Thermo Fisher Scientific's Simple Red DNA Polymerase incorporates an inert red dye for error-free pipetting and easier reaction set up. As a recombinant enzyme, it also offers higher purity for increased performance and greater reproducibility in polymerase chain reactions (PCR).
Simpler Red is a recombinant Taq DNA polymerase expressed in E. coli. The recombinant enzyme is shown to have equivalent activity and specificity compared with native Taq, but offers higher purity and greater stability. Simpler Red is thus able to offer improved overall PCR performance.
The inert red dye allows the enzyme to be easily visualised, providing immediate confirmation of accurate pipetting, without affecting reaction performance.
