N-(Boc-PEG4)-N-bis(PEG4-propargyl) is a trifunctional chemical containing two terminal alkynes and a Boc-protected primary amine. The terminal alkynes are used in copper click chemistry with azides to form stable triazole linkages with the target molecule while the carboxylic acids are reactive towards alcohols and primary amines to form esters and amides respectively.

iDi® stands for High Discrimination of mismatches at the 3’-terminus of primers in PCR. This myPOLS Biotec enzyme family is optimized for this feature and is the first choice for applications that rely on this property such as allele-specific PCR (asPCR) or allele-specific amplification (ASA).HiDi® Taq 2x PCR Master Mix – ready to use mix simplifies your PCR setup. Only target-specific primers and template need to be added as the mix contains all components for a successful and reliable PCR. This ensures reproducible results, significantly reduces set-up times and the risk of pipetting errors.Please note: This PCR mix is also available as a mix with a nuclease deficient variant, featuring higher robustness towards potential PCR inhibitors and compatibility with real-time dyes such as our GreenDye.Benchmarking with products of competitors conducted by us and others show that the HiDi® DNA polymerase family is the first choice for highly selective PCRs, such as genotyping by allele-specific PCR, HLA genotyping, analysis of single CpG methylation sites or the detection of mutations in a high background of wild-type sequences. By using HiDi® Taq DNA polymerase, less than 10 copies of a mutation can be detected in a background of >10.000 wild-type copies straight away without any other tedious assay optimization.HiDi® Taq DNA polymerase harbours a nuclease function and therefor is also suitable for use with hydrolysis probes (TaqMan® probes etc.). It has also been shown that HiDi® DNA polymerase family is highly suitable for quality control and mutation identification in CRISPR-Cas or TALEN-based applications.Several independently conducted studies show that HiDi® Taq DNA polymerase is ideally suited for use in asPCR in numerous research areas ranging from mutation detection to genome editing.

Example Primer Design
Matching vs. mismatching nucleotide is placed at the 3′-end of the primer for best discrimination results.
Example Results – There´s no accounting for taste
Cilantro: some people love it in their food, some hate it. Here we are detecting a genomic SNP (rs72921001) in HeLa genomic DNA. This SNP is reported to be close to a number of genes coding for olfactory receptors. (Reference: Eriksson N. et al. (2012), “A genetic variant near olfactory receptor genes influences cilantro preference.”)
Considering, that only the C-allele specific primer is extended and yielding in a specific amplicon, we can conclude a genetic predisposition in disliking cilantro, as this SNP is significantly associated with detecting a soapy taste to cilantro.
Allele-specific PCRs were performed from 1 ng/µl of HeLa gDNA in the presence of a realtime dye, indicating the amplification of the C-allele specific primer only. The A-allele specific primer is discriminated, thus not amplified up to 50 cycles.
PCR products were subsequently analysed on a 2.5% agarose gel. Specific product is visualized by ethidium bromide staining at the amplicon length of 109 bp.

Volcano3G® RT-PCR Probe 2x Master Mix contains all components required for general RT-qPCR – optimized reaction mixfor sensitive and reliable results – engineered, truly thermostable Taq DNA polymerases with reverse transcriptase activity – fast start function due to a hotstart aptamer formulation which prevents unspecific amplification at lower temperatures (<57°C) – Pipetting aid in form of a blue dye for better visibility during aliquoting into well-plates – included lysis function*
* = A sample extraction and sample lysis is not necessary as immediate hot PCR cycling conditions can brake cell- and virus membranes. Please see our published references to this product.
Note: Volcano3G® RT-PCR Probe 2x Master Mix is a unique master mix. If you are using it for the first time, we recommend to design primers to have higher melting/annealing temperatures (above 65°C). Additionally, for assay setup it is advised to perform RT-PCR test reactions with temperature gradients (i.e., for the annealing and extension steps) to identify the most proficient PCR protocol for your needs using our Volcano DNA polymerase products.
