Pure-NA rTaq DNA Polymerase (Recombinant), 500U


Pure-NA™ rTaq DNA Polymerase is a 94 kD thermostable DNA polymerase. It is an enhanced Taq DNA polymerase which is suitable for all standard PCR applications. Pure-NA™ rTaq DNA Polymerase is treated with specific mutation based on the kinetic principle of enzyme reaction. It has low dependence on enzyme activator and low mismatching rate in amplification hence it has high efficiency of amplification. The amplified products have long fragment with good specificity. The amplified DNA fragment has an A base at 3' end, which makes it easy to be used in downstream application such as TA clone directly.
