Y-STR Kit Evaluations
Participants: John M. Butler, Amy E. Decker, Peter M. Vallone
Project Timeframe: June 2002 to August 2004
Purpose: As part of developing a new STR kit, prior to its release, commercial manufacturers have supplied us with kit materials for evaluation purposes.
Progress: We evaluated Y-PLEX 5 (ReliaGene), Y-PLEX 12 (ReliaGene), PowerPlex Y (Promega), and Yfiler (Applied Biosystems) Y-STR DNA test kits prior to their release to the general human identity testing community. In the case of ReliaGene, we helped establish nomenclature of alleles and evaluate balance of amplification products (Note: sales of these kits were discontinued by ReliaGene after May 2005 due to patent licensing issues). Early evaluation of the PowerPlex Y kit was for the purpose of examining the SRM 2395 materials to aid with allele nomenclature confirmation. With the Yfiler kit, we performed a set of requested beta-test experiments and conducted a study with our set of U.S. population samples. These data are available at http://www.cstl.nist.gov/biotech/strbase/NISTpopdata/YfilerNISTdata.xls and are part of the Yfiler Haplotype Database: http://www.appliedbiosystems.com/yfilerdatabase/.
