Promega’s Paradyme System Reduces Forensic DNA Stutter Artifacts by 8-Fold
Event summary
- Promega launched the Paradyme™ 27GY STR System, the first STR kit with Reduced-Stutter Polymerase (RSP), reducing stutter artifacts by 8-fold.
- The system simplifies mixture deconvolution, improving confidence in number-of-contributors (NoC) determination and minor contributor detection.
- Paradyme™ 27GY STR System is designed for use with Spectrum CE System and Spectrum Compact CE System.
- Promega first unveiled the novel engineered enzyme at the International Symposium on Human Identification in 2024.
The big picture
Promega’s Paradyme™ 27GY STR System addresses a long-standing challenge in forensic DNA analysis by significantly reducing stutter artifacts. This innovation could streamline mixture interpretation, reduce backlogs, and enhance the accuracy of forensic casework. The system’s compatibility with existing Promega instrumentation positions it as a potential standard in forensic labs, aligning with broader industry trends toward higher precision and efficiency in DNA analysis.
