Exceptional value for money
Rapid detection of all clinically relevant subtypes
Positive copy number standard curve for quantification
Highly specific detection profile
High priming efficiency
Broad dynamic detection range (>6 logs)
Sensitive to < 100 copies of target
Accurate controls to confirm findings
The Primerdesign genesig Kit for Shigella species (Shigella_spp) genomes is designed for the in vitro quantification of Shigella_spp genomes. The kit is designed to have a broad detection profile. Specifically, the primers represent 100% homology with over 95% of the NCBI database reference sequences available at the time of design.
The dynamics of genetic variation means that new sequence information may become available after the initial design. Primerdesign periodically reviews the detection profiles of our kits and when required releases new versions.
The target sequence is within the virulence plasmid pCP301 (VirA) which is carried by nearly all clinical isolates of shigella. This target has previously been shown to be a good genetic marker for Shigella in other real time PCR based studies (Hiroshi Fukushima et.al 2003.) The primers and probe sequences in this kit have 100% homology with over 95% of reference sequences in the NCBI database based on a comprehensive bioinformatics analysis.

Isothermal nucleic acid Principle Summary
The kit is based on room and constant temperature nucleic acid rapid amplification technology, its principle is that at room and constant temperature, the recombinase and primer form a protein/single-stranded nucleotide complex Rec/ssDNA, and invade the double-stranded DNA template with the help of auxiliary proteins and single-stranded binding protein SSB; then form a D-loop region at the invasion point and start to scan the DNA duplex, after finding the target region complementary to the primer and disintegration of the complex Rec/ssDNA, the polymerase also binds to the 3′ end of the primer to start the chain extension. The kit relies on the role of NFO enzyme and adds the designed specific molecular probes according to the template, and get the result by colloidal gold technology (sandwich method).

2/ Please take out the required quantity of MIRA reaction units for the experiment, and put the rest under storage conditions when performing the experiment.
Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the utter is mainly caused by infection of various bacteria. Streptococcus uberis is a gram-positive bacterium that is known worldwide as an environmental pathogen responsible for a high proportion of cases of mastitis in lactating cows and is also the predominant organism isolated from mammary glands during the non-lactating period. Often it is resistant to treatment and causes persistent high somatic cell counts without clinical mastitis.
Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival.

The procedure for plasma isolation using this kit is compliant with ISO 20186-3:2019
Norgen’s cf-DNA/cf-RNA Preservative Tubes are closed, evacuated plastic tubes for the collection and the preservation of cf-DNA, circulating tumor DNA, cf-RNA and circulating tumor cells in human whole blood samples during storage and shipping. Using these tubes in combination with Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits or Norgen’s Plasma/Serum RNA Purification Kits enables the purification and concentration of an inhibitor-free cf-DNA/ct-DNA/cf-RNA in a very small elution volume. Plasma recovered from Norgen’s cf-DNA/cf-RNA Preservative Tubes is also compatible with any other cf-DNA and/or cf-RNA purification method. The purified cf-DNA, ct-DNA and cf-RNA are compatible with any downstream application assays, including PCR, qPCR, rt-qPCR, methylation-sensitive PCR, Southern Blot analysis, gene expression analysis, microarrays and NGS.
This product is for research use only and not for use in diagnostic procedures.
Performance
Norgen’s cf-DNA/cf-RNA Preservative Tubes abridge the collection/processing of whole blood for the subsequent purification of cf-DNA and/or cf-RNA. The cf-DNA/cf-RNA Preservative Tubes preserve and inhibit the programmed cell-death (apoptosis) of the blood, hence preventing the release of intracellular DNA/RNA into plasma. Whole blood samples can be shipped and stored at room temperature for the subsequent processing of plasma. The cf/ct DNA and cf-RNA levels are stable for up to 30 days at room temperature. The cf-DNA is also stable for up to 8 days at 37°C. When blood collected on Norgen’s cf-DNA/cf-RNA tubes is processed for plasma recovery no buffy coat will be generated and the Circulating tumor cells (CTCs) will be located at the bottom of the tube with the blood sediment. CTCs are stable for 14 days at room temperature where it can be extracted from the blood sediment or from whole preserved blood for cell sorting or for cf/DNA or cf-RNA purification.
Plasma samples produced from the whole blood sample collected into Norgen’s cf-DNA/cf-RNA Preservative Tubes and purified using Norgen’s Plasma/Serum Cell-Free Circulating DNA Purification Kits or Norgen’s Plasma/Serum RNA Purification Kits yield concentrated, high-quality and inhibitor-free cf-DNA/ct-DNA or cf-RNA for any downstream application.
