Pfu/Psp 2X-preMix DNA Polymerase: Datasheet Features: 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. Applications: - blunt end PCR cloning - PCR and primer extension where "high fidelity" is required - Site-directed mutagenesis - PCR where visual control is needed Description: 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) Unit definition: One unit is defined as the amount of enzyme required to catalyze the incorporation of 10 nM of dNTPs into acid insoluble material in 30 minutes at 75°C. Quality control: - Tested for the DNA amplification of 2,2 kb from lambda DNA - Contamination level check of bacterial DNA - Purity by SDS-Page > 90 % Usage: Standard protocol: - Do not use dUTP or dITP or primers containing these nucleotides
Note: - vortex all solutions carefully before using - dispense all reagents on ice to avoid degradation of primers and dNTP's - add the enzyme after Template DNA - may you have to optimize the Mg+ concentration for best result General Thermo-Cycler protocol:
Loading on the gel: Recommended volume is 10 µl of reaction mixture Storage: at -20°C for 24 months Transportation: on blue ice
