Generating STR profile from “Touch DNA”

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.
