摘要
对番茄种子芽期过氧化物酶(POD)同工酶与酯酶(EST)同工酶聚丙烯酰胺凝胶电泳(PAGE)方法进行了初步研究。结果表明,POD同工酶电泳酶样提取液以pH6.5~7.5的0.1.mol/L磷酸缓冲液十0.1%巯基乙醇较适宜;EST同工酶酶样提取液以pH6.0~70的0.1mol/LTris-柠檬酸+0.1%巯基乙醇或0.1mol/L磷酸缓冲液+0.1%巯基乙醇较适宜。常用的7.5%分离胶浓度不适宜番茄种子芽期POD和EST同工酶电泳分析,采用11.5%的分离胶能达到理想的分离效果。
Study on PAGE method of POD and EST isozyme in tomato germinating seeds was carriedout, the results indicated that the suitable extraction buffer for POD isozyme is pH6. 5~7- 5 0. 1 mol/Lphosphate buffer+0. 1 % mercaptoethanol, and that for EST isozyme is pH 6. 0~7. 0 0. 1 mol/L Triscltrate +0. 1% mercaptoethanol or 0. 1 mol/L phosphate buffer + 0. 1 mol/L mercaptoethanol. The7. 5% separating gel concentratlon was not suitable for both lsozymes in question, it should be replacedwith 11. 5% concentration in order to achieve satisfactory electrophoresis effect.
