Compatible with most DNA and RNA isolation methods
Norgen’s Total Nucleic Acid Preservation Tubes Dx are designed for ambient preservation and transport of total nucleic acids (DNA and RNA) from samples collected using a swab. The Total Nucleic Acid Preservation Tubes contain Norgen’s Total Nucleic Acid Preservative in a liquid format. The user simply collects the specimen using a sterile nylon flocked swab (not provided), and then transfers the swab into the Total Nucleic Acid Preservative. The 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 Total Nucleic Acid 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 preservative allow DNA samples to be stored at room temperature for over 4 months and RNA samples to be stored at room temperature for over 2 months. This kit is ideal for collecting and preserving nasal and oral swab samples for in vitro diagnostic use for medical purposes. This kit can be used to preserve viral RNA, including SARs-CoV-2 RNA for detection of COVID-19.
Norgen’s Total Nucleic Acid Preservation Tubes Dx are intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.
Norgen’s Total Nucleic Acid Preservation Tubes Dx do not provide a diagnostic result. It is the sole responsibility of the user to use and validate these devices in conjunction with a downstream in vitro diagnostic assay.
Shelf Life and HandlingThe tubes should be kept tightly sealed and stored at room temperature for up to 1 year without any reduction in performance (The collection due date is written on the device label and the kit box label).Once collected, RNA is stable for up to 2 months and DNA is stable for up to 4 months when the tubes are kept tightly sealed and stored at room temperature.
Propargyl-PEG8-bromide is a PEG reagent containing an alkyne group and a bromide group. The alkyne group can react with azide-bearing compounds or biomolecules in Click Chemistry reactions under the catalyzation of copper. The PEG spacer increases water-solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
