Q5® High-Fidelity 2X Master Mix
cloned at NEB recombinant No hifi pcr 3

Fidelity at its finest – for over 10 years

Product Introduction

Q5® High-Fidelity DNA Polymerase sets a new standard for both fidelity and robust performance. With the highest fidelity amplification available (~280 times higher than Taq), Q5 results in ultra-low error rates. Q5 is composed of a novel polymerase that is fused to the processivity-enhancing Sso7d DNA binding domain, improving speed, fidelity and reliability of performance.

Product Information

Description

 

The Q5 High-Fidelity 2X Master Mix offers robust, high-fidelity performance in a convenient master mix format. The Q5 High- Fidelity 2X Master Mix features a high-fidelity, thermostable DNA polymerase with 3´→ 5´ exonuclease activity, fused to a processivity-enhancing Sso7d domain to support robust DNA amplification. With an error rate ~280-fold lower than that of Taq DNA Polymerase, Q5 High-Fidelity DNA Polymerase is ideal for cloning and can be used for long or difficult amplicons. The convenient master mix formulation is supplied at a 2X concentration. The mix contains dNTPs, Mg++ and a proprietary broad-use buffer requiring only the addition of primers and DNA template for robust amplification regardless of GC content. When used at the recommended 1X final concentration, the Q5 High-Fidelity Master Mix contains 2 mM Mg++. Q5 High-Fidelity DNA Polymerase is unlike typical, lower fidelity PCR enzymes. To determine the optimal annealing temperatures for a given set of primers, use of the NEB Tm Calculator is highly recommended.

Q5-High Fidelity 2X Master Mix formats allow robust amplification of a broad range of targets with a single formulation.

Product Notes

  1. A precipitate (most noticeable after the first 1–2 freeze/thaw cycles) is not uncommon. To ensure optimal performance, the master mix should be thawed and resuspended prior to use. Stability testing using up to 15 freeze/thaw cycles has shown no negative effect on master mix performance.

  2. Product specifications for individual components in the Q5 High-Fidelity 2X Master Mix are available separately.
