TF1000 ExcelTaq SMO-HiFi DNA Polymerase For Gene Cloning. 1 Units/ul, 100 Units/Pack

The ExcelTaq SMO-HiFi High Fidelity DNA Polymerase is a new genetic modified, recombinant DNA polymerase with 70 times higher fidelity during amplification than wild type Taq DNA polymerase, as well as very fast elongation rate. Being highly thermostable, the SMO-HiFi high fidelity DNA Polymerase can remain viable even after being subjected to boiling for 2 minutes. The ExcelTaq SMO-HiFi DNA Polymerase is also designed to operate in much lower Mg2+ concentration as compared to other DNA polymerase. Our high fidelity DNA polymerase is great for high GC DNA fragment amplification. SMOBIO HiFi DNA Polymerase is great for gene cloning subcloning applications.


• 5’→3′ DNA polymerase activity
• 3’→5′ exonuclease activity (proofreading)
• High reaction rate (up to 67 base/ second)
• High fidelity, 70 times of Taq polymerase
• Blunt end amplicon
• Thermo-stable-half life is more than 10 hrs at 95°C ion
