AccuPower TLA PCR PreMix is a high fidelity PCR master mix that contains an easy to resuspend lyophilized mix of TLADNA Polymerase, dNTPs, reaction buffer, tracking dye, and patented stabilizer conveniently packaged in individual tubes or plates. Simply add template, primers and water. The TLA DNA Polymerase in the premix is a cloned and modified derivative isolated from Thermococcus onnurineus NA1 and features a proofreading activity, an enhanced processivity, and robust amplification efficiency compared to Pfu DNA polymerase or Vent DNA polymerase. These features allow high fidelity DNA amplification as well as long range PCR up to 20 kb.
AccuPower TLA PreMix high fidelity PCR master mix is available with or without loading dye. When loading dye is present you can load it directly into your gel after PCR – no glycerol or glucose is required.
