Product Info
Overview
Complete, user-friendly system to collect, preserve and transport stool samples
Each clamshell contains nitrile gloves, alcohol swabs, Fe-Col® Collection Paper, and Norgen’s Stool Nucleic Acid Collection and Preservation Tube containing Norgen’s Stool Preservative
The preservative provides sample homogeneity eliminating sample variability
Preserve and transport DNA & RNA safely at ambient temperature
Nucleic acid preservation at room temperature over 2 years for DNA and 7 days for RNA
No cold shipping/storage needed – hassle-free and cost effective
Isolate nucleic acids for any application including 16s NGS
Robust preservation over a range of temperatures
Customizable with various accessories for easy and safe collection
Eliminates odor and renders samples safe and non-infectious
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.

Novel method
The β-Glucan Assay Kit (Yeast and Mushroom) is suitable for the indirect measurement of 1,3:1,6-β-glucan in yeast and mushroom preparations containing starch, glycogen, sucrose and trehalose.
We are happy to announce a new and improved procedure!
Trehalase enzyme has now been added to the β-Glucan Assay Kit (Yeast and Mushroom), further increasing the accuracy of β-glucan measurement for certain samples. The addition of trehalase removes instances of overestimation of β-glucan content in samples containing trehalose. Please refer to the assay protocol and the FAQ here for more information.
This product replaces the Enzymatic Yeast β-Glucan Assay Kit (K-EBHLG) as the method of measurement for β-glucan measurement in yeast samples. See here for more information.

ExcelRT™ Reverse Transcription Kit is a complete, efficient and convenient kit to synthesize high quality first strand cDNA. This kit contains ExcelRT™ Reverse Transcriptase, which is able to synthesize the first strand cDNA at 37~50°C. The ExcelRT™ Reverse Transcriptase is a recombinant Moloney Murine Leukemia Virus (M-MLV) reverse transcriptase, which is designed to reduce RNase H activity and create better thermal stability. This kit also contains RNAok™ RNase Inhibitor, which is active against RNase A, RNase B, and RNase C. This product is supplied with oligo (dT)20 and random hexamers, which are used to synthesize cDNA from poly(A) tailed mRNA and total RNA, respectively.
