Taq polymerase thermostable
WebJan 1, 2013 · Taq DNA polymerase: Low levels of Taq polymerase can cause incomplete primer elongation or untimely termination of the PCR product synthesis during the extension step. Too much polymerase will result in an excessive background of unwanted DNA fragments, which will look like a smear on the gel. WebDescription. Taq DNA Polymerase (a) is a thermostable enzyme of approximately 95 kDa isolated from Thermus aquaticus. This unmodified enzyme replicates DNA at 74°C and exhibits a half-life of 40 minutes at 95°C. The enzyme catalyzes the polymerization of nucleotides into duplex DNA in the 5´~3´ direction in the presence of magnesium and ...

WebTaq-polymerase is normally used to catalyze reaction at 72 °C, whereas thermostable proofreading polymerases have lower optimal temperature and are normally used to catalyze reactions at 68 °C. The success of PCR can depend on the primers’ concentration and the choice of a particular thermostable polymerase. WebPfu DNA Polymerase, derived from the hyperthermophilic archae Pyrococcus furiosus, has been shown to exhibit superior thermostability and proofreading properties compared to other thermostable polymerase. Unlike Taq DNA Polymerase, highly thermostable Pfu DNA Polymerase possesses 3′ to 5′ exonuclease proofreading activity that enables the ...
Taq polymerase is a thermostable DNA polymerase I named after the thermophilic eubacterial microorganism Thermus aquaticus, from which it was originally isolated by Chien et al. in 1976.
