Standard PCR Enzyme
Code No. TAP-201 250U
Taq DNA polymerase is the most widely used thermostable DNA polymerase derived from the thermophilic bacteria Thermus aquaticus (Taq) YT-1. The enzyme possesses a 5’→3’ polymerase activity and a double-strand specific 5’→ 3’ exonuclease activity.
E. coli strain carrying the cloned Taq DNA polymerase gene from Thermus aquaticus (Taq) YT-1.
One unit is defined as the amount of enzyme that will incorporate 10 nmoles of dNTP into an acid insoluble material in 30 min at 75ºC.
20 mM Tris-HCl (pH 8.0), 100 mM KCl, 0.1 mM EDTA, 0.5% Nonidet™ P-40, 0.5% Tween™ 20, 50% Glycerol.
