Concordance Study on Population Database Samples Using the PowerPlex™ 16 Kit and AmpFℓSTR® Profiler Plus™ Kit and AmpFℓSTR® COfiler™ Kit

Abstract Over 500 population database samples comprising African Americans, Bahamians, and Southwestern Hispanics were typed using the PowerPlex™ 16 and the Profiler Plus™ COfiler™ kits. There was only one sample in which a typing difference was observed. An FGA heterozygote profile was observed using the PowerPlex™ 16 primers, and a single allele FGA profile was observed using Profiler Plus primers. Thus, the extant data suggest that the primers used in the PowerPlex™ 16, Profiler Plus™, and COfiler™ kits are reliable for typing reference samples destined for use in CODIS. In 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 estimating the rarity of a multiple loci profile consisting of these two and the 13 core STR loci.
