AccuPower DualStar qPCR PreMix is a lyophilized PCR master mix containing a thermostable DNA polymerase, thermostable pyrophosphatase, reaction buffer, dNTPs, tracking dye, and patented stabilizer in a ready to use hotstart qPCR master mix.
DualStar qPCR PreMix eliminates nonspecific reaction, while providing high sensitivity, due to our novel HotStart methodology. Gentaur uses a unique enzyme-mediated HotStart PCR that provides robust and reproducible results. Gentaur’s Top DNA Polymerase is inhibited at lower temperatures (< 70°C) by pyrophosphate. However, Top DNA Polymerase is rendered fully active at temperatures above 70°C via pyrophosphate hydrolysis with our thermostable pyrophosphatase. This prevents the formation of mis-primed products and primer-dimers during the reaction set up process resulting in improved PCR specificity. It is ideal for nucleic acid amplification reactions involving complex genomic or cDNA templates, very low copy targets, and multiplex reactions.
DualStar Plus qPCR PreMix goes a step further by providing resistance to common inhibitors of PCR (Blood-EDTA, Hemoglobin, Humic Acid from various sources, etc.) providing you with robust and reliable results, even with poor quality samples. Tested for resistance against many common inhibitors of PCR, DualStar plus is the enzyme of choice for any PCR that you want to work right – the first time and every time!
