Description
Taq DNA Polymerase(a) is a thermostable enzyme of approximately 94 kDa isolated from Thermus aquaticus. This unmodified enzyme replicates DNA at 74¡ãC and exhibits a half-life of 40 minutes at 95¡ãC. The enzyme catalyzes the polymerization of nucleotides into duplex DNA in the 5?~3? direction in the presence of magnesium and also possesses a 5?~3? exonuclease activity. Taq DNA Polymerase is recommended for use in PCR but is not recommended for use in DNA sequencing reactions.

Source
Recombinant e.coli contains Thermus aquaticus polymerase gene.
Storage Buffer
Compatibility with Reaction Buffers: Taq DNA Polymerase in Storage Buffer. Use of other reaction buffers that do not contain Triton X-100 (final concentration of 0.1%) will result in inactivation of the enzyme.
50mM Tris-HCl (pH 8.0), 100mM NaCl, 0.1mM EDTA, 1mM DTT, 50% glycerol and 1% Triton X-100.
Storage Conditions
Stable for 5 days at 10¡ãC, for longer period of time store at -20¡ãC.
Synonyms
DNA polymerase I thermostable, EC 2.7.7.7, Taq polymerase 1.
Unit Definition
