High fidelity polymerase definition
WebNEB scientists were the first to identify and commercialize a high-fidelity DNA polymerase suitable for PCR, namely Vent ® DNA Polymerase. Since its discovery, several other high fidelity polymerases have been discovered and engineered – all with differing processivity, speed and levels of accuracy. WebEach lot of Pwo DNA polymerase is assayed for: Activity: The enzyme is tested on activated DNA.; Function: The enzyme is tested in two PCRs, using λDNA and human genomic DNA as templates.; Proofreading ability: Proofreading activity is assayed according to the laq Iq fidelity assay [Frey, B. & Suppmann, B. (1995) Biochemica 2. 8-9].; …

This high fidelity derives in part from an integral 3'→5' proofreading exonuclease activity in Vent DNA Polymerase (1,3). Greater than 90% of the polymerase activity remains following a 1 hour incubation at 95°C. Amplification of Jurkat ...
WebThe fidelity of a DNA polymerase is the result of accurate replication of a desired template. Specifically, this involves multiple steps, including the ability to read a template strand, select the appropriate nucleoside triphosphate and insert the correct nucleotide at the 3´ primer … WebThe level of fidelity can also be expressed in relative terms, often using Taq DNA polymerase as the relative standard (Table 1). Note that while single base substitution errors are the easiest to assess, polymerases are also capable of insertion/ deletion errors that can lead to frameshift mutations, a highly deleterious type of error.
