Maxima™ Hot Start DNA polymerase is designed to enhance the specificity, sensitivity and
yield of DNA amplification. In addition, the enzyme provides the convenience of reaction set-
up at room temperature. Maxima™ Hot Start DNA polymerase is a recombinant DNA
polymerase which has been chemically modified by the addition of heat-labile blocking groups
to its amino acid residues. The enzyme is inactive at room temperature, avoiding extension of
non specifically annealed primers or primer dimers and providing higher specificity of DNA
amplification. The functional activity of the enzyme is restored during a short 4-minute
incubation at 95 °C. The activated enzyme maintains the same functionality as DNA
polymerase: catalyses 5’→3’ synthesis of DNA, has no detectable 3’→5’ proofreading exonuclease activity, but possesses low 5’→3’
exonuclease activity. It exhibits deoxynucleotidyl transferase activity, which adds extra adenines at the 3’-end of PCR products. Before
activation, these two activities are not detectable. Applications include Hot Start PCR, high yield amplification of targets up to 3 kb from
genomic DNA and up to 5 kb from viral DNA, RT-PCR, highly specific amplification of complex genomic and cDNA templates, amplification of
low copy DNA targets, qPCR, multiplex PCR, and generation of PCR products for TA cloning.
Phire® Hot Start II DNA polymerase is faster, extremely robust, and capable of amplifying long DNA fragments with high yields. Phire® Hot
Start II DNA polymerase incorporates a dsDNA-binding domain which allows short extension times (10 to 15 s/kb), improves yields, and
increases fidelity 2-fold compared to
Taq
DNA polymerase. In addition, the Hot Start technology allows complete reactivation of the enzyme in
“zero-time” at standard cycling temperatures. This combination of features makes the polymerase an ideal solution for routine and high
throughput PCR applications. Phire® Hot Start II DNA polymerase delivers superior performance in conventional thermal cyclers as well as in
fast instruments, such as the Piko® Thermal Cycler.
