Our SNPsig® kits use our own proprietary genotyping method to enable the identification of SARS-CoV-2 variants of concern. These products can be used on any real-time PCR machine using familiar protocols, whilst resulting in exceptional genotyping data.
Positive control templates for wild-type and variants are supplied in every kit to make data interpretation simple.
Our SNPsig® technology provides an alternative to sequencing as well as S gene target failure (SGTF) that enables scientists to analyse and monitor these specific genomic mutations. Our kits can provide a pivotal role in screening for SARS-CoV-2 variants for the purpose of genomic surveillance and studies.

Recommended Use: Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage: Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
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 therefor, is the first choice for applications that rely on this property such as allele-specific PCR (asPCR) that is also termed allele-specific amplification (ASA).HiDi® 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.This PCR mix is also available with a full-length Taq DNA polymerase with a nuclease domain, featuring 100% compatibility with hydrolysis probes (TaqMan® probes etc.).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® 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.It has also been shown that HiDi® DNA polymerase family is highly suitable for quality control in CRISPR-Cas or TALEN-based applications.Several independently conducted studies show that HiDi® 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.

Sal-Like Protein 4 (SALL4), is a zinc finger transcription factor found in germ cells and human blood progenitor cells, with functional involvement in modulating Oct-4 to maintain embryonic stem cell pluripotency. SALL4 is a useful marker for acute myeloid leukemia, B-cell acute lymphocytic leukemia, intratubular germ cell neoplasia, seminomas/dysgerminomas, and yolk sac tumors (both pediatric and postpubertal). Anti-SALL4 is used to detect embryonal carcinomas, hepatocellular carcinoma (HCC), gliomas, ovarian primitive germ-cell tumors, choriocarcinomas, spermatogonia, teratoma, gastric cancer, breast cancer, and lung cancer. Expression of SALL4 is often associated with poor prognosis in HCC, and with metastasis in endometrial cancer, colorectal carcinoma, and esophageal squamous cell carcinoma.
