Looking for standard Taq?
abm offers Taq DNA Polymerase (Cat. No. G009) and Taq 2X PCR MasterMix (Cat. No. G888) for affordable routine PCR.

MegaFi™ Fidelity DNA Polymerase

MegaFi™ Fidelity DNA Polymerase is the best high fidelity DNA Polymerase on the market. With 1300X better fidelity than regular Taq, this ultrasensitive polymerase amplifies even the most difficult templates.

1300X higher fidelity than Taq

Amplifies difficult templates

Effective in long-range PCR

Ultra-Low Error Rates

MegaFi™ DNA Polymerase is THE BEST high fidelity DNA polymerase. A lacZa-containing sequence was amplified using various DNA polymerases, subcloned, and plated on X-gal-containing media. Colonies without PCR amplified lacZa mutations appear dark blue, while those that have PCR introduced frameshift mutations appear white.

Superior Fidelity

MegaFi™ DNA Polymerase has ~1300X higher fidelity than other enzymes on the market. abm’s MegaFi™ Fidelity DNA Polymerase (Cat. No. G896) has the highest accuracy rate compared to other DNA polymerases as tested using blue/white colony screening. Shown as relative fidelity compared to Taq DNA Polymerase (Taq = 1X). PCR cycle number and mutations resulting in non-phenotypic changes are accounted for.

BlasTaq™ DNA Polymerase

Blast through a routine 2 hour PCR run in only 20 minutes with our BlasTaq™ DNA Polymerase. Reach extension speeds as fast as 6 kb/min and streamline your PCR!

6 kb/min extension speed

40-70% less time than Taq

Superior sensitivity

Super Fast Extension Speeds

BlasTaq™ DNA Polymerase enables extension speeds as fast as 6 kb/min. Total reaction times for abm’s BlasTaq™ DNA Polymerase (Cat. No. G894) and Taq were determined for the amplification of different sized amplicons: 500 bp, 1 kb, 2 kb, and 5 kb. Reaction times are based on a 30-cycle program using the recommended reaction protocol for each enzyme.

Highly Robust

PCR amplification using abm’s BlasTaq™ DNA Polymerase (Cat. No. G894) (column 1) of various targets vs. competitor polymerases (column 2 and 3) followed by electrophoresis on a 1% agarose gel. A) 1 kb target from Human cDNA. B) 1.3 kb target from plasmid DNA. C) 7.6 kb target from plasmid DNA.

BlasTaq™ HotStart DNA Polymerase

Eliminate non-specific amplification and primer-dimer formation with our next generation BlasTaq™ HotStart DNA Polymerase. This formulation includes a proprietary antibody that blocks polymerase activity at low temperatures and dissociates at the denaturation step to restore enzyme activity.

No non-specific amplification or primer dimers

Improves yield of desired product

Simplifies reaction setup

Excellent for suspension cells

BlasTaq™ HotStart DNA Polymerase eliminates non-specific amplification. abm ’s BlasTaq™ HotStart DNA Polymerase (Cat. No. G595) was used to amplify a 7 kb target. The antibody concentration was decreased incrementally from lanes 1-5. Lane 1 is our BlasTaq™ HotStart formulation and lane 5 contains no antibody.

Super Fast Extension Speeds

BlasTaq™ HotStart DNA Polymerase has extension speeds of 6 kb/min. abm ’s BlasTaq™ HotStart DNA Polymerase (Cat. No. G595) was used to amplify different sized amplicons (500 bp, 1 kb, 2 kb, and 5 kb). Total reaction times are listed based on a 30-cycle program using the recommended reaction protocol for each enzyme.
