NovaTaq™ Hot Start DNA Polymerase is a chemically modified form of Taq DNA polymerase that is inactive at ambient temperature. The enzyme provides improved specificity when compared to standard Taq DNA polymerase and can minimize the generation of nonspecific amplification products, such as primer-dimers and misprimed products. The enzyme must be activated by heat treatment (7–10 min at 95°C), after which thermal cycling can proceed. The enzyme generates PCR products with 3'-dA overhangs, suitable for cloning with the Novagen Perfectly Blunt®, AccepTor™, and LIC Vector Kits.
Features and Benefits:
- Higher PCR specificity and yield
- Improved low-copy target amplification
- Ambient temperature setup compatible with automation
- Target amplification of up to 5 kbp
- Ideal for quantitative and high-throughput PCR applications
One unit is defined as the amount of enzyme that will catalyze the incorporation of 10 nmol of dNTP into acid-insoluble form in 30 min at 72°C, in a reaction containing 25 mM TAPS (tris-[hydroxymethyl]-methyl-amino-propane-sulfonic acid, sodium salt), pH 9.3 at 25°C, 50 mM KCl, 2 mM MgCl2, 1 mM 2-mercaptoethanol, 0.2 mM dATP, dGTP, and dTTP, 0.1 µM [a-32P]dCTP, and 12.5 µg activated salmon sperm DNA in a volume of 50 µl.
