NH-bis(PEG2-propargyl) is a multi-branched linker with two terminal propargyl groups and an amino group. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry to yield a stable triazole linkage. The amino group is reactive with carboxylic acids, activated NHS esters, and carbonyls. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Overview
Detection kits for WNV
CE-IVD marked version available for in vitro diagnostic use
Available in TaqMan format for analysis
West Nile Virus (WNV) belongs to the RNA virus family of Flaviviridae. It is known to spread primarily through arthropod vectors such as mosquitoes. The virus infects mainly birds but is also reported to infect humans as well as pets such as cats and dogs. In humans, the majority of the infections caused by WNV are asymptomatic. However, some individuals (the majority of the confirmed cases) could enter a second, febrile stage with flu-like symptoms – commonly known as West Nile Fever. In a more serious stage, the disease becomes neuroinvasive, causing meningitis or encephalitis. Such severe conditions could lead to mortality. As the symptoms of WNV are very similar to other common diseases but can be fatal at a severe stage, it is important to distinguish the virus early in the diagnosis, particularly at the molecular level.
WNV TaqMan RT-PCR Kit, 100 reactions
Ready to use format, including Master Mix for the target and PCR control to monitor for PCR inhibition and validate the quality
Specific Primer and Probe mix for the pathogen/virus/viroid of interest
Primer and Probe mix
Positive and negative control to confirm the integrity of the kit reagents
WNV TaqMan RT-PCR Probe/Primer Set and Controls, 100 reactions
Specific Primer/Probe mix and Positive Control for the pathogen/virus/viroid of interest
Nuclease-free water
Can be used together with Norgen’s RT-PCR Master Mix (#28113) or customer supplied master mix
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. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
Sputum Liquification Buffer (Cat. 28289) can be purchased separately
This kit constitutes an all-in-one system for the rapid isolation of DNA from sputum samples. It allows for the isolation of bacterial or eukaryotic DNA from the sputum samples using spin-column chromatography based on Norgen’s proprietary resin. The kit includes all the reagents needed to process sputum DNA. The protocol can be completed in 30 minutes. Purified DNA is of the highest quality and free from inhibitors, and can be used in sensitive downstream applications including PCR and qPCR.
Background
A sputum specimen is the name given to the mucus which is expectorated from the lower airways. High quality sputum samples should contain very little saliva, as this may contaminate the sputum sample with oral bacteria. Sputum samples are typically evaluated to look for infections such as Moraxella catarrhalis, Mycobacterium tuberculosis, Streptococcus pneumoniae ;and Haemophilus influenza. Other pathogens can be detected in sputum as well, including HIV. In addition, sputum samples are useful in the detection of lung cancer or to evaluate chronic inflammation.
* Average DNA yield will vary depending on the health status of the donor
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment.
Norgen’s Sputum DNA Isolation Kit contains ready-to-use Proteinase K, which is dissolved in a specially prepared storage buffer. The buffered Proteinase K is stable for up to 2 years after the date of shipment when stored at room temperature.
Annexin A1 (ANXA1) is a membrane protein that plays a role in innate and adaptive immunity by controlling the biosynthesis of inflammation, prostaglandins, and leukotriene mediators. This target is overexpressed in 97% of all samples from patients with with hairy cell leukemia, and is absent in other B-cell lymphomas. High ANXA1 expression is frequently associated with advanced stage esophageal and esophagogastric junction adenocarcinoma, and is also linked to advanced and metastatic disease states.
