For the detection of the SARS-CoV-2 (20I/501Y.V1 UK)
Rapid detection of specific detection profiles
High priming efficiency
Sensitive to < 100 copies of target
Positive copy number standard curve for quantification
Accurate controls to confirm findings
96 reactions, includes master mix
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.

Overview
Isolate genomic DNA from all types of bacteria (both Gram-positive and Gram-negative)
Rapid and convenient spin column protocol
96-well format available for high throughput
High yield, high quality DNA for sensitive downstream applications including sequencing, PCR, qPCR and more
This kit is designed for the rapid spin column preparation of genomic DNA from 2 x 109 viable bacterial cells (between 0.5 and 1.0 mL of culture). This kit can be used for both Gram-negative and Gram-positive bacteria including Escherichia coli and Bacillus cereus. Purified genomic DNA is of an excellent quality and yield, and is fully compatible with restriction enzyme digestions, sequencing, PCR, qPCR and more. Also available in 96-well format for high throughput applications.
* Yield will vary depending on the type of sample processed
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 1 year after the date of shipment. The kit contains a ready-to-use Proteinase K, which is dissolved in a specially prepared storage buffer. The buffered Proteinase K is stable for up to 1 year after the date of shipment when stored at room temperature.
Double-Strand Specific dsDNase (dsDNase) is ideal for fast and effective removal of contaminating DNA from PCR master mixes.
Taq polymerases are commonly contaminated by bacterial DNA. This is a problem in PCR based bacterial typing and detection as it might cause false positive results. The unique properties of dsDNase make it suited for removal of contaminating DNA from PCR master mixes prior to addition of DNA template.
In figure 1, a PCR master mix was treated with different amounts of dsDNase before performing a qPCR to measure the contaminating bacterial DNA in the master mix. ArcticZymes dsDNase effectively removed contaminating DNA below known levels of the assay detection limits.
The dsDNase from Arctic shrimp (Pandalus borealis) is recombinantly produced in Pichia pastoris. It cleaves phosphodiester linkages in DNA to yield oligonucleotides with 5’-phosphate and 3’-hydroxyl termini.
The specific activity is estimated to be 30 times higher than that of bovine DNase I. In the presence of magnesium as only divalent cation and using oligos as a substrate, the activity towards dsDNA is 5000-fold higher than towards ssDNA.
The unique double strand-specificity allows specific degradation of dsDNA while leaving shorter ssDNA as primers and probes essentially intact. Easy inactivation by moderate heat (65°C) allows addition of DNA intended for analysis directly after removal of contaminating DNA.
Can be heat-inactivated by moderate heat treatment (65°C for 15 minutes)

A PCR master mix was preincubated with various concentrations of dsDNase. After treatment, no DNA was amplified in non-template controls.
Properties
Specificity towards double-stranded DNA
Nucleic acid specificity has been tested towards double- and single-stranded DNA and RNA oligonucleotides. The specificity of dsDNase towards the substrate has been measured using 15-mer oligonucleotides with FAM at 5′ and DarkQuencher® 3′ (Eurogentec). The fluorescence is proportional to enzyme activity. Assay conditions: 25 mM Tris pH 7.5, 5 mM MgCl2, and 2 μM oligonucleotide.

Giardiasis is a disease of the small bowel caused by the protozoan parasite Giardia intestinalis (syn.duodenalis or lamblia). Giardia is one of the most common intestinal parasites in the world, and occurs at very high prevalence rates in places with poor water sanitation. Individuals become infected through ingesting or coming into contact with contaminated water, food or soil. It can also be spread through the faecal-oral route due to poor hygiene practices, which makes it common in day-care centers. G. intestinalis lives inside the intestines of infected humans or other animals including cats, dogs, birds, cows, beaver and deer. Symptoms of infection include diarrhea, malaise, excessive gas, bloating, nausea, diminished interest in food, possible vomiting and weight loss.
There are 2 kits available for the detection of Giardia intestinalis:
Storage Conditions and Product Stability All kit components can be stored for 1 year after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival.
