Propargyl-PEG4-(CH2)3-CO2H is a linker containing a propargyl group at one end and a carboxylic acid at the other end. The carboxylic acid reacts with amine groups in the presence of activators (EDC or HATU). Under the catalyzation of copper, the propargyl group forms linkage with azide group of biomolecules. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview
The process of automatically removing seals from plates has become more popular due to the repetitive task of removing plate seals, which can potentially lead to cross contamination, repetitive motion injuries & plate/seal damage.
Application: Automatic & Manual MicroPlate Seal Removal
Suitable for use in the Automated Plate Seal Remover (formally XPeel)

HiDi® 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).Please note: This DNA polymerase is also available as 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.
