牛血小板衍化生长因子等电点的分析

Isoelectric focusing analysis of bovine platelet-derived Cgrowth factor

目的：测定分析牛血小板衍化生长因子的等电点。方法；用薄层聚丙烯酰胺凝胶等电聚焦的方法。结果：牛血小板衍化生长因子的等电点为９．６～１０．０。结论：牛血小板衍化生长因子是一种强碱性蛋白质，即强阳离子多肽，可能含有相对较多的碱性氨基酸。

Aim: The isoelectric point (pI) of bovine platelet-derived growth factor was determined. Methods: Isoelectric focusing in polyacylamide gels was used. Results: The isoelectic point of bovine platelet-derived growth factor was 9.6～10.0. Conclusions: Bovine platelet-derived growth factor is strongly basic protein and may contain the strong predominance of basic amio acids in its amio acid composition.
