WebTaqDNA polymerase, isolated from the eubacterium Thermus aquaticus, is the most commonly used enzyme for standard end-point PCR. The robustness of this enzyme allows its use in many different PCR assays. However, as this enzyme is active at room temperature, it is necessary to perform reaction setup on ice to avoid nonspecific … WebThe story of modern PCR begins in 1976 with the isolation of Taq DNA polymerase from the thermophilic bacterium Thermus aquaticus. Its isolation meant that molecular biologists now had a thermostable enzyme that was capable of repeat PCR cycling without the need to add fresh DNA polymerase after each cycle.
