Important Tips for Working with Q5 DNA Polymerase

Q5® High-Fidelity DNA Polymerase is 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 > 100-fold lower than that of Taq DNA Polymerase and 12-fold lower than that of Pyrococcus furiosus (Pfu) DNA Polymerase, Q5 High-Fidelity DNA Polymerase is ideal for cloning and can be used for long or difficult amplicons.Q5 High-Fidelity DNA Polymerase is supplied with an optimized buffer system that allows robust amplification regardless of GC content. The 5X Q5 Reaction Buffer contains 2 mM MgCl2 at final (1X) reaction concentrations and is recommended for most routine applications.For GC-rich targets (≥ 65% GC), amplification can be improved by the addition of the 5X Q5 High GC Enhancer. Q5 High-Fidelity DNA Polymerase is unlike typical, lower fidelity PCR enzymes.Q5® High-Fidelity DNA Polymerase Applications: High-fidelity PCR Cloning Long or Difficult Amplification High-throughput PCR
