Taq Polymerase purified from an E. coli strain carrying a plasmid with Taq DNA polymerase gene from Thermus aquaticus YT-1.
Description: Taq DNA Polymerase is a thermostable enzyme that catalyses 5’→3′ synthesis of DNA. The enzyme has no 3’→5’ proofreading exonuclease activity but possesses low 5’→3′ exonuclease activity.
Unit definition: One unit is defined as the amount of enzyme required to catalyse the incorporation of 10 nmoles of dNTPs into acid insoluble material in 30 minutes at 72 °C.
Assay conditions: The polymerase activity was assayed in 10 mM Tris-HCl (pH 8.5 at 25 °C), 50mM KCl, 1.5 mM MgCl2, 200 µM each of dATP, dGTP, dCTP, dTTP (a mix of unlabelled and [3H] dTTP) and 12.5 µg activated calf thymus DNA, in a final volume of 50 µL.
Storage buffer: 100 mM NaCl, 50 mM Tris-HCl (pH 8.0 at 25 °C), 1mM DTT, 0.1 mM EDTA, 1% Triton X-100 and 50% Glycerol.
Taq DNA polymerase buffer: 50 mM KCl, 10 mM Tris-HCl (pH 8.5 at 25 °C) 1.5 mM MgCl2, 0.1 % Triton X-100.
Our Taq DNA Polymerase was extensively functionally tested and carefully tested for absence of endo- and exodeoxyribonucleases.
