The AccuPower PyroHotStart Taq PCR PreMix is a PCR master mix containing a thermostable DNA polymerase, thermostable pyrophosphatase, reaction buffer, dNTPs, tracking dye, and patented stabilizer in a ready to use hotstart PCR master mix.
Gentaur uses a unique enzyme-mediated HotStart PCR system that provides robust, sensitive and reliable results.
Gentaur's Taq DNA Polymerase is inhibited at lower temperatures (< 70°C) by pyrophosphate. This prevents the formation of mis-primed products and primer-dimers during the reaction set up process resulting in improved PCR specificity. However, Taq DNA Polymerase is rendered fully active at temperatures above 70°C via pyrophosphate hydrolysis with a thermostable pyrophosphatase (Figure 1). AccuPower® PyroHotStart Taq PCR PreMix is ideal for nucleic acid amplification reactions involving complex genomic or cDNA templates, very low copy targets, and multiplex reactions.

Figure 1. Comparison of PCR amplification specificity between AccuPower® PyroHotStart Taq PCR PreMix from Gentaur and other suppliers' Hot start PCR master mix.
PCR reactions were performed according to each supplier's protocol. The PrP gene was amplified from human genomic DNA with two different primer sets, separately. This data shows that AccuPower® PyroHotStart Taq PCR PreMix has higher amplification efficiency and specificity than other suppliers' Hot start PCR master mix.
