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.
Norgen’s Fecal Swab Collection and Preservation System is designed for collection, ambient storage and transport of nucleic acids from stool specimens. The Fecal Swab Collection and Preservation System tubes contain Norgen’s Stool Preservative in a liquid format. The user simply collects the specimen using the provided swab, and then transfers the swab into the Stool 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 upon arrival at the testing facilities until RNA purification.

Propargyl-PEG7-NHS ester contains a propargyl group and an NHS ester. As an amine reactive reagent, this product can be used for derivatizing peptides, antibodies, amine coated surfaces etc. In the presence of copper catalyst, propargyl group reacts with azide to yield a stable triazole linkage. The PEG units help increase the hydrophilicity of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
