Pfu/Psp DNA Polymerase 2X Pre-Mix (ready-to-use)

Pfu DNA polymerase 2X-preMix is a convenient Mixture of proof-reading Enzyme, reaction buffer dNTP´s and MgCl2. It generated PCR fragments exhibits the lowest error rate of any thermostable DNA polymerases. The fragements are blunt-ended for direct ligation


Pfu/Psp DNA polymerase replicates DNA at 75°C catalyzing the polymerization of nucleotides into duplex DNA in the 5´→3´ direction in the presence of Mg+. Pfu DNA polymerase possesses 3′ to 5′ exonuclease proof reading activity that enables the polymerase to correct nucleotide-misincorporation errors. To reduce the risk of contamination, pipetting errors and to increase the repeatable of results the 2X-preMix contains an optimized mixture of enzyme, dNTP’s and reaction buffer. Just add your template DNA and primers.

– blunt end PCR cloning
– PCR and primer extension where “high fidelity” is required
– Site-directed mutagenesis
– PCR where visual control is needed

Pfu/Psp DNA polymerase 2X-preMix is isolated from the archae bacteria Pyrococcus f-species, a thermostable Polymerase of approximately 90000 daltons.  Base misinsertions that may occur during polymerization are rapidly excised by the proofreading activity of the polymerase. The Pfu/Psp DNA Polymerase has no detectable reverse transcriptase activity.

Concentration: Premix 2X (25µl per reaction)
