Collecting samples for microbiome profile analysis
Appropriate preservation and storage of stool samples is crucial in maintaining DNA fidelity and microbial community composition for downstream applications and analysis, including next-generation sequencing (NGS) and microbiome characterization. Post-collection bias may be introduced in cases where sample material is inadequately preserved, highlighting the importance of preservation in study design. Currently, rapid freezing to -80°C is considered best-practice for preserving stool samples; however, this modality may be unfeasible when sample collection takes place in non-laboratory settings, such as in participants’ homes.
In such instances, using a stool collection device that includes a specialized preservative offers a solution. Ideally, such a preservative does not only protect DNA and RNA but also stops bacterial growth as well as inactives any virus to allow safe shipping.
Collect & preserve stool samples for unbiased results
Norgen Biotek's Stool Nucleic Acid Collection and Preservation products allow for an easy sample collection followed by successful preservation of the microbiota profile (Application note 91 - Comparative microbiome profile from different preservation methods).
- Easy and user-friendly sample collection
- Stabilize the microbiome profile & allow safe transport at room temperature
- Prevent microbial growth
- Inactive viruses
- Maintain the original microbiome profile
- Store DNA for up to 2 years at room temperature
- Store RNA for up to 7 days at room temperature
- Compatible with most commercially available DNA and RNA isolation kits
- For use with sensitive downstream applications incl. NGS, qPCR, genotyping and more
This stool nucleic acid preservation system is available in tube with spoon formats (tubes, individual clamshells, or Dx), and a swab format. The preservative is included in liquid form.
Norgen Biotek products can also be ordered through LubioScience on many university online catalogs.
