Descrição:

Pfu Pol is a thermostable proofreading enzyme specially designed for highly accurate and efficient amplification it replicates into dsDNA at 72 °C . It catalyzes the polymerization of nucleotide in the 5' → 3' direction in the presence of magnesium and exhibits a 3' → 5' exonuclease (proofreading) activity. This features results in a greatly increased fidelity of DNA synthesis compared to Taq polymerase. The enzyme is highly purified and free of bacterial DNA. The amplification results in blunt-ended fragments.

Fidelidade da Enzima:

Pfu Pol is characterized by a 6x higher fidelity compared to Taq DNA Polymerase.

PCR Reaction Setup:

The PCR procedure below shows appropriate volumes for a single 50-μL reaction. For multiple reactions, prepare a master mix of components common to all and then dispense appropriate volumes into each PCR reaction tube prior to adding template DNA and primers. Thaw, mix, and briefly centrifuge each component before use.

Add the following components to a microcentrifuge tube:

1. Prepare PCR master mix

Note: Consider the volumes for all components listed next steps to determine the correct amount of water required to reach your final reaction volume.

Component	50 μL rxn	Final conc.
Water, grade PCR	to 50 μl	-
10x Reaction Buffer	5 μl	1x
dNTP (Mix 10 mM)	1 μl	200 μM
Pfu Pol (2,5U/ µl)	0,5 μl	1,25 U/reaction

Mix and briefly centrifuge the components.

2. Add template DNA and primers

Component	50 μl rxn	final conc.
Forward primer (10 μM)	0,5 – 2,5 μl	0,1 – 0,5 μM
Reverse primer (10 μM)	0,5 – 2,5 μl	0,1 – 0,5 μM
Template DNA	x μl	1 pg – 1 μg**

**genomic DNA: 1 ng – 1 μg; plasmidial DNA: 1 pg – 1 ng

Cap each tube, mix, and briefly centrifuge the content.

3. Incubate reactions in a thermal cycler

Recommended cycling conditions:

Initial denaturation	98 °C	30 sec	1x
Denaturation	98 °C	5 - 10 sec	25-35 cycles
Annealing**	45 - 70 °C	15 - 30 sec	25-35 cycles
Elongation***	72 °C	1 min/kb	25-35 cycles
Final extension (optional)	72 °C	1 – 2 min/kb	1x
Hold	4 – 8 °C	∞	1x

**The annealing temperature depends on the melting temperature of the primers used

***The elongation time depends on the length of the fragments to be amplified. A time of 1 min/kb is recommended.

For optimal specificity and amplification an individual optimization of the recommended parameters may be necessary for each new template DNA and/or primer pair.
