• Testing included species specificity, sensitivity, stability, precision, reproducibility, and repeatability.
• Analysis of case-type samples, concordance, stutter, DNA mixtures, and PCR-based procedures.
• Evaluation of both extracted DNA and direct amplification from various substrates.

Main Results:

• The study generated data on all key performance parameters.
• Results demonstrated concordance with existing STR database standards.
• Performance was assessed on Applied Biosystems 3500 and 3130 Genetic Analyzers.
• Data confirmed the system's capability for direct amplification.

Conclusions:

• The PowerPlex® Fusion 6C System is validated for forensic applications.
• The system demonstrates robust performance across various forensic scenarios.
