Pwo SuperYield DNA Polymerase combines the recombinant enzyme Pwo DNA Polymerase with an optimized buffer system. This buffer system enhances the enzymatic properties of the polymerase, resulting in higher yields of the amplification reaction without changing the fidelity of DNA synthesis. This enzyme delivers excellent results due to its enzyme design and optimized buffer system. It amplifies fragments up to 3 kb - even longer amplicons are possible from simple templates.
Pwo DNA Polymerase exhibits increased thermal stability with a half life of greater than 2 hours at +100 °C compared to Taq DNA Polymerase with a half life of less than 5 min at this temperature.
Pwo SuperYield DNA Polymerase, originally isolated from Pyrococcus woesei, is a processive 5′ → 3′ DNA polymerase with 3′ → 5′ exonuclease proofreading activity; 5′ → 3′ exonuclease activity is not detectable.
The enzyme accepts modified nucleotides for efficient labeling of nucleic acids by PCR.
PCR products are blunt-ended directly useable for blunt-end ligation.
Using the magnesium-containing reaction buffer supplied, the final MgCl2 concentration is 1.5 mM.
Star activity: In cases where star activity is observed and/or the activity of the enzyme in the PCR mix is low, purify the amplification product prior to the restriction enzyme digest using High Pure PCR Product Purification Kit.
Pwo SuperYield DNA Polymerase combines the recombinant enzyme Pwo DNA Polymerase with a newly optimized buffer system. Pwo SuperYield DNA Polymerase is used for the amplification of DNA with the intent to sequence the amplification product or to clone the product (e.g., for the expression of the gene product). The high fidelity of this enzyme makes it particularly suitable for:
- High fidelity PCR
- Site-directed mutagenesis
- Gene expression
- Study of allelic polymorphism in individual RNA transcripts
- Characterization of rare mutations in tissue
- Characterization of the allelic stage of single cells or single DNA molecules

1 kit containing 4 components
Each lot is assayed using activated DNA. PCR testing used λ and human genomic DNA.
One unit Pwo SuperYield DNA Polymerase is defined as the amount of enzyme that catalyzes the incorporation of 10 nmol total deoxynucleoside triphosphates into acid precipitable DNA within 30 minutes at +70 °C.
Unit Assay: Incubation buffer for assay on activated DNA
20 mM Tris-HCl, pH 8.8 (20 °C), 50 mM KCl, 2.5 mM MgCl2, 10 mM 2-mercaptoethanol, 0.2 mM of each dATP, dCTP, dGTP, dTTP.
12.5 mg activated calf thymus DNA and 0.1 mCi [α-32P]dCTP are incubated with 0.01 to 0.1 U Pwo SuperYield DNA Polymerase in 50 μl incubation buffer with a paraffin oil overlay at +70 °C for 30 minutes. The amount of incorporated dNTPs is determined by trichloroacetic acid precipitation followed by scintillation counting.
Volume Activity: 5 U/μl
