB18 conjugates etc. 131I─HAb18-ADM has both the advantage of chemotherapy and internal radiotherapy,it suggests that this congugate has a better effect for tumor targetting therapy.
