DirecTaq™ DNA Polymerase


DirecTaq DNA polymerase saves time and cost by enabling direct PCR amplification of unpurified templates. DirecTaq DNA polymerase is a recombinant, truncated (lacks 5’ to 3’ exonuclease activity), highly thermostable DNA polymerase from the thermophilic bacterium Thermus aquaticus. The enzyme is thermostable up to 98 °C for polymerase chain reaction assays. It is supplied with 4 M betaine to improve amplification of GC-rich DNA and 30% sucrose to improve amplification from inhibitor-rich substrates such as blood.

Important note: Please be sure to use the buffer provided with this product to ensure optimal results.
