DNA sequencing using Taq polymerase.
Three DNA polymerases, namely E.coli DNA polymerase 1 (Klenow), reverse transcriptase and T7 DNA polymerase (sequenase), are commonly used for DNA sequencing by the chain termination method of Sanger and colleagues [1). However, the secondary structure of the DNA template can impede the progress of all three polymerases. I have developed a novel procedure in which the thermostable polymerase of...
متن کاملA simplified protocol for producing Taq DNA polymerase in biology laboratory
Background: Taq DNA polymerase is a very important enzyme for molecular biological studies such as DNA amplification and DNA sequencing by the PCR. It is a standard enzyme that is used in 90% of molecular biology labs today. The aim of this study was to produce Taq DNA polymerase enzyme in E. coli by a reliable, practical, simple and low cost method. Materials and Methods: In this study, the T...
متن کاملData of expression and purification of recombinant Taq DNA polymerase
Polymerase chain reaction (PCR) technique is widely used in many experimental conditions, and Taq DNA polymerase is critical in PCR process. In this article, the Taq DNA polymerase expression plasmid is reconstructed and the protein product is obtained by rapid purification, ("Rapid purification of high-activity Taq DNA polymerase" (Pluthero, 1993 [1]), "Single-step purification of a thermostab...
متن کاملTaq DNA Polymerase Mutants and 2'-Modified Sugar Recognition.
Chemical modifications to DNA, such as 2' modifications, are expected to increase the biotechnological utility of DNA; however, these modified forms of DNA are limited by their inability to be effectively synthesized by DNA polymerase enzymes. Previous efforts have identified mutant Thermus aquaticus DNA polymerase I (Taq) enzymes capable of recognizing 2'-modified DNA nucleotides. While these ...
متن کاملHeat-mediated activation of affinity-immobilized Taq DNA polymerase.
A novel strategy for heat-mediated activation of recombinant Taq DNA polymerase is described. A serum albumin binding protein tag is used to affinity-immobilize an E. coli-expressed Taq DNA polymerase fusion protein onto a solid support coated with human serum albumin (HSA). Analysis of heat-mediated elution showed that elevated temperatures (> 70 degrees C) were required to significantly relea...
