Concordance study on population database samples using the PowerPlex (TM) 16 kit and AmpFlSTR (R) Profiler Plus (TM) kit and AmpFlSTR (R) COfiler (TM) kit

Over 500 population database samples composing African Americans, Bahamians , and Southwestern Hispanics were typed using the PowerPlex (TM) 16 and the Profiler Plus (TM) COfiler (TM) kits. There was only one sample in which a typing difference was observed. An FGA heterozygote profile was observed u sing the PowerPlex (TM) 16 primers, and a single allele FGA profile was obs erved using Profiler Plus primers. Thus, the extant data suggest that the p rimers used in the PowerPlex (TM) 16, Profiler Plus (TM), and COfiler (TM) kits are reliable for typing reference samples destined for use in CODIS. I n addition, African American, Bahamian, and Southwestern Hispanic databases have been established for the STR loci Penta D and Penta E. Both loci are highly polymorphic. The application of the product rule is valid for estima ting the rarity of a multiple loci profile consisting of these two and the 13 core STR loci.
