MB Taq DNA Polymerase is a highly processive 5´→3´ polymerase with no 3´→5´ exonuclease (proofreading) activity. At 72 °C and around pH 9 conditions, MB Taq DNA Polymerase reaches its highest level of activity, capable of amplifying a standard 1 kb strand of DNA in approximately 30 seconds.

The Taq‘s activity is blocked at ambient temperature, e.g. while preparing your sample. The inhibition of the Taq polymerase is completely reversed when the temperature is above 70 °C. Complete activation of the polymerase is achieved at 94 °C for 2 min. MB Taq DNA Polymerase is supplied with a 10x buffer for maximal yield and sensitivity which should fit most standard applications.

Recommended Use

Routine and multiplex PCR; real-time PCR; T/A cloning; DNA labeling with biotin, digoxigenin or radioactive nucleotides; sequencing of double or single stranded DNA


MB Taq DNA Polymerase, supplied in 10 mM Tris-HCl (pH 7.0), 50 mM KCl, 0.1 mM EDTA, and 50 % (v/v) glycerol. 10x reaction buffer.
100 mM MgCl2 solution.
If the polymerase is used in combination with Venor®GeM Classic, the buffer provided with the polymerase is not required.
