Total Nucleic Acid Preservation Tubes

Norgen’s Total Nucleic Acid Preservation Tubes are designed for ambient preservation and transport oftotal nucleic acids (DNA and RNA) from samples collected using a swab, including nasal, buccal, saliva,fecal, skin, surfaces, etc. The Total Nucleic Acid Preservation Tubes contain Norgen’s Total NucleicAcid Preservative in a liquid format. The user simply collects the specimen using a sterile nylon flockedswab (not provided), and then transfers the swab into the Total Nucleic Acid Preservative. Thepreservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and alsoinactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. Inaddition, the Total Nucleic Acid Preservative eliminates the need to immediately process or freezesamples 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 4months and RNA samples to be stored at room temperature for over 2 months.Swab samples collected and preserved using Norgen’s Total Nucleic Acid Preservation Tubes arecompatible with most commercially available DNA and RNA isolation methods. Samples stored in thetubes have been used successfully with most of Norgen Biotek’s DNA and RNA isolation kits andreagents, including Norgen’s Total RNA Purification Kit (Cat# 17200) and Norgen’s Saliva DNA IsolationKit (Cat# RU45400). For purification of total nucleic acids please refer to the supplementary protocolprovided with Norgen’s Total RNA Purification Kit (Cat#17200).
