CEQ Series and GenomeLab GeXP genetic analysis systems, is used to determine the purity and quality of DNA for sample tracking and contamination monitoring. It is offered for users working with large numbers of DNA samples in applications such as clinical trials, tissue culture facilities and core labs. Loci known to be problematic have been excluded from the primer set. The set is provided in a vial containing 12 primer pairs to amplify 11 STR loci and one gender-determining locus. Each vial requires no preparation and contains reagents for 48 reactions.
