Extremely thermostable proofreading DNA polymerase blend, formulated for efficient site-directed mutagenesis and synthesis of DNA products up to 20 kb.

The enzyme is supplemented with two inert gel tracking dyes.

Unit Definition: One unit is defined as the amount of enzyme required to catalyze the incorporation of 10 nmoles of dNTP into acid-insoluble material in 30 min at 74°C. The reaction conditions are: 50 mM Tris-HCl (pH 9.0 at 25oC), 50 mM NaCl, 5 mM MgCl2, 200 μM each of dATP, dCTP, dGTP, dTTP (a mix of unlabeled and [3H]dTTP), 10 μg activated calf thymus DNA and 0.1 mg/ml BSA in a final volume of 50 μl.

Storage Conditions: Store at -20°C.

Use of Color PfuPlus! DNA Polymerase offers several advantages: 

  • visualizes the addition of the polymerase to the reaction,
  • confirms complete mixing,
  • enables direct loading of PCR products onto an agarose gel without addition of a gel loading buffer,,
  • the added dyes allow to track electrophoresis progress,
  • do not affect PCR performance,
  • do not interfere with most downstream applications (exeption: the polymerase is not recommended for any downstream application using absorbance or fluorescence excitation

Description:

  • PfuPlus! is a modified and optimized hyperthermophilic Pfu DNA Polymerase (1) blended with thermostable polymerase-enhancing factor.
  • Ultrapure recombinant enzyme.
  • The enzyme catalyzes the polymerization of nucleotides into duplex DNA in the 5'->3' direction in the presence of magnesium ions.
  • The enzyme exhibits the 3'->5' proofreading activity, resulting in over 10-fold higher PCR fidelity than possible with Taq DNA Polymerases (2).
  • The constituent of PfuPlus! DNA Polymerase, the polymerase-enhancing factor, enhances PCR product yields and increases target length capability of Pfu DNA Polymerase.
  • Enhanced performance of PfuPlus! DNA Polymerase allows to use fewer PCR cycles and lower DNA template concentrations when compared to Pfu DNA Polymerase.
  • Color PfuPlus! DNA Polymerase is recommended for use in high-fidelity PCR, PCR of GC-rich sequences or problematic secondary structures, site-directed mutagenesis and cloning of blunt-ended PCR products.
  • The enzyme is also recommended for general use in PCR and primer extension reactions at elevated temperatures to obtain a wide range of PCR products up to 20 kb.

Storage Buffer: 50 mM Tris-HCl (pH 8.0 at 22oC), 0.1 mM EDTA, 1 mM dithiothreitol, 50% glycerol and stabilizers.

10 x Reaction Buffer:

10 x Pfu Buffer: The buffer contains 20 mM MgSO4.

Quality Control: All preparations are assayed for contaminating 3'-exonuclease, and nonspecific single- and double-stranded DNase activities. Typical preparations are greater than 95% pure, as judged by SDS polyacrylamide gel electrophoresis.
