【摘要】 <正> 1975年Kǒmpf等首次发现人红细胞乙二醛酶I具有多态性,用淀粉凝胶电泳可将其分为GLOI_1-1,GLOI_2-1,GLOI_2-2三种表现型.由第6号染色体短臂2区1带2亚带（6 P212）上的一对共显性等位基因GLOI¹、GLOI²控制.对法医学亲权鉴定及个人识别有一定意义.我们采用淀粉琼脂糖混合凝胶电泳方法更多还原

【Abstract】 The 290 blood samples from Taiyuan area were detected by mixed starch/agarose gel electrophoresis. The phenotypes were 8 GIOI_1-1, 63 GLOI_2-1, 219 GLOI_2-2. The gene frequencies were: GLOI¹ 0.1362; GLOI² 0.8638. The 50 bloodstain samples on the cloth kept at room temperature for 3 weeks could be phenotypod correctly. The staining method was improved. The background of gel plank is clear. The improved method is （simple） rapid and more practical.更多还原
