Thermo Scientific Phusion High-Fidelity DNA polymerases set a gold standard for high performance PCR. Featuring an error rate 50-fold lower than that of Taq and 6-fold lower than that of Pfu, Phusion High-Fidelity DNA Polymerase is excellent choice for cloning and other applications requiring high fidelity. Phusion DNA polymerases offer robust performance with short protocol times, even in the presence of PCR inhibitors, and generate higher yields with lower enzyme amounts than other DNA polymerase.
With Phusion Hot Start II High-Fidelity DNA Polymerase amplification proceeds without the production of nonspecific products due to the combination of Phusion DNA Polymerase and a reversibly bound, specific Affibody ligand that inhibits DNA polymerase activity at room temperature. The Affibody ligand also inhibits the 3' to 5' exonuclease activity of the polymerase, thus preventing degradation of primers and template DNA during reaction set up. At temperatures that promote polymerase activity, the ligand is released, rendering the polymerase fully active. Phusion Hot Start II DNA Polymerase is immediately reactivated at high temperatures, so it does not require a separate activation step in PCR protocols.
Phusion Hot Start II High-Fidelity DNA Polymerase is a combination of Phusion Hot Start II DNA Polymerase and the 5X Phusion buffers. The buffers include a density reagent and two tracking dyes which do not interfere with the robust performance of Phusion Hot Start II DNA Polymerase. Researchers may directly load PCR products on a gel making this a versatile option for use in downstream applications such as DNA sequencing, ligation and restriction digestion.
