Description & Specifications

Specifications

Includes 2X Phusion Green Hot Start II High-Fidelity PCR Master Mix (provides 1.5 mM MgCl2 in the final 1X concentration); Water, nuclease-free; DMSO
Quantity 500 x 50μL rxns

Phusion Hot Start II High Fidelity DNA Polymerase combines the Phusion DNA Polymerase and a reversibly bound, specific Affibody ligand. Affibody inhibits the DNA polymerase activity at room temperature and thus prevents the amplification of nonspecific products.

The Affibody ligand also inhibits the 3‡→5‡ exonuclease activity of the polymerase, preventing degradation of primers and template DNA during reaction set up. At polymerization temperatures, the ligand is released, rendering the polymerase fully active. Phusion Hot Start II DNA Polymerase does not require a separate activation step in the PCR protocol as it is immediately reactivated at high temperatures.

New Phusion Green Hot Start II High-Fidelity DNA Polymerase is a combination of Phusion Hot Start II DNA Polymerase and 5X Phusion Green Buffers. The buffers include a density reagent and two tracking dyes for direct loading of PCR products on a gel. The colored buffer does not interfere with excelent performance of Phusion Hot Start II DNA Polymerase and is compatible with downstream applications such as DNA sequencing, ligation and restriction digestion.
