在法医物证检验中，DNA遗传标记（VN－TR、STR等）的检测成功与否将直接受到由生物检材中提取的DNA质和量的影响。人体的角化组织，特别是指甲和毛发抗腐败能力明显优于其他软组织。在腐败尸体的个人识别检验时，具有重要的意义。本研究就人指甲、毛发、角化上皮组织DNA成分的
In forensic evidence testing, DNA genetic markers (VN-TR, STR, etc.) the success of the test will be directly affected by biological samples extracted DNA quality and quantity. Human body keratosis organizations, especially nails and hair anti-corruption ability was significantly better than other soft tissues. It is of great significance in the personal identification of corrupt corpses. This study examined the DNA composition of human nails, hair, and keratinized epithelial tissues
