２－巯基乙胺作抗体还原剂，利用自行配制的亚锡葡萄糖酸钠及亚锡焦磷酸钠冷冻药盒进行抗体（人血两种球蛋白）直接标记，并对用这两种药盒所得标记产物的质量控制进行了初步研究．同时，比较了用２－巯基乙醇及亚甲基二磷酸盐（ＭＤＰ）药盒标记产物的性能．体外实验结果表明，使用本方法所得标记产物的标记率高（＞９７％），可在体外稳定存放．我们尝试将所得标记产物用于家兔炎症模型的显像，效果较好． 2-mercaptoethylamine as an antibody reducing agent, using a self-formulated sodium stannous gluconate and sodium tin pyrophosphate freezing kit antibody (human blood two globulin) direct labeling, and the use of these two kits obtained The quality control of the labeled product was preliminary studied. In the meantime, the performance of labeling products with 2-mercaptoethanol and methylene diphosphate (MDP) kits was compared. The results of in vitro experiments show that the labeled products obtained by this method have high labeling rate (> 97%) and can be stably stored in vitro. We tried to use the resulting labeled product for the imaging of rabbit inflammatory model, the effect is better.
