Propargyl-PEG3-acid is a reagent with an alkyne group and a carboxylic acid. The terminal carboxylic acid can form amide bond with primary amines (activation is needed). The alkyne can form triazole linkage with azide containing molecules via copper catalyzed reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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 bacteria, and Staphylococcus aureus is often considered the most common cause of contagious mastitis in dairy herds. S. aureus infection is estimated to be present in up to 90% of dairy farms and is responsible for 35% of the economic loss in the dairy industry (Lee et al., 2005). S. aureus is a facultatively anaerobic, Gram positive bacterium. The majority of S. aureus strains are catalase-positive and coagulasepositive, which forms the basis of traditional identification methodology.
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.
Ensure the stability and viability of viruses, chlamydia, and mycoplasma.
Manufactured based on CDC formula.
Antimicrobic blend suppresses bacterial and fungal contamination.
Supplied in bulk (1 Litre) to provide options for custom applications.
Preserve swab samples for up to 48h when preserved at 2–8°C.
Norgen’s Viral Transport Medium is formulated to transport samples that are presumably infected with a virus. Viral Transport Medium is manufactured based on CDC formula and is offered in bulk to provide an option to readily assemble swab collection devices for sample collection.
Norgen’s Viral Transport Medium (VTM) is designed for safe and efficient transport of viral samples, including but not limited to those from nasal, throat, and other swabs. The VTM contains a balanced mix of Hank’s Balanced Salt Solution (HBSS), heat-inactivated fetal bovine serum (FBS), gentamicin sulfate, and amphotericin B to preserve the viability of viruses and prevent the growth of contaminating bacteria and fungi. The medium ensures the stability and viability of viruses, chlamydia, and mycoplasma for analysis using different techniques. In addition, the Viral Transport Medium eliminates the need to immediately process or freeze samples.

Storage Conditions and Product Stability The Viral Transport Medium can be stored at 2-8°C for up to 1 year from the date of manufacturing without any reduction in performance.
DBCO-NHCO-PEG4-amine is a carboxyl-reactive building block with extended PEG spacer arm. The hydrophilic PEG spacer arm improves water solubility. In the presence of of activators (e.g. EDC, or HATU), this reagent can be used to derivatize carboxyl groups or activated esters (e.g. The NHS ester) through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
