Promega Introduces Groundbreaking 8-Color STR Kit Approved by FBI
Promega's New 8-Color STR System Receives FBI Approval
In a significant advancement for forensic science, Promega Corporation has unveiled the PowerPlex® 35GY System, the first-ever 8-color STR analysis kit that has received approval from the FBI for the National DNA Index System (NDIS). This prestigious approval means that the product complies with the stringent Quality Assurance Standards (QAS) set by the FBI, allowing it to produce DNA profiles that are eligible for submission to the national database.
Importance of NDIS Approval
The significance of NDIS approval cannot be understated, especially for laboratories focused on databasing. Amy Gero, a Supervising Forensic Scientist at the Arizona Department of Public Safety, expressed the excitement surrounding this innovation, stating, "For a lab like ours, where databasing is a priority, the NDIS approval of the PowerPlex® 35GY System is a big win. Having a system that delivers more informative profiles means we can contribute to a more complete and reliable DNA database." This highlights the vital role that reliable DNA analysis technologies play in ongoing investigations.
Strict Validation Process
Achieving NDIS approval entails rigorous validation studies conducted by multiple labs. Labs must carry out thorough performance analyses focusing on precision, resolution, and allelic discrimination. Furthermore, the PowerPlex 35GY System had to align with the CODIS Core Loci, a set of genetic markers incorporated within the NDIS database. The initiative spearheaded by the New Hampshire State Police Forensic Laboratory was reinforced by validation support from various forensic labs across the nation, along with contributions from the Central de Criminalística de la Guardia Civil in Madrid.
8-Color STR Analysis Advantages
What sets the PowerPlex® 35GY System apart is its innovative use of eight dyes, making it the first of its kind to obtain NDIS approval. Most other commercially available kits typically use five or six color dyes for marking DNA regions. The incorporation of additional colors allows Promega to enhance the system's reliability in analyzing degraded or challenging DNA samples. Interestingly, Promega also developed the Spectrum CE System, the first capillary electrophoresis instrument built to process 8-color chemistry.
Enhanced Profile Information
According to Lotte Downey, the Senior Manager of Genetic Identity at Promega, the kit combines the 20 core loci with a distinct set of Y-STR markers. This combination not only enhances the accuracy of the analysis but also ensures that the kit performs well with degraded DNA samples. Particularly important in cases involving male suspects, such as sexual assault, this added feature provides crucial discriminatory power in forensic investigations.
Quality Assurance Standards Met
Promega takes quality seriously, ensuring that their forensic products comply with ISO 18385 standards. This standard is crucial as it minimizes the risk of human DNA contamination in products used for collecting, storing, and analyzing biological materials for forensic applications. With over 25 years of experience in developing DNA-based human identification products, Promega continues to lead in innovation.
Striving for Excellence in Forensics
As forensic technologies evolve, Promega’s dedication to quality assurance and innovation empowers laboratories worldwide to conduct more accurate and reliable DNA analyses. Their commitment to excellence reinforces the confidence that law enforcement and forensic professionals have when utilizing Promega’s products.
