OneTaq DNA Polymerase is an optimized blend of Taq and Deep VentR™ DNA polymerases for use with routine and difficult PCR experiments. The 3´→ 5´ exonuclease activity of Deep Vent DNA Polymerase increases the fidelity and robust amplification of Taq DNA Polymerase ref. The OneTaq Reaction Buffers and High GC Enhancer have been formulated for robust yields with minimal optimization, regardless of a template’s GC content.
OneTaq 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, the OneTaq High GC Enhancer can be added at a final concentration of 10–20% to reactions containing OneTaq GC Reaction Buffer.
- Ideal for routine, AT- and GC-rich PCR

Quality Control AssaysThe following Quality Control Tests are performed on each new lot and meet the specifications designated for the product. Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page.
- PCR Amplification (Buffer Dependent, GC-rich) :
The polymerase is tested in a polymerase chain reaction (PCR) using a GC-rich control template and specific primers, resulting in the buffer-dependent production of the expected product
- PCR Amplification (Enhancer Dependent, GC-rich):
The polymerase is tested in a polymerase chain reaction (PCR) using a GC-rich control template and specific primers, resulting in the enhancer-dependent production of the expected product.
- PCR Amplification (Master Mix):
The polymerase is tested in a polymerase chain reaction (PCR) using a control template and specific primers, resulting in the expected product.
