Concentration : 5units/µl Supplied with: 10X Hibuffer A with KCl, 10X Hibuffer S with Ammonium sulphate. Ammonium sulphate allows for PCR at wide range of Mg2+ concentrations and decrease unspecific priming] Hi-Proof DNA Polymerase is an extremely thermostable polymerase from the hyperthermophilicarchaeum Pyrococcusfuriosus. Hi-Proof DNA Polymerase catalyzes the polymerization of nucleotides into duplex DNA in the 5’ to 3’ direction in the presence of Mg2+. It exhibits the 3’ to 5’ exonuclease (Proofreading) activity that enables the polymerase to correct nucleotide incorporation errors resulting in over 10-fold higher fidelity than possible with Taq DNA Polymerases. It has no 5’>3’ exonuclease activity.
