[Analysis of electrophoretic patterns of different body hairs of the same individual].
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.
