The Q5 Quick-Load High-Fidelity 2X Master Mix offers high-fidelity performance in a convenient master mix format. The master mix features Q5, a high-fidelity, thermostable DNA polymerase with 3´to 5´ exonuclease activity fused to a processivity-enhancing Sso7d domain. With an error rate ~280-fold lower than that of Taq DNA Polymerase, Q5 offers highly accurate amplification and can be used to amplify difficult or long targets (up to 20 kb for simple templates). The master mix includes polymerase, dNTPs, Mg++, and two commonly used tracking dyes for easy and direct loading of PCR products onto gels. On a 1% agarose gel in 1X TBE, Xylene Cyanol FF migrates at ~3-5 kb and Tartrazine migrates at ~50 bp. The broad-use buffer requires only the addition of primers and DNA template for robust amplification, regardless of GC content.

To determine the optimal annealing temperature for a given set of primers, use of the NEB Tm Calculator is highly recommended.

For flexibility, standalone Q5 polymerase products and the included High GC Enhancer can support amplification of targets with differing amounts of GC content. For convenience, and to amplify a broad range of target GC content, Q5 master mixes are recommended.

Figure 2: Migration of tracking dyes contained in Quick-Load® PCR reagents during electrophoresis

Green visible tracking dye with Quick-Load® separates to blue ~ 3-5 kb and yellow ~ 50 bp
Quick-Load PCR reagents enable direct loading of PCR products onto agarose DNA gels for analysis. Quick-Load amplification products deliver the same performance as their non-Quick-Load equivalents, while incorporating two PCR-inert tracking dyes for enhanced visualization. During gel electrophoresis, the blue Xylene Cyanol FF dye co-migrates with DNA fragments of approximately 3-5 kb in a 1% agarose gel, while the yellow Tartrazine dye migrates at approximately 50 bp for clear monitoring of both large and small DNA fragments. Additionally, the combination of the blue and yellow dyes results in a green reagent that enables visual tracking of reaction set up.
