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 کاملNaOH treatment to neutralize inhibitors of Taq polymerase.
The introduction of polymerase chain reaction (PCR) into the forensic field has greatly extended the ability to analyze DNA from small or degraded samples. However, one significant problem with PCR analysis is the sensitivity of Taq Polymerase to inhibitors found in many substrates commonly encountered with evidentiary materials. We hypothesize that the most problematic of these compounds inter...
متن کاملSwedish Patent Litigation in Comparison to European
Swedish patent litigation in comparison to European. Access to the published version may require subscription. Introduction A first large-scale systematic comparison of patent litigation across European jurisdictions was published in 2013 by Cremers et al., with data from Germany, UK (England and Wales), France and the Netherlands. 1 We have developed comparable statistics for Swedish patent ca...
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 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...
