Product Information

Description

OneTaq® Hot Start 2X Master Mix with GC Buffer is an optimized blend of Taq and Deep Vent® DNA Polymerases combined with an aptamer-based inhibitor. This enzyme blend is ideally suited to PCR applications from GC-rich templates, including pure DNA solutions, bacterial colonies and cDNA products. The 3´→5´ exonuclease activity of Deep Vent DNA Polymerase increases the fidelity and robust amplification of Taq DNA Polymerase (1). The hot start nature of the enzyme offers convenience with decreased interference from primer dimers and secondary products. The convenient master mix formulation contains dNTPs, MgSO4, buffer components and stabilizers, requiring only the addition of primers and DNA template for robust amplification.

Comparison of OneTaq Products to Other Commercially Available Polymerases

OneTaq_ComparisonChart_0220 
Amplification of a selection of high GC human genomic DNA targets demonstrates OneTaq performance. All polymerases were cycled according to manufacturer’s recommendations, including the use of additives to enhance the amplification of targets with high GC content. Yield (dot size) and purity (color) of reaction product were quantified from triplicate reactions on a Perkin Elmer LabChip®. A large, dark green dot represents the highest yield and purity.
