TaqNovaHS Polymerase is a mixture of thermostable Taq DNA polymerase isolated from Thermus aquaticus and a highly specific monoclonal antibody, which acts as an inhibitor of the polymerization activity. The TaqNovaHS enables easy set-up of a hot-start PCR reaction at room temperature. The antibody binds reversibly to the enzyme, inhibiting polymerase activity at ambient temperatures, which prevents extension of non-specifically annealed primers and primer-dimers formed at low temperatures during PCR setup. The antibody is released from the polymerase during normal cycling conditions. The use of the TaqNovaHS Polymerase does not require any additional incubation step to activate the enzyme.
It is recommended for a wide range of demanding applications, which require highly specific amplification. The TaqNovaHS polymerase is a universal and easy-to-use DNA polymerase which works rapidly and effectively in various PCR conditions. The enzyme catalyses DNA synthesis in a 5’ → 3’ direction, shows no 3′ → 5’ exonuclease activity, but has a 5’ → 3’ exonuclease activity.
