DYS570

PowerPlex® Fusion 6C System High Sensitivity = More Information at Low DNA Input 3 Y-STR’s = Better Determination of Male Contributors (1 Male : 1 Male : 20 Female Mixture; 1ng Total; 29 cycles)

23 Autosomal STR’s + 3 Y-STR’s + Amelogenin = High Discriminatory Power

Direct Amp + Fast Cycling + 12.5µl Reaction Volume = Improved Lab Efficiency

• Error bars in top panel show the standard deviation of the mean from triplicate amplification reactions.

• All amplification reactions were performed using a GeneAmp® PCR System 9700 thermal cycler

• One μl of amplified products was separated on an Applied Biosystems® 3500 Genetic Analyzer (1.2kV, 15-second injection).
