Norgen's preservation tubes | Fast and easy method for collecting, preserving, and shipping stool samples at room temperature.
Preservation tubes for stool samples are a quick and easy way to collect, preserve, and ship them at room temperature.By stopping the growth of bacteria and fungi and deactivating viruses, it renders the sample non-infectious and gets rid of odor.
A consistent and dependable source of samples for metagenomics analysis or microbial detection using NGS, qPCR, ddPCR, and other techniques.Summary of community shifts in response to stabilizing solutions over a 14-day storage period. Bray-Curtis distance towards the reference for each patient grouped by stabilizing solution. Median and 5percentile ranges are shown for both interaliquot and interpatient variability . Norgen is the most similar to frozen stool samples, over 11 other sample collection and storage methods.Image Credit: Norgen Biotek CorporationDNA and RNA were isolated from 200 µL of preserved stool from 4 different donors stored at room temperature at the indicated time points using Norgen's Stool Nucleic Acid Isolation Kit . Next, 10 µL from the 75 µL eluted nucleic acid was loaded onto a gel for visual analysis. High-integrity stool DNA was isolated from preserved stool samples that were stored at room temperature for 27 months, and high integrity RNA was isolated from stool samples stored for 7 days at ambient temperature.

Monitoring the DNA stability of Adenovirus Spiked into Preserved Stool Samples using TaqMan Real-Time PCR Assay.pfu/mL of Adenovirus, and 200 µL samples were removed at the indicated time points. The stool DNA was then isolated using Norgen's Stool DNA Isolation Kit . Next, 2 µL of DNA template from each 50 µL of elution was used in a 20 µL PCR reaction to detect the Adenovirus DNA. The stool preservative was shown to stabilize Adenovirus DNA up to 21 weeks at ambient temperature, indicating that Norgen's Stool Nucleic Acid Collection and Preservation Tubes provide a safe and convenient sample transportation system.

The microbial composition from the stool samples preserved in Norgen’s Stool Nucleic Acid Collection and Preservation Tubes did not differ significantly to that of controls over a 2 day period while non-preserved stool samples showed a distance in the dendrogram from the original stool profile. Image Credit: Norgen Biotek CorporationAbundance of Firmicuties, Bacteroidetes, and proteobacteria from the preserved stool sample was higher than non-preserved to the fresh stool after 2 days storage at RT, indicating that the originality of microorganism profile from the preserved are much closer to the fresh stool sample .

Preserved stool sample using Norgen’s Stool Nucleic Acid Collection and Preservation Tubes showed closed relativeness to the fresh stool sample . Image Credit: Norgen Biotek CorporationCorrelation between duplicate bacterial metagenomic reads using Fresh stool and preserved stool at RT for 2 days and Fresh stool and non-preserved stool at RT for 2 days. A greater R2 was observed for Fresh stool and preserved stool, suggestive of higher consistency between fresh stool sample and preserved stool sample. Image Credit: Norgen Biotek CorporationAll tubes should be stored at room temperature with a tight seal for two years following the date of shipment to prevent performance degradation.To start a conversation, please log into your AZoProfile account first, or create a new account.I understand, and agree to receive occasional emails about Azthena such as usage tips and new feature announcements.While we only use edited and approved content for Azthena answers, it may on occasions provide incorrect responses.
