Phusion® Hot Start Flex DNA Polymerase
For high speed and high performance PCR. Manufactured and quality-controlled at New England Biolabs, Thermo Scientific® Phusion High-Fidelity DNA Polymerase offers both high fidelity and robust performance.
- 50X higher fidelity than Taq
- Robust reactions with minimal optimization
- Hot start formulation enables room temperature reaction setup and reduces non-specific amplification
- High yields with shorter extension times
High Fidelity DNA Polymerases are important for applications in which the DNA sequence needs to be correct after amplification. Phusion High-Fidelity DNA Polymerase offers both high fidelity and robust performance, and thus can be used for all PCR applications. 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 Hot Start Flex DNA Polymerase offers robust, high fidelity performance and room temperature reaction setup. The addition of an aptamer-based inhibitor allows room temperature reaction setup. Phusion Hot Start Flex 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.
Phusion Hot Start Flex DNA Polymerase is unlike other enzymes and care must be taken when designing cycling protocols. To determine the optimal annealing temperatures for a given set of primers, use of the CalculatormNEB T is highly recommended.
