Hot Start Taq DNA Polymerase

Hot Start Taq DNA Polymerase is a recombinant, thermostable Taq DNA polymerase complexed with a thermolabile, neutralizing antibody that blocks the polymerase activity prior to the initial DNA denaturation step of PCR. When the temperature of the PCR reaction mix reaches 95°C during the initial DNA denaturing step of PCR cycling, activity of the Taq DNA polymerase is fully restored.

Description

Hot Start Taq DNA Polymerase is a recombinant, thermostable Taq DNA polymerase complexed with a thermolabile, neutralizing antibody that blocks the polymerase activity prior to the initial DNA denaturation step of PCR. When the temperature of the PCR reaction mix reaches 95°C during the initial DNA denaturing step of PCR cycling, activity of the Taq DNA polymerase is fully restored.

Key Features Enhanced specificity of amplification
Reduced primer-dimer formation
Increased yield of the PCR products

Hot Start Taq DNA Polymerase

The primer extension assay to detect the blocking activity of Taq Antibody.
To test the blocking activity of Hot Start Taq antibody, a primer extension assay was done as follows. A pair of primers was designed with a 14 bp overlap. One is 24 bp and the other one is 41 bp. The primers were annealed and incubated with Taq DNA polymerase (lane 1-2) or Hot Start Taq DNA polymerase (lane 3-4) for 0.5 h at 65℃. The extension result was separated on an Urea PAGE gel. No primer dimers were observed with Hot Start Taq polymerase. »

The PCR specificity detection of Hot Start Taq DNA polymerase.
To test the specificity of amplification, a 500 bp long HPRT fragment was amplified from human genomic DNA using Hot Start Taq DNA polymerase (lanes 1-2) and Taq DNA polymerase (lane 3-4). No non-specific bands were observed in the amplification reaction with the Hot Start Taq DNA polymerase. »
