Common questions
Why does ESSplex SE QS include DYS391 alongside the autosomal loci?+
DYS391 is a Y-chromosome marker included to help resolve male DNA in mixtures with female contributors, giving analysts extra discrimination in cases such as sexual assault where autosomal loci alone can be ambiguous.
Why is this kit tied specifically to the European Standard Set?+
The European Standard Set is the fixed panel of loci EU member states agreed to share for cross-border Prum database searching, so a kit built around it produces profiles directly comparable across national databases without extra loci conversion.
What does the QS in the kit name typically indicate for this product line?+
QS variants in Qiagen STR kits add internal quantification and quality sensor loci that flag degraded or inhibited samples during the same amplification run, rather than requiring a separate quantification step beforehand.
