A simple and efficient method for extraction of Taq DNA polymerase ...
Introduction. PCR is a most widely-used technique in biology, which utilizes thermostable DNA polymerase from Thermus aquaticus (Taq) [1], [2]. The gene that encoded the Taq DNA polymerase had been cloned and expressed in Escherichia coli efficiently [3]. This has greatly facilitated the production and reduced the price of the enzyme.
