作者对自制的~(125)I-HCG的生物活性作了受体亲和力、靶组织专一性及受体对标记物的有限结合能力等试验,结果表明:~(125)I-HCG具有良好的生物活性。根据受体-配体结合理论及本研究结果,提出了测试~(125)I-HCG生物活性的4个可行指标。
The authors tested the biological activity of homemade 125 I-HCG for receptor affinity, target tissue specificity, and receptor limited binding ability to the label. The results show that: (125) I-HCG has good Biological activity. According to the receptor-ligand binding theory and the results of this study, four feasible indexes for testing the bioactivity of ~ (125) I-HCG were proposed.
