摘要： 用SDS -PAGGE对收集到的 2 0例人体表毛发 (头发、阴毛、腋毛、腿毛 )角蛋白组分进行了分析。结果表明 ,同一个体毛发角蛋白电泳谱型基本相同 ,用激光光密度仪对电泳凝胶板扫描后证实 ,同一个体毛发角蛋白组分相对百分含量也无明显差异 ;人头部不同部位 (顶部、左侧、右侧、额部、枕部 )头发角蛋白的电泳谱型和角蛋白组分相对百分含量也基本相同。同一个体毛发角蛋白组分的分析 ,可为法医物证学鉴定中的毛发个人识别提供重要的依据。

Abstract: Keratin contents of different hairs from the head, pubic, armpit and leg of one individual were analyzed by SDS-PAGGE Samples were collected from 20 individuals The results showed that the electrophoretic patterns of different body hairs of the same individual were almost identical The relative contents of keratin composition from the same individual were tested by Laser Densimetic Scanning No obvious difference was found Electrophoretic keratin patterns and relative keratin contents of head hairs from different parts (crown, left side, right side, forehead and occiput) of the same individual were observed No obvious difference was found It is concluded the analysis of electrophoretic keratin pattern of human body hairs can be used as an important evidence for forensic individual identification

Key words: SDS-PAGGE, body hair(s), keratin, electrophoretic pattern
