Description Taq DNA Polymerase is a thermostable recombinant DNA polymerase derived from thermophilic bacterium Thermus aquaticus. Its molecular weight is 94 kDa. Taq DNA Polymerase can amplify DNA target up to 5 kb (simple template). The elongation velocity is 0.9~1.2kb/min (70~75°C). It has 5' to 3' polymerase activity but lacks of 3' to 5' exonuclease activity that results in a 3'-dA overhangs PCR product. Unit Definition One unit is defined as the amount of the enzyme required to catalyze the incorporation of 10 nmole of dNTPs into an acid-insoluble form in 30 minutes at 70°C using hering sperm DNA as substrate. Storage Buffer 20mM TrisCl ( pH8.0), 100mM KCl, 3.2mM MgCl2 1mM DTT，0.1% Triton X-100 ,0.1% Tween20, 0.2mg/ml BSA, 50% (v/v) glycerol 10X PCR Buffer without Mg2+ 100mM Tris-HCl(PH 8.8), 500mMKCl, 1%Triton-X-100
