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.

Norgen’s EXTRAClean Plasma/Serum Exosome and Free-Circulating RNA Isolation Kit constitutes an all-in-one system for the purification of exosomes and the sequential isolation of RNA and free-circulating RNA from different plasma/serum sample volumes ranging from 50 μL and up to 10 mL. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or any protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. The purified RNA can be used in a number of downstream applications including real time PCR, NGS application, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
