Extraction of DNA from Hair using forensicGEM® Tissue
11 Aug 2013Hairs found at crime scenes can be important trace evidence, and in some cases are the one and only link to a suspect. As a source of DNA, hair can prove vital in forensic human identification. Nevertheless, most methods for the extraction of DNA from hair involve a lengthy process that requires extensive manual manipulation. This application note presents a quick method for the extraction of DNA from hair using ZyGEM forensicGEM® Tissue. This method has proven to be a better alternative to other, more time-consuming protocols (for example phenol-chloroform extraction).
