摘要
降解生物检材遗传标记的检测一直是法医学实践和科研的难点。虽然PCR-STR分析技术能在一定程度上检测降解生物检材的遗传标记,但是对于某些高度降解的生物检材如骨骼、牙齿等的PCR-STR分型仍旧十分困难,存在不稳定性和分型异常现象。本文就近几年来PCR-STR分型技术在降解生物检材的法医实践中出现的问题和解决方法作一综述。
It＇s always a challenge to type from highly degraded biological remains. PCR-based STR genotyping is helpful and valuable for such degraded samples like bones, teeth et al, but the typing results are sometimes unstable or wrong. Here the methods for solving the problems and improving reproducibility are reviewed.
