上海第二医学院附属瑞金医院、上海化学试剂研究所、上海第一医学院红旗药厂应用放射免疫探测法定位诊断甲胎蛋白分泌性肿瘤获得成功。其诊断原理是利用标记的抗体对肿瘤靶抗原特异的亲和力,使其在肿瘤部位聚集,并与周围正常组织产生放射性强度差,取得定位诊断。方法:治患者注射碘标记抗甲胎蛋白抗 Ruijin Hospital Affiliated to Shanghai Second Medical College, Shanghai Institute of Chemical Reagent, Hongqi Pharmaceutical Factory, Shanghai First Medical College successfully applied radioimmunoassay to diagnose alphafetoprotein secreting tumors. The diagnostic principle is the use of labeled antibodies on the specific affinity of the tumor target antigen, so that it gathered in the tumor site, and with the surrounding normal tissue produce radioactive intensity difference, to obtain the positioning diagnosis. Methods: Patients were treated with iodine-labeled anti-alpha fetoprotein
