New England Biolab Ltd Phusion Hot Start Flex DNA Polymerase 500 units 

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, Phusion is one of the most accurate thermostable polymerases available. Phusion DNA Polymerase possesses 5' to 3' polymerase activity, 3' to 5' exonuclease activity and will generate blunt-ended products. 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.
