【摘要】 对取食过无色杆菌毒蛋白的菜蛾幼虫血淋巴进行酯酶同工酶聚丙烯酰胺电泳分析,与对照相比,酯酶酶谱发生变化,酶活力降低.经胶条扫描分析,在主酶带区,对照吸光度为处理组的3～12倍更多还原

【Abstract】 The esterase of hemolymph of the larvae of Plutella xylostella fed on Plpt was analysed by polyacrylamide gel electrophoresis(PAGE).In contrast to the larvae without being fed on Plpt,the zymogram changed and activity of esterase decreased.Through the gel scan, the ABS of zymogram of the larvae without being fed on Plpt in the main zymogram band,were 3～12 times as much as those fed on Plpt.更多还原
