    Norgen’s Stool Nucleic Acid Collection and Preservation System is a complete system designed for collection, ambient storage and transport of nucleic acids from stool specimens. Each of the 50 clamshells contain: nitrile gloves, alcohol swabs, Fe-Col® Collection Paper, and Norgen’s Stool Nucleic Acid Collection and Preservation Tube containing Norgen’s Stool Preservative in a liquid format. The user simply collects the stool specimen using the provided Fe-Col® Collection Paper, and then transfers the stool into the Stool Nucleic Acid Collection and Preservation Tube using the spoon attached to the lid. The sample is then mixed gently until the stool is well submerged under the preservative. 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 up to 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. The Stool Preservative also prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely.
