Premium-Taq polymerase provides utmost specific amplification by a dual system; antibody-mediated hot start polymerase and PMT (Polymerase Modulator on Temperature)-applied buffer. Anti-Taq antibody inhibits the Taq polymerase activity until it reaches to denaturation temperature and PMT-applied buffer reduces the primer-dimer formation and nonspecific amplification during the PCR cycles. The 5x reaction mix supplied together contains pH-buffering agent, salts, magnesium, dNTPs, and PMT additive.
Application
- Antibody-mediated Hot-start PCR
- High specific amplification and minimize the primer dimer formation
- Fast PCR assays with a short enzyme activation time and fast cycling
- Multiplex PCR
- PCR for molecular diagnostics
Figure 1. Comparison of Premium-Taq polymerase with other company’s hot start versions of DNA polymerases. 12 different primer sets designed from human genome were used in this PCR. PCR was performed using 10 ng of human genomic DNA under various annealing temperature. A : NanoHelix, B : Company I[Korea], C : Company I[USA], D : Company T[Japan].
Figure 2. Superior performance of Premium-Taq polymerase on difficult targets. Different primer sets (ApoE, MD, Prion, COMT) designed from the indicated region of human genome were used in this PCR. PCRs were performed using 10 ng of human genomic DNA. All of the DNA polymerases are hot-start versions of each brands.
