STR Analysis

The PowerPlex® 16 HS System offers an improved multiplex for the analysis of 15 STR markers and Amelogenin. Using the same primers as the PowerPlex 16 System, this assay adds a hot start enzyme to the buffer for room-temperature set-up and less pipetting. Additionally, a new buffer increases amplification success rates with high levels of PCR inhibitor.
