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.
