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。
Collected 20 cases of human hair (hair, pubic hair, armpit hair, legs hair) keratin components were analyzed by SDS-PAGGE. The results showed that the same individual hair keratin electrophoresis profiles are basically the same, with a laser densitometer electrophoresis gel plate scanning confirmed that the same individual hair keratin components relative percentage content was no significant difference in human head in different parts ( Top, left, right, forehead, occipital) Hair keratin electrophoretic profiles and keratin components relative percentage content is basically the same. Analysis of the same individual hair keratin can provide an important basis for personal identification of forensic evidence in hair identification.
