Proofreading Polymerasen

AQ97 Hot Start 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.

ReproHot Proofreading DNA Polymerase – the Hot Start All-Round Solution for Standard PCRs ReproHot Proofreading DNA Polymerase is the hot start all-round polymerase for reliable, precise, and reproducible PCR results in everyday laboratory workflows. As the hot start variant of the proven ReproFast technology, it combines our classic Taq DNA polymerase and a proofreading polymerase with a monoclonal antibody that specifically inhibits polymerase activity prior to the first denaturation step. This antibody-based hot start technology makes ReproHot an ideal all-round solution for all standard PCR applications. It effectively prevents non-specific amplification, primer-dimer formation, and background artifacts caused by unwanted primer binding at room temperature. The antibody is fully inactivated at temperatures above 75 °C, so no extended initial denaturation step is required. ReproHot reliably amplifies targets up to 5 kb from human genomic DNA and up to 7 kb from lambda DNA with consistent yield and improved specificity – perfect for laboratories seeking a powerful hot start all-round polymerase with minimal optimization effort. The Hot Start All-Round Polymerase – Key Advantages Hot start all-round technology: Antibody-mediated inhibition prevents primer-dimers and non-specific products Perfect balance: Taq for speed and yield, proofreading for increased accuracy Universally applicable: Optimized buffer for a broad range of standard PCR applications Proven performance: Up to 5 kb (human gDNA) / 7 kb (lambda DNA) Workflow boost: Room-temperature setup, less optimization, more reproducible results Cost-efficient all-round alternative: High performance alternative to Phusion DNA Polymerase Practical Benefits for the Laboratory Reliable PCR setups for cloning, genotyping, and screening High reproducibility for service laboratories and high-throughput workflows A single all-round polymerase reduces enzyme variety, storage requirements, and workflow complexity Well suited for complex templates and low target concentrations With ReproHot Proofreading DNA Polymerase, you choose a hot start all-round enzyme that combines specificity, robustness, and efficiency – for dependable PCR results without additional optimization.

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.
