Propargyl-PEG4-methylamine is a PEG linker that can be react with azide compounds in copper catalyzed azide-alkyne Click Chemistry reactions. The methylamine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The PEG spacer increases hydrophilicity of the linker in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Campylobacter jejuni is a curved, rod-shaped and microaerophillic gram negative bacterium. It is one of the most common causal agents of gastroenteritis with diarrhea as the main symptom. While infection of C. jejuni is seldom life-threatening, it is considered one of the most common food-borne bacteria with over 2 million people infected per year in US alone. Infection of C. jejuni usually results from consumption of poorly prepared food including undercooked meat (particularly poultry), untreated water or raw unpasteurized milk. Traditional identification of C. jejuni involves culturing, however the microaerophilic characteristic of this bacterium make the enrichment process laborious and costly.

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. 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.

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.

The Norgen water purification system has been designed in conjunction with experts from Millipore Sigma. The Ultrapure NFW is purified in a two-stage process. The first stage, to produce type II water, includes pre-treatment with activated charcoal and polyphosphate, this water then undergoes reverse osmosis, electro-deionization and ion exchange to remove contaminants as well as UV treatment for disinfection. The Pure water then flows to a second system in a clean room with an additional 4 layers of purification. After passing through an additional ion exchange column, the water is then subjected to Ultrafiltration to remove particulates, bacteria, & ionic contaminants down to trace level, the water is then treated with UV light (182 nm wavelength) to break down organic matter. Lastly a second Ultrafilter for the production of pyrogen-, nuclease- and bacteria-free water at 18.2 MΩ. This water is of utmost purity and suitable for direct use in molecular biology applications such as qPCR and NGS, as well as cell culture and other applications.
