Gut microbiome

Stool sample collection

The Stool Collection Tubes with DNA Stabilizer are a versatile tool for gut microbiome analysis, microbiome associated disease research and nutrigenomics. It is designed for user-friendly stool sample collection and stabilization using a liquid stabilization buffer. After collection samples can be stored at room temperature without any cooling for up to three months. The product serves as an alternative to fast freezing of samples at -20°C/-80°C, α-diversity of bacteria is maintained in the DNA Stabilizer.

DNA extraction from stool samples

Stool is a complex sample type that contains a variety of potential inhibitors. To remove inhibitors, our extraction kits use the unique InviAdsorb matrix. Substances such as humic acid, phytochemicals and other digestive products bind to the matrix and are effectively removed. Sample extraction can be done from stabilized or fresh/frozen stool specimen.


For high sample throughput, the InviMag® Stool DNA Kit/ KF96 enables fast and cost-effective DNA purification using magnetic beads on the KingFisher™ Flex instrument.
