The preparation of one-step kit for the 99mTc labelled galactosyl-neo-glycoalbumin (NGA) using SnCl2 reduced method was reported in this paper. We developed a method of quality control and established the optimum scheme of technetium labelling on the basis of exploring the effects of varied labelled conditions on radiochemical purity. Our data indicates : (a) the kit is sterile, pyrogen-free and no toxic effects; (b) the operation is simple and fast; (c) its period of validity lasts no less than 3 months; (d) the radiochemical purity > 95%; (e) the stability of 99mTc-NGA in vitro > 4 hours; (f) the results of animal imaging and clinical probation are satisfactory.
本文报道了采用氯化亚锡还原法制备99mTc标记的半乳糖基新糖白蛋白（NGA）一步法试剂盒。我们开发了一种质量控制方法，并在探索不同标记条件对放射化学纯度影响的基础上，建立了锝标记的最佳方案。我们的数据表明：（a）该试剂盒无菌、无热原且无毒性作用；（b）操作简单快捷；（c）其有效期不少于3个月；（d）放射化学纯度>95%；（e）99mTc-NGA在体外的稳定性>4小时；（f）动物成像和临床试用结果令人满意。
