某些灵长类毛发角蛋白的等电聚焦分析

ANALYSIS OF SOME PRIMATE KERATINS BY ISOELECTRIC FOCUSING

本文用聚丙烯酰胺凝胶等电聚焦(PAGIEF)对分属灵长类的5个科的15种动物毛发角蛋白进行了分析,并用激光光密度计对PAGIEF板进行了扫描。结果表明,各种灵长类毛发角蛋白的PAGIEF谱型均有差异。因此,本方法可以用于灵长类动物之间毛发角蛋白组分的鉴别。

The keratins in hair have been analysed by polyacrylamide gel isoelectric focusing from 15 species of Primates, including the species Homo sapiens. In all patterns obtained from these primate hairs, the bands are different from each species to any other in number or position, or both. The gel scans of keratins given by a laser light densitometer show differences between species as well. The isoelectric focusing of keratins in hair would prove to be useful in identifying hair from human and other primates.
