DreamTaq DNA Polymerase

DreamTaq DNA Polymerase
Enhanced Taq DNA polymerase optimized for all standard PCR applications ensuring higher sensitivity, longer PCR products and higher yields.

Thermo Scientific DreamTaq DNA Polymerase is an enhanced Taq DNA polymerase optimized for all standard PCR applications. It ensures higher sensitivity, longer PCR products and higher yields compared to conventional Taq DNA polymerase. DreamTaq DNA Polymerase uses the same reaction set-up and cycling conditions as conventional Taq DNA polymerase. Extensive optimization of reaction conditions is not required. It is supplied with optimized DreamTaq buffer, which includes 20 mM MgCl2.

DreamTaq PCR Master Mix (2X) is a ready-to-use solution containing DreamTaq DNA Polymerase, optimized DreamTaq buffer, MgCl2, and dNTPs. This pre-mixed formulation saves time and reduces contamination due to the fewer pipetting steps required for PCR set up. The master mix retains all features of DreamTaq DNA Polymerase. It is capable of robust amplification of up to 6 kb from genomic DNA and up to 20 kb from viral DNA.
