In genetic research, staying at the forefront of technology is crucial. The latest breakthrough in human identification comes in the form of 8-dye Short Tandem Repeat (STR) chemistry. This innovation promises unprecedented precision and accuracy in DNA analysis, revolutionizing the way we approach genetic studies. In this blog post, we’ll delve into the world of 8-color chemistry and explore how it seamlessly integrates with the game-changing Spectrum Compact CE System.
Understanding 8-Dye STR Chemistry
The introduction of 8-dye chemistry expands the capability of STR analysis, enabling researchers to analyze more DNA markers with smaller amplicons, providing more robust data from degraded or inhibited DNA samples. The performance of the 8-color dye chemistries from Promega on the Spectrum Compact CE System is sensitive, with both chemsitries (PowerPlex® 35 GY System and the upcoming PowerPlex® 18 E System) producing 100% profiles from their suggested inputs down to as little as 62.5 pg of DNA. The 18E system produced 100% profiles down to 31.25 pg of input DNA with minimal signal bleed through and low system noise.

Analytical thresholds were determined for the PowerPlex® 35GY System using average noice + 10 SD for each dye channel. All bleedthrough peaks >1% on two instruments (n = 16 per instrument) were qualified. No bleedthrough peaks >3% were observed. The average bleedthrough was ,1.4% and the maximum bleedthrough was 2.5%.
