As forensic DNA technology has become a common tool in criminal investigations, scientists have attempted to obtain DNA evidence from what were once considered unlikely sources. "Touch DNA" refers to the DNA that is left behind from skin cells when a person touches or comes into contact with an item. This present study shows, DNA profiling of touched evidence materials is reported employing a combination of LCN typing and miniSTRs. The technology is highly valuable for increasing the scope of DNA profiling to large number touched evidence materials.
随着法医DNA技术已成为刑事调查中的常用工具，科学家们试图从曾经被认为不太可能的来源获取DNA证据。“接触DNA”是指当一个人触摸或接触某一物品时，从皮肤细胞留下的DNA。本研究表明，采用低拷贝数分型和微型短串联重复序列相结合的方法，对接触过的证据材料进行DNA分析。这项技术对于将DNA分析的范围扩大到大量接触过的证据材料具有很高的价值。
