HiFi DNA Polymerase

HiFi DNA Polymerase
HiFi DNA polymerase is ideal for amplification of DNA fragments that require
high-fidelity. High fidelity is achieved by an optimal blend of high performance
YEAtaq DNA polymerase and Accu DNA polymerase, a Pyrococcus proofreading
(3'→5' exonuclease activity ) enzyme. This formulation achieves greater yields
with higher fidelity than standard DNA polymerases such as Taq. HiFi is a
quality choice for sensitive applications. Because of the presence of Accu DNA
polymerase in the blend, dUTP, dITP and primers containing these nucleotides
should not be used in PCR because they hinder DNA synthesis.
HiFi DNA polymerase is offered in two different packages, one with dNTPs mix
and the other without. HiFi DNA Polymerase is also available in 2× ready-to-use
premix format with a green dye.
• Robust amplification with minimal optimization.
• High yields of PCR products.
• Higher sensitivity compared to conventional Taq DNA Polymerase.
• Amplification of long targets up to 6 kb from genomic DNA.
• Generates 3’-dA overhangs.
• Incorporates modified nucleotides.
• The error rate of HiFi DNA Polymerase in PCR is 8.3×10-6 errors per nucleotide
per cycle.
• Cloning and expression
• Blunt end amplification products
• Mutation analysis
• Efficient & highly sensitive PCR use
• Routine PCR amplification of DNA fragments up to 6 kb from genomic DNA
Unit Definition
One unit is defined as the amount of enzyme that will incorporate 10 nmol of
dNTPs into acid-insoluble material in 30 minutes at 72 °C.
Quality Control
• Nuclease activity is not detected after incubation of 1 μg λ/Hind III DNA with
5 units of HiFi DNA polymerase in 50 μl reaction buffer for 18 hours at 37 °C.
• The absence of endo-, exodeoxyribonucleases and ribonucleases is confirmed
by appropriate tests. Functional test is performed by PCR.
