Description

Intact Genomics (IG) i7 Hot Start High-Fidelity DNA Polymerase is a genetically engineered, heat stable DNA polymerase which has 5´→3´ polymerase and 3´→5´ exonuclease (proofreading) activities. i7 Hot Start High-Fidelity DNA Polymerase is chemically modified that leads to complete inactivation of the polymerase until the initial heat activation step at the start of PCR. Hot start PCR reduces non-specific amplification during setup stages of the reaction and helps increase PCR specificity and sensitivity. This enzyme has the high-fidelity, sensitivity and processivity with an error rate ~2.8×102-fold lower than Taq DNA polymerase, and significantly lower than the error rates of other proofreading enzymes in the marketplace (1). i7 Hot Start High-Fidelity DNA Polymerase is ideal for cloning and can be used for long (up to 20kb) or difficult amplicons. This product is supplied with the Intact Genomics proprietary 5x PCR reaction buffer containing MgCl2 with a final (1x) concentration of 2 mM, and 5x magic enhancer that enables efficient amplification of GC rich templates up to 84%.

Activity data
i7 Hot Start High-Fidelity DNA Polymerase generates robust and high-quality PCR products with difficult templates (Fig. A).  PCR extension temperatures can be used between 68 to 72º C (Fig. B). This enzyme is resistant to different PCR inhibitors such as heparin, humic acid and xylan (Fig. C).Hot Start High Fidelity DNA Polymerase I7 image PCR difficult template
