Proofreading Polymerasen

AQ97 High Fidelity DNA Polymerase ist eine proofreading Polymerase mit hoher Amplifikationsgeschwindigkeit und sehr hoher Genauigkeit (>60-fach) gegenüber Taq DNA Polymerase. AQ97 ist ideal für schwierige Targets mit sehr niedrigem oder hohem GC-Gehalt geeignet. Neben diesen Eigenschaften zeichnet sich die AQ97 auch durch Ihre Eignung, lange Targets bis zu 18 kb, zu amplifizieren aus. Dies führt zu sehr genauen und zuverlässigen PCR-Ergebnissen.  AQ97 High Fidelity DNA Polymerase besitzt sowohl eine 5'→3' DNA Polymerase-Aktivität als auch eine 3'→5' proofreading Exonuklease-Aktivität, die es dieser Polymerase ermöglicht, Basenpaar-Fehlpaarungen zu korrigieren. AQ97 High Fidelity DNA Polymerase ist ein fusionierter Proteinkomplex aus DNA-Polymerase mit einer prozessivitätssteigernden DNA-Bindungsdomäne. Neben einer sehr schnellen und robusten Amplifikation komplexer und langer Zielmoleküle zeichnet sich die AQ97 High Fidelity DNA Polymerase durch eine hohe Genauigkeit aus, was dazu führt, dass auch für lange Amplicons eine genaue Amplifikation gewährleistet ist. Dadurch eignet sich die AQ97 besonders für PCR-Experimente, die eine Amplifikation mit sehr niedrigen Fehlerraten erfordern, wie z. B. Klonen/Subklonen, NGS-Anwendungen, SNP-Analysen und Mutagenese. Eigenschaften: • High Fidelity: >60x Taq fidelity• High elongation rate: 10 sec/kb (bis 6000bp pro Minute)• Long range amplification: 18 kb for human gDNA• 5'-3' polymerase acitivity and 3'-5' exonuclease activity.• generates blund ends.Picture 1: Comparison figures of fidelity values for AQ97 DNA Polymerase, AccuPol DNA Polymerase, two well-recognized high fidelity DNA polymerases P and Q and Taq DNA Polymerase were determined through NGS-based analysis of nucleotide misincorporation during PCR. Initially, PCR amplification was performed on a ~ 200 bp synthetic DNA target, generating PCR products for each of the tested polymerases (using recommended setup conditions).  Picture 2: Distribution of substitution errors. PCR was performed using Taq DNA Polymerase, AQ97 High Fidelity DNA Polymerase, high fidelity DNA Polymerase Q and high fidelity DNA Polymerase P. The PCR was followed by NGS sequencing of the PCR products. The number of substitutions at each PCR target position was calculated and plotted in diagram A. Substitutions include misincorporated nucleotides and deletions at each position. Non-polymerase errors are subtracted from the total number of errors to revel true polymerase errors. Non-polymerase errors include mutations caused by thermocycling-induced DNA damage, pre-NGS sample preparation and sequencing errors. In these diagrams the average number of substitutions for Taq DNA Polymerase (Taq average) and for AQ97 High Fidelity DNA Polymerase (AQ97 average) is also plotted. Diagram B magnifies the area near the detection limit, displaying more information about the number of substitutions for AQ97 High Fidelity DNA Polymerase, high fidelity DNA Polymerase Q and high fidelity DNA polymerase P.
