Created by the same team that created STRmix, FaSTR DNA expedites the analysis of raw data generated by … Michigan State Police Forensic Science Division 3 Purpose: This work validates the use of the software application STRMixTM as a probabilistic genotyping tool to assist in the interpretation of DNA testing profiles from Promega’s PowerPlex® Fusion STR amplification chemistry at 30 cycles using an Applied Biosystems 3500/3500XL capillary STRmix™ Version 2.8 features a top-down approach that allows users to set the number of major contributors to a mixed DNA profile in which there is interest, and then obtain a likelihood ratio STRmix™ is now being routinely used to resolve DNA profiles by 36 U.S. forensic labs, including the FBI and the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). STRMix: Probabilistic Genotyping Mixture Deconvolution The use of probabilistic genotyping enables Bode’s analysts to develop more profiles in cases that previously too complex to analyze. By using this technology, we can: Generate more useable profiles Deliver more investigative information Interpret previously unresolvable mixtures STRMix - Implementation Bode has validated To date, STRmix™, key part of the total workflow incorporating DBLR™, has been used to interpret DNA evidence in more than 220,000 cases worldwide. That number includes numerous U.S. court cases and more than 80 successful admissibility hearings. Since its introduction eight years ago, STRmix™ has been used to interpret DNA evidence in more than 160,000 cases worldwide.
