Product description
The Thermo Scientific™ Phusion™ Plus DNA Polymerase is a proofreading DNA polymerase that combines a novel Pyrococcus-like enzyme
with a processivity-enhancing domain and universal primer annealing feature. The polymerase is inactive at ambient temperatures due
to an Abody™ molecule mediated hot start mechanism, allowing reaction setup and storage of pre-assembled PCR reactions at room
temperature. Enzyme activity is restored after the initial denaturation step.
Primer annealing is performed at 60°C because proprietary additives in the reaction buer stabilize primer-template duplexes during
annealing, and eliminate the need to optimize annealing temperature for each primer pair.
The polymerase is ideal for applications where accuracy is important (cloning, sequencing, site directed mutagenesis), and possesses the
following characteristics:
• 5´→3´ DNA polymerase activity.
• 3´→5´ exonuclease activity.
• Generates blunt end amplification products.
• Amplifies up to 10 kb from genomic DNA, and 20 kb from low complexity DNA.
• Works with both AT and GC rich targets (Phusion™ GC Enhancer is provided for amplicons with >65% GC content).
• >100X fidelity compared to Taq polymerase.

General guidelines
• Use 98°C for denaturation.
• Use 15–30 s/kb for extension.
• Use 200 µM of each dNTP. Do not use dUTP (The polymerase cannot read through dUTP-derivatives or dITP in the template strand,
thus primers and dNTP mixes containing such nucleotides are not compatible).
• Carefully mix and centrifuge all tubes before opening to ensure homogeneity and improve recovery. Prepare a master mix for the
appropriate number of samples to be amplified.
• Pipette polymerase carefully and gently, as the high glycerol content (50%) in the storage buer may otherwise lead to pipetting
errors.
• Take precautions to avoid cross-contamination by using aerosol-resistant barrier tips and analyzing PCR products in a separate area
from PCR assembly.
For Research Use Only. Not for use in diagnostic procedures.
