Sample Collection & Preservation

Sample collection and preservation tubes that stabilise RNA and DNA without cold chain

Nucleic acids in saliva, urine, stool, blood, and swab specimens start degrading within hours at room temperature once collected. Collection and preservation devices inactivate nucleases at the point of collection, so RNA and DNA stay stable at ambient temperature for extended periods and you can ship samples without dry ice. Non-invasive saliva collection formats suit self-administered collection for large-cohort studies and home-sampling programmes, while swab tubes preserve microbial and human nucleic acids from nasal, buccal, and vaginal swabs. Cell-free DNA and RNA preservative tubes stabilise circulating nucleic acids in blood plasma without centrifugation at the collection site.

Pick by biomolecule.

1. RNA. RNAlater-equivalent buffers or dry-collection cards.
2. DNA. Sample-type-specific ambient-temperature buffers for saliva, urine, blood spot, stool.
3. Protein. Protease-inhibitor-containing buffers.
4. Viable cells. Cryopreservation media.
5. Multi-site studies. Ambient-temperature stabilisers remove cold-chain failure as error source.
