Quick High Fidelity DNA Polymerase, Q-HiFi DNA Polymerase (Cat# TF2000). 1U/ul, 100U/Pack

Our quick high fidelity DNA polymerase, Q-HiFi™ DNA Polymerase (TF2000) is a unique blended enzyme mix containing a high fidelity DNA polymerase and an elongation enhancer, thus being capable to perform quick and accurate PCR. The extension rate of Q-HiFi™ DNA Polymerase (7 sec/kb) is > 4-fold quicker than that of pfu DNA polymerase (30 sec/kb). The fidelity of Q-HiFi™ DNA Polymerase is 50 times higher than that of Taq DNA polymerase. The optimized 5X Q-HiFi™ Buffer includes special enhancers that contribute to suppress non-specific amplification as well as plateau effect produced by conventional PCR. Therefore, fast fidelity Q-HiFi™ DNA Polymerase exhibits great elongation capability (up to 40 kb from lambda DNA).

•5’→3’ DNA polymerase activity
•3’→5’ exonuclease (proofreading) activity
•High reaction rate: 7 seconds/kb
•High fidelity: 50 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. Q-HiFiTM DNA Polymerase’s high processability enables reliable amplification of λDNA up to 40 kb in length (M: DM3100 ).


Fig. 2. Q-HiFiTM DNA Polymerase can amplify PCR products from as little as 1 fg of template DNA (M: DM2000).

Long range PCR amplification for next-generation DNA sequencing
Generates blunt end amplicons for cloning with GetClone™ PCR cloning vector
