For isolation and cultivation of Listeria monocytogenes.
Principle:
Peptone provide carbon and nitrogen sources; yeast extract powder and starch provide carbon and nitrogen sources, vitamins and growth factors; sodium chloride maintains osmotic equilibrium; glucose carbon source; agar as medium coagulant.
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.

96 reactions, includes master mix
Methyltetrazine-PEG7-DBCO is a PEG linker with a terminal TCO reactive reagent and a DBCO group. DBCO is commonly used for copper-free Click Chemistry reactions. Methyltetrazine can be used to convert azido-containing peptides or proteins into tetrazine-modified peptides or protein without catalyst or axillary reagents. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Norgen’s Stool Nucleic Acid Collection and Preservation Tubes are designed for the rapid preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Tubes contain Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated on the tube) and mixes gently until the stool is well submerged under the preservative. The Stool Preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the Stool Preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the Stool Preservative allow samples to be stored at room temperature for over 2 years for DNA and 7 days for RNA. To extend the stool RNA stability in the preservative, storage at -20°C or -70°C is recommended at the arrival to testing facilities until the RNA purification.
