Description. Mutagenic primers and pUC/M13 DNA Polymerase Fidelity* Received for publication, September 22, 2000, and in revised form, November 6, 2000 polymerase I (Taq pol I) was created containing random substitutions within a portion of the dNTP binding site (Motif A; amino acids 605–617), and a fraction of all selected active Taq pol I (291 out of 8000) was tested for base pairing fidelity; seven unique mutants One unit of Platinum Taq DNA Polymerase High Fidelity incorporates 10 nmol of deoxyribonucleotide into acid-precipitable material in 30 min at 74°C. In general, enzymes which possess an associated 3′→5′ exonuclease-dependent proofreading activity are thought to exhibit higher replication fidelity than non-proofreading DNA polymerases ( 7). Molecular Biology. Taq polymerase shows low fidelity, while Pfu polymerase shows high fidelity. Agreement with the literature Invitrogen AccuPrime Taq DNA Polymerase, High Fidelity, provides qualified reagents for the high-fidelity PCR amplification of nucleic acid templates. PrimeSTAR GXL DNA Polymerase provides efficient PCR amplification even for the toughest To perform high-fidelity PCR with Taq polymerase, reactions should contain a low MgCl2 concentration, not in large excess over the total concentration of dNTP substrates, and be buffered to approximately pH 6 (70 degrees C) using Bis-Tris Propane or PIPES (Table 2). and Nicole M. This blend increases the length of amplification products by using the proofreading polymerase to repair For high speed and high performance PCR. 18 In addition to these Taq polymerase does not have 3′ to 5′ exonuclease activity, while Pfu polymerase has 3′ to 5′ exonuclease activity. 3-1. We also offer Pfu DNA polymerase for applications requiring higher fidelity amplification. To maximize the fidelity of DNA polymerases in the PCR, pH, concentrations of deoxynucleoside triphosphates, and magnesium ion were varied. T. These buffers have a pKa between pH 6 and pH 7 and a small temperature coefficient (delta Taq polymerase has no proof reading capability, i. Taq polymerase is a thermostable DNA polymerase I named after the thermophilic eubacterial microorganism Thermus aquaticus, from which it was originally isolated by Chinese scientist Alice Chien et al. g. Innovative QIAGEN PCR Buffer has been developed to save time and effort by reducing the need for PCR optimization.
