在仓鼠中生长的GW-39人结肠癌的实验表明,注射针对结肠直肠特异性肿瘤相关抗原CSAp的放射性抗体,与先前使用癌胚抗原(CEA)放射性抗体观察到的结果相比,肿瘤放射性定位更好。然而,两种放射性抗体的混合物导致CEA-肿瘤放射免疫检测增强,而不影响CSAp-肿瘤放射定位。因此,多标记抗体混合物可能是癌症放射免疫检测的首选方法。
Experiments with the GW‐39 human colonic carcinoma growing in hamsters showed that injection of radioactive antibody to a colorectal‐specific, tumor‐associated antigen, CSAp, results in better tumor radiolocalization than was seen previously with radioantibodies to carcinoembryonic antigen (CEA). However, a mixture of both radioactive antibodies resulted in potentiation of CEA‐tumor radioimmunodetection without affecting CSAp‐tumor radiolocalization. Hence, multi‐marker antibody mixtures may be the method of choice in cancer radioimmunodetection.
