Stool Nucleic Acid Collection and Preservation Tubes

Norgen’s Stool Nucleic Acid Collection and Preservation Tubes are designed for the rapid preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Tubes contain Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated in the label) and mixes gently until the stool is well submerged under the 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 at the arrival to testing facilities until the RNA purification.
