Optimum temperature for taq polymerase
Did you know?
WebExtensions are normally performed at 68°C. As a general rule, use extension times of one minute per 1000 base pairs (e.g. 3 minutes for a 3 kb product) For products less than 1 kb, …
WebDNA polymerase was first isolated from T. aquaticus in 1976. [10] The first advantage found for this thermostable (temperature optimum 72°C, does not denature even in 95 °C) DNA polymerase was that it could be isolated … WebOct 12, 2024 · Optimum temperatures for a range of enzymes commonly used in the lab are shown in Table 2. As you can see, there’s quite a big range, from between 75-80ºC for Taq polymerase down to 25ºC for DNA …
WebWhereas Ab-Taq and Chem-Taq are only activated once the reaction temperature is raised to 94–95°C, the aptamer in NEB-HS Taq dissociates from the polymerase at much lower temperatures (Tm = approximately 45°C), eliminating the need for a specific high temperature activation step, and enabling faster protocols (Table 1). Furthermore ... Taq's optimum temperature for activity is 75–80 °C, with a half-life of greater than 2 hours at 92.5 °C, 40 minutes at 95 °C and 9 minutes at 97.5 °C, and can replicate a 1000 base pair strand of DNA in less than 10 seconds at 72 °C. At 75–80 °C, Taq reaches its optimal polymerization rate of about 150 nucleotides per second per enzyme molecule, and any deviations from the optimal temperature range inhibit the extension rate of the enzyme. A single Taq synthesizes about 60 n…
