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.

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.

Genaxxon’s FAST DNA polymerase (2X) MasterMix with dye is the master mix of our FAST DNA polymerase (M3285) which is a robust enzyme, ideally suited for applications like genotyping and screening, amplifying with extreme speed of up to 2 seconds per 1kb, as well as high yield and consistency. FAST DNA polymerase has 5’-3’ exonuclease activity, but no 3’-5’ exonuclease (proofreading) activity. PCR products generated with this enzyme are A-tailed and can thus be cloned into TA cloning vectors. The extreme speed of Genaxxon’s FAST DNA polymerase allows the use of an extension rate of 4-8 kb/min. Genaxxon bioscience’s FAST DNA Polymerase (2X) MasterMix with dye includes all components needed for a fast PCR, except the primers. Besides this, it includes an inert red tracking dye for gel electrophoresis. Therefore, upon completion of the PCR, the reaction is ready for direct loading onto an agarose gel without the need of adding an additional loading buffer.Example of a typical PCR protocol (graphical presentation)* Ta is the annealing temperature (Ta should be 2°C above Tm**)  ** Tm is the melting temperature of a primer which is defined as the temperature at which 50% of the primer bind to the complementary sequence of the target DNA. Please note: By increasing Ta above Tm, this percentage decreases, however, primers will still anneal up to a certain degree and initiate extension. Therefore, PCR would still work with a Ta of several degrees higher than the Tm but with a dramatically reduced efficiency. Hence, we recommend optimizing the Ta by performing a temperature gradient (e.g., starting at the lowest Tm or a few degrees below and increasing with 2°C increments). *** Largest tested amplicon size: 5kb. Please note that longer extension times may be required for targets larger than 5kb!

The SNP Pol DNA polymerase > used for the SNP Pol 2X Mastermix has been specially designed for easy, reliable and rapid allele-specific discrimination, eg. CRISPR / Cas9 point mutations, for detecting incorrect CRISPR / Cas9 products, or validating sequencing results. The SNP Pol DNA polymerase distinguishes highly specific, whether a mismatch of the primer-template-complex is present or not. The mismatch (point mutation) must be at the 3 'end of the primer. Thus, mutant alleles can be distinguished exactly from wild-type alleles - without sequencing, since the polymerase simply does not amplify in the case of a mismatch. Just place your primer on the supposed point mutation (Important: The point mutation must be at the 3 'end) and the polymerase will detect a mismatch in this region with almost 100% accuracy: If the template base complementary to the 3' end of the primer shows the mutation and the primer does not, no amplification takes place - 100% certainty within a short time!The SNP Pol DNA polymerase can therefore be easily, time and cost-effectively used for the screening of point mutations. The variant SNP PolTaq DNA polymerase has 5'-3 'nuclease activity and can therefore be used for specific hydrolysi probes such as Taqman® probes or Molecular beacons. For more information on our SNP DNA polymerases and applications, read our blog now. DescriptionSNP Pol DNA Polymerase and SNP PolTaq Polymerase are  highly selective DNA polymerase for the detection of Single Nucleotide Polymorphisms. It was developed specifically for allele-specific discrimination, where a very high discrimination rate is required e.g., in allele-specific PCR (ASA; AS-PCR), allele-specific primer extension (AS-PEX), SNP analysis, genotyping or in methylation-specific PCRs (MSP). Many other DNA polymerases tolerate mismatched primer-template complexes and are therefor not suitable. The SNP Pol DNA polymerase, on the other hand, distinguishes these specifically (high discrimination) and supplies only PCR products with perfectly matching primer pairs! The Genaxxon SNP Pol and SNP PolTaq DNA polymerases differ up to 100% by means of allele-specific PCR between the two alleles and, after a simple qPCR, give a clear result as to which allele is present. Thus, the principly great potential of the CRISPR/Cas9 technology can be used for human medicine and plant biotechnology especially together with the SNP PolTaq or SNP Pol DNA polymerase. Allele-specific PCR can be used to quantify the mutation rate in a pool or background of wild-type sequences. The verification of mutation frequencies determined by NGS can also be verified by means of allele-specific PCR and SNP Pol DNA polymerase. The SNP PolTaq DNA polymerase is very suitable for the analysis of liquid biopsy samples. With SNP PolTaq, the presence and frequency of cancer mutations can be analyzed and quantified very well. Picture below: Application note SNP Pol DNA Polymerase   We recommend short amplicon length (about 60-200 bp) for best results, but also longer amplicon lengths are possible. The addition of additional Magnesium (+0.5 - 1.5mM) might be needed in case of longer amplicons >500 bp.Trouble shooting: No bands after PCR of 30 cycles! Optimisation procedure for missing or weak bands.Annealing temperature is too low! Attention: The SNP Pol is an aptamer inhibited DNA polymerase. The aptamer oligo used reversibly inhibits the polymerase at temperatures <55°C! Therefore, the primers should ideally have an annealing temperature of >57°C. - realtime PCR approach - Check the dNTP concentration. This should be between 200 and 300µM (in the PCR). - Increase the number of cycles (at least 35, preferably equal to 40) Test optimisation - number of cyclesIn endpoint detection, a cycle count of 30 is not always sufficient to generate a clearly visible band. For example, with less than 200 DNA copies as a starting value. The test should therefore be run using real-time PCR, or five parallel PCRs should be used, one of which is taken from the PCR device after each of five different cycles (example below). Endpoint detection: Set up five identical PCR reactions in parallel using the SNP Pol DNA polymerase. Remove one of the PCR tubes from the cycler at each of 20, 25, 30, 35 and 40 cycles and apply all five reactions to an agarose gel at the end. This makes it easy to recognise which is the optimum number of cycles in the PCR for the given application (starting material, target, primer). SNP Pol PCR with cell lysates Animal cells and E.coli can be used directly for PCR with the SNP Pol DNA polymerase! No separate lysis or proteinase K digestion is necessary. PCR procedure:1. 50 - 500 cells are required per PCR batch! 2. prepare PCR mix with primers and buffer and place on ice! 3. add the picked colony directly to 10-20µL water (no separate lysis and no proteinase K digestion), vortex briefly (5 seconds), then add this cell suspension directly to the PCR reaction mixture, e.g. 10µL cell suspension for a PCR preparation with a total volume of 20µL. An initial denaturation time of 2-3 minutes is sufficient is sufficient, can be extended to 5 minutes if necessary. Genomic DNA per reaction max. 100 copies is relatively low, but should still work. The remainder of this cell suspension can also be frozen away in order to carry out further tests. Optional: 4. if possible: do real-time PCR!The SNP Pol DNA polymerase (M3009 > or M3061 >) can be used together with non-specific fluorescent dyes (eg Genaxxon's Green DNA Dye > or SybrGreen®) in real-time PCR. When working with specific PCR probes, only the SNP PolTaq DNA polymerase can be used, since only these have a 5'-3 'exonuclease activity.
