Phusion® High-Fidelity DNA Polymerase | NEB (2024)

HomeProductsPhusion^® High-Fidelity DNA Polymerase

• Product Information

  High-Fidelity DNA Polymerases are important for applications in which the DNA sequence needs to be correct after amplification. Its unique structure, a novel Pyrococcus-like enzyme fused with a processivity-enhancing domain, increases fidelity and speed. Phusion DNA Polymerase is an ideal choice for cloning and can be used for long or difficult amplicons. With an error rate > 50-fold lower than that of Taq DNA Polymerase and 6-fold lower than that of Pyrococcus furiosus DNA Polymerase (1), Phusion is one of the most accurate thermostable polymerases available. Phusion DNA Polymerase possesses 5´→ 3´ polymerase activity, 3´→ 5´ exonuclease activity and will generate blunt-ended products.

  Phusion DNA Polymerase is supplied with standard 5X Phusion HF Buffer, as well as 5X Phusion GC Buffer, which can be used for complex or GC-rich templates. Each of these buffers contains MgCl₂ (1.5 mM at the final [1X] reaction concentration). Reactions can also be optimized using the provided DMSO or MgCl₂ solutions.
