Keyword:  合浦珠母贝同工酶多态位点平均杂合度电泳;
Abstract: 采用聚丙烯酰胺梯度凝胶垂直板电泳技术和特异性染色方法,对合浦珠母贝外套膜、闭壳肌、肝脏和鳃组织中的15种同工酶系统进行分析,结果表明:a-GPDH、ADH在4种组织中均未见表达;AK、AMY、PGM、ALP、GDH和LDH只在肝脏中表达,而ME、SOD、EST、MDH、G6PD、6PGD和AAT则有较广泛的组织分布,其中12个座位(Aat-1、Aat-2、Sod-1、Sod-2、Sod-3、Sod-4、m-Mdh-c、G6pd-2、6Pgd-2、Ak-1、Gdh-1、Me-2)具有多态性,多态位点比例为46.1%,平均杂合度0.112 2±0.057 6。
