PfuSE DNA polymerase
Cat. #E363E364
Package, u.a.2001000
Concentration, u.a./ml50005000

SourceIsolated from E.coli strain that carries recombinant plasmid containing the modified Pfu DNA Polymerase gene.
DescriptionPfuSE DNA Polymerase is improved (more stable) variant of Pfu DNA Polymerase. The enzyme catalyzes the DNA-dependent polymerization of nucleotides into DNA duplex in the 5`- 3` direction in the presence of magnesium ions. PfuSE DNA Polymerase possesses a 3`- 5` exonuclease (proof-reading) activity, that allows the polymerase to correct the nucleotide incorporation errors.
The enzyme produces DNA-products with blunt ends.
- PfuSE DNA Polymerase is useful for high fidelity synthesis and the end polishing.
Unit definitionOne unit of enzyme catalyzes the incorporation of 10 nanomoles of deoxyribonucleotides into a polynucleotide fraction (adsorbed on DE- 81) in 30 min at 72°C.
Unit Assay Conditions: 1 x PfuSE-DNA-polymerase buffer, 0.1 mg/ml BSA, 200 mg/ml activated calf thymus DNA, 0.2 mM of each dNTP, 0.4 MBq/ml [3 H]- dTTP in 50 ml reaction mix.
Reaction bufferSE-buffer PfuSE DNA polymerase+BSA
Optimal temperature
Storage conditions10 mM K2HPO4 (pH 7.4); 0.1 mM DTT; 0.1 mM EDTA; 0.5 % Tween 20; 50% glycerol. Store at -20°C.
Notes1. Do not use dU-contained templates.
2. This enzyme is not recommended for the experiments with very low-annealing temperature amplification approaches (e.g. RAPDs, Random Amplified Polymorphic DNAs).
3. Prepare PCR mix at 0°C and place it in the amplificator preheated to 95°C.
Recommended enzyme volumes to be added to the reaction mix: We recommend using 2.5 enzyme units (0.5 μl) in a final reaction volume of 50 μl.
Quality controlThe enzyme is purified free of contaminating endonucleases and exonucleases.
