A research team from Lawrence Livermore National Laboratory in California have revealed an identification method using a subject's hair protein.The scientists believe they could use protein markers from a small number of human hairs, possibly as little as one, to distinguish an individual among the world's population.”We are in a very similar place with protein-based identification to where DNA profiling was during the early days of its development,” said LLNL chemist Brad Hart, the director of the Lab's Forensic Science Center and co-author of a paper detailing the work.”This method will be a game-changer for forensics, and while we've made a lot of progress toward proving it, there are steps to go before this new technique will be able to reach its full potential.”The work of LLNL scientists, a researcher with Utah-based Protein-Based Identification Technologies, LLC and other collaborators is described in a paper published today in PLOS ONE ,. a San Francisco-based peer reviewed online scientific journal.The team's collaborators and advisers include researchers from seven universities – Utah Valley University, the University of Utah, Montana State University, the University of California, Davis, the University of Bradford in the United Kingdom, George Mason University and the University of Washington.In the PLOS ONE study, the researchers examined male and female hair samples for 66 European-Americans, five African Americans, five Kenyans and six skeletal remains from the 1750s and 1850s, finding a total of 185 protein markers so far. Each person's number of hair protein markers, combined with their pattern of protein markers, is unique.
