OneTaq® Hot Start DNA Polymerase is an optimized blend of Taq and Deep VentR™ DNA polymerases combined with an aptamer-based inhibitor. The 3´→ 5´ exonuclease activity of Deep Vent DNA Polymerase increases the fidelity and robust amplification of Taq DNA Polymerase (1) and the hot start formulation combines convenience with decreased interference from primer dimers and secondary products. The OneTaq Reaction Buffers and High GC Enhancer have been formulated for robust yields with minimal optimization, regardless of a template’s GC content.
