Description 

The 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. 

Features

  • 5’→3’ DNA polymerase activity 

  • 3’→5’ exonuclease (proofreading) activity 

  • 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
