Q5® High-Fidelity PCR KitProduct information
Fidelity at its finest
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 DNA Polymerase results in ultra-low error rates. Q5 DNA Polymerase is composed of a novel polymerase that is fused to the processivity-enhancing Sso7d DNA binding domain, improving speed, fidelity and reliability of performance.
- Highest fidelity amplification (~280X higher than Taq)
- Ultra-low error rates
- Superior performance for a broad range of amplicons (from high AT to high GC)
- Hot Start and Master Mix formats available
Q5® High-Fidelity DNA Polymerase is an ultra 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 Q5
High-Fidelity 2X Master Mix offers robust, high-fidelity performance in a
convenient master mix format. 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 MgCl2.
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.
This kit contains a sufficient supply of master mix and nuclease-free water to perform 50 polymerase chain reactions (NEB #E0555S) or 200 reactions (NEB #E0555L). For added convenience, gel loading dye, and a Quick-Load DNA LAdder are also included in this kit.
The following reagents are supplied with this product:

|Gel Loading Dye, Purple (6X)||25||6 X|
|Q5® High-Fidelity 2X Master Mix||-20||2 X|
|Quick-Load® Purple 1 kb Plus DNA Ladder||4|
