Anti-Taq high is a highly purified neutralization monoclonal antibody to Taq DNA polymerase. This product provides an antibody-mediated hot start PCR to enhance the specificity and sensitivity of PCR. This antibody inhibits polymerase activity before the onset of thermal cycling, preventing primer dimer formation and non-specific amplification. At the first denaturation step of the thermal cycling, the antibody is quickly inactivated and PCR proceeds. The antibody-mediated hot start method is significantly more convenient to use than other hot start methods.


  • Inhibits ≥95% polymerase activity at 45ºC
  • No contamination of mouse genomic DNA examined by PCR
  • Enhances the specificity and sensitivity of PCR
  • Can be used when other hot start methods are difficult to perform (e.g. capillary PCR)
  • The polymerase can be reactivated quicker than with methods utilizing a chemically modified polymerase


  • Antibody-mediated hot start PCR

Example 1.Application of the hot start PCR using the Taq based high efficient PCR enzyme

The efficiency of anti-Taq antibodies were evaluated by the amplification of the human β-globin gene (3.6 kb).

The result indicates that anti-Taq high increases the specificity and sensitivity of the PCR compared with the control reaction and PCR mediated hot start using company A's anti-Taq antibody.
