Real-time quantitative PCR (qPCR) has generated a great deal of interest in the forensic DNA typing community in the past several years as this technique can rapidly detect low levels of DNA with minimum hands-on time and minor sample consumption. The ability to utilize human specific assays in U.S. crime laboratories is important in order to meet federally mandated requirements (DAB/FBI Standard 9.3) to assess the quantity of human DNA in casework samples, particularly where bacterial contamination may exist.
