The PowerPlex® 21 System is a multiplex STR system for human identification applications including forensic analysis, relationship testing and research use. The system allows co-amplification and fluorescent detection of 21 loci (20 STR loci and Amelogenin), including D1S1656, D2S1338, D3S1358, D5S818, D6S1043, D7S820, D8S1179, D12S391, D13S317, D16S539, D18S51, D19S433, D21S11, Amelogenin, CSF1PO, FGA, Penta D, Penta E, TH01, TPOX and vWA. The system offers high discrimination with 21 markers for difficult cases and complete data overlap with most existing multiplexes.
The PowerPlex® 21 System increases laboratory productivity and decreases average turnaround time with 90-minute PCR. Laboratories can also save labor and time since the wash step for FTA® cards is eliminated. Simpler protocols are available for swabs and nonFTA card punches as well. The higher inhibitor tolerance of this system benefits challenging casework samples and results in less locus drop-out and reaction failure for higher success rates.
