摘要： 通过对传统的双向电泳方法进行改进与优化,得到了一种适合于分析植物叶
片蛋白质的双向电泳新方法。用改进后的方法对水稻不同时期成熟叶片蛋白质进行双向电泳分离,结果显示其稳定性和重复性好,分辨率较高,经考马斯亮蓝染色后可分辨出300多个蛋白质(肽)点。它们的等电点和分子量主要分布于pI4.1-8.2和10-100kDa之间。本文还就实验过程中出现的一些技术问题进行了讨论。
Abstract:Base on the method of O farrell,an improved procedure for the two-dimensional gel electrophoresis of leaf proteins is presented.The two-dimensional separation of proteins from the mature leaves of different developmental stages of rice provides distinct and steady results.The detected protein(peptide)spots stained by Coomassie brilliant blue R-250 are more than 300,with isoelectric points(pI)ranging from 4.1 to 8.2 and molecular weights(MW)from 10 kDa to 100 kDa.
