i7 High-Fidelity DNA Polymerase
i7® High-Fidelity DNA Polymerase 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.
Intact Genomics (IG) i7® High-Fidelity DNA Polymerase is a genetically engineered, heat stable DNA polymerase which has 5´→3´ polymerase and 3´→5´ exonuclease (proofreading) activities. 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® 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 2.5x i7® PCR reaction buffer containing MgCl2 with a final (1x) concentration of 2 mM. This buffer allows for amplification of non GC rich templates and of GC rich templates up to 84%.
The physical purity of this enzyme is ≥98% as assessed by SDS-PAGE with Coomassie® blue staining.
E. coli strain expressing genetically engineered i7® High-Fidelity DNA Polymerase gene.
We have tested i7® High-Fidelity DNA Polymerase activity with λ DNA and other difficult templates for PCR amplification up to 20kb. Intact Genomics (IG) i7® high-fidelity DNA Polymerase generates robust and high-quality PCR products in comparison with other high-fidelity DNA polymerases available in the marketplace.
