Product information "SNP Pol DNA Polymerase"

SNP Pol DNA polymerase 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.

SNP PolTaq DNA polymerase shows also 5'-3'-nuclease activity and is therefore suitable for hydrolysis probe-based assays (Taqman®, molecular beacons, etc.).

Test sample available at a special price! No shipment costs within Germany. The test sample price will be refunded on the first official order of the product.

Description
SNP Pol DNA Polymerase (High Discrimination of single nucleotides) is a highly selective DNA polymerase. It has been specially developed for allele-specific discrimination where a high discrimination rate is needed: 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.

Application Note for HiDi DNA Polymerase

 

We recommend designing primers with a 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.

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.

With our high quality dNTPs as Set (M3015.4100) or Mix (M3016.1010) or our DNA Ladders and our favourable standard agarose (M3044) we can offer additional products for your PCR.

- DamID-seq data in C. elegans.

As an alternative to ChIP, DNA adenine methyltransferase identification by sequencing (DamID-seq) was recently shown to be able to characterize binding sites in single mammalian cells. Additionally, DamID can be achieved for cell-type specific analysis by expressing Dam fusion proteins under tissue specific promoters in a controlled manner. In this report, we present a user-friendly pipeline to analyse DamID-seq data in C. elegans.
