【摘要】 采用二硫苏糖醇还原ＩｇＧ，研制成９９ｍＴｃ－ＩｇＧ一步法药盒，并与配体交换二步法标记进行对比。该药盒稳定性好，标记率＞９５％，无菌、无热源。实验性金黄色葡萄球菌或松节油脓肿的家兔γ－显象表明９９ｍＴｃ－ＩｇＧ在脓肿部位浓聚。更多还原

【Abstract】 The preparation of one-step kit for the 99mTc labeled human IgG with dithiothreitol reduction and a comparison of the one-step method with the ligand exchange method were reported,The stability was good,and labeling efficiency was over 95%. The sterility and free pyrogen in the kits were demonstrated. The scintigraphy imaging in the rabbits with staphylococcus aureus or turpentine-induced abscesses showed accumlation of 99mTc-IgG in the abscesses.更多还原
