摘要

全基因组扩增(Whole genome amplification, WGA)技术是一种对全部基因组序列进行非选择性扩增的技术。近几年来, 对 WGA技术扩增痕量DNA检材的研究日渐深入, 这些研究可望用于刑案现场采集到的痕量DNA样品的扩增, 为法医个体识别提供足量的DNA模板。然而, 对实际案件中复杂检材的扩增偏差问题一直困扰着法医工作者, 寻求一个低扩增偏差、高扩增产率的WGA技术是法医工作者的主要目标。文章综述了WGA技术在法医个体识别中的研究进展及应用前景, 为法医解决扩增偏差问题提供参考。

Abstract

Whole genome amplification (WGA) is a technique that could non-selectively amplify the genomic DNA. In recent years, intensive studies have been made on application of WGA in trace DNA amplification, which might be applied to amplify trace DNA collected from crime scenes and provide enough DNA templates for forensic individual identification. However, the problem of amplification bias happened in the complicated test materials from real crime scenes is still troublesome. Development of WGA method with low amplification bias and high yield is the main target of current forensic research. Here, we reviewed the advances and the application prospect of WGA in individual identification. This might provide a reference for solving the problem of the amplification bias.
