High GC High Fidelity DNA Polymerase, High GC DNA Template DNA Polymerase (Cat# TF3000). 1U/ul, 100U/Pack

The High GC High Fidelity DNA Polymerase, G-HiFi™ DNA Polymerase is a new genetically modified, recombinant DNA polymerase suitable for GC-rich templates that are difficult to amplify. The fidelity of G-HiFi™ DNA Polymerase is 70 times higher than that of Taq DNA polymerase. The high extension rate of G-HiFi™ DNA Polymerase is achieved by blending the DNA polymerase with an elongation enhancer. The optimized 5X G-HiFi™ Buffer includes special ingredients that suppress non-specific amplification as well as plateau effect produced by conventional PCR. With the optimized 5X G-HiFi™ Buffer, G-HiFi™ DNA Polymerase is capable to amplify most templates, such as longer targets (up to 40 kb from lambda DNA) and that contain GC-rich sequences.

• 5’→3’ DNA polymerase activity
• 3’→5’ exonuclease (proofreading) activity
• Suitable for GC-rich templates
• High reaction rate: 7 seconds/kb
• High fidelity: 70 times higher than Taq polymerase
• Generates blunt end amplicons
• Vast elongation capability (up to 40 kb)
• Thermo-stable for more than 10 hrs at 95°C.


Fig. 1. G-HiFiTM DNA Polymerase’s high processability enables reliable amplification of λDNA up to 40 kb in length (M: DM5100).


Fig. 2. G-HiFiTM DNA Polymerase performs higher sensitivity for high GC content templates (GC: 71%) compare to high fidelity DNA Polymerase from Brand A (M: DM2000).


  • Long range PCR amplification for next-generation DNA sequencing
  • Generates blunt end amplicons for cloning with GetClone™ PCR cloning vector
  • Amplification of GC-rich templates

Recommended Primer design
For ≦10 kb products:
For general amplification, select primers with a Tm value of ≧ 55°C. 20- to 25-mer primers are suitable, or greater than 25-mer in length may provide optimal results.
For >10 kb products:
Select primers with a Tm value of ≧ 65°C. 25- to 35-mer primers are suitable. Avoid high GC-content at the 3′ end of each primer.
