OneTaq® Hot Start DNA Polymerase is an optimized blend of Taq and Deep Vent® 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.The inhibitor binds reversibly, blocking polymerase activity at temperatures below 45°C. The polymerase is activated during normal cycling conditions, allowing reactions to be set up at room temperature. OneTaq Hot Start DNA Polymerase does not require a separate high temperature incubation step to activate the enzyme and can be used in typical Taq-based cycling protocols.
OneTaq Hot Start DNA Polymerase is supplied with two 5X buffers: (Standard and GC), as well as a High GC Enhancer solution. For most routine and/or AT-rich amplicons (Lambda, etc.) or complex amplicons with up to ~65% GC content, OneTaq Standard Reaction Buffer provides robust amplification. For GC-rich amplicons, the OneTaq GC Reaction Buffer can improve both performance and yield. For particularly high GC or difficult amplicons (i.e. ≥ 75% GC), the OneTaq High GC Enhancer can be added at a final concentration of 10–20% to reactions containing OneTaq GC Reaction Buffer.
Comparison of OneTaq Products to Other Commercially Available Polymerases
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.
