摘要： <正> γ-谷氨酰转肽酶(GGT EC2,3,2,2,)存在于人体许多组织之中,它催化γ-谷氨酰基因的转移。七十年代中期,国外学者发现人类精液和阴道分泌液中存在高活性的 GGT,并具有多态性和稳定性。目前,国内尚未见有人类精液 GGT 多态性的分型报导,本文应用平板圆盘电泳技术,分析研究中国人群中精液 GGT 的多态性,现将初步研究结果报告如下。

Abstract: This paper reported the polymorphism of Seminal r-glutamyl transpeptidase(GGT)camined in 75 unrelated chinese male.Engyme typing revealed three types of band patterns was carried out for common polyacrylamide gel electrophoresis and the specific engyme staining.The frequencies of the three types were GGT1=0.19,GGT2=0.32,GGT2-1=0.49,The observed numbers of the phenotyas were in good agrcement with the numbers expected under the Hardy-Weinberg equilibrium.The Discriminating Power (DP)were estimated at 0.62.
