摘　　要：本文将蒸馏水双重浸泡的方法用于等电聚焦(IEF)前血痕中Gc的提取,分别对不同条件下保存的血痕中Gc可检出时间进行了探讨,检测了-30℃保存半年和室温保存4个月的血痕,其Gc检出率为100%。37℃保存一周的血痕,85%可正确定型。并将Gc系统应用于亲子鉴定和个人识别中。A method of 'double extraction' with distill water was intrcduced to treatbloodstains before Gc typing by PAGIEF (pH 4-6) following immunofixation,and the detactable time of Gc subtypes from bloodstains kept at differentconditions was also studied. Ge subtypes were typed successfully in bloodstainskept at -30℃ for 6 months and room temperature for 4 months, but only in85% bloodstains successfully kept at 37℃ for one week. In addition, the Gcsubtypings were applied to paternity test and individual identification.
