DNA/RNA Stabilization

DNA/RNA Stabilization

For best results, samples should be stabilized during transit and storage if there is a delay greater than 1-2 days between collection and processing of samples. Our stabilization products are designed to maintain complete molecular biology integrity while reducing cross contamination risks. 


  • Dri-Capsules - silica capsules compatible with SK-1S swabs that quickly and efficiently dry the swabs for instant stabilization. Dri-capsules stabilize DNA at room temperature for over 3 years. These capsules are sold in packs of 50 without swabs or in a kit with 50 SK-1S swabs.


  • BuccalFix DNA/RNA Stabilization Buffer - this buffer stabilizes DNA for 2 years and RNA for 4 days at room temperature and is offered in bulk or pre-filled in various tube formats to suit both manual and automated applications.


  • RapiDri Integrated DNA Swab Kit - pack of 200 swabs with stabilization pouches included. The special RapiDri pouches stabilize DNA for 3-6 months. RapiDri is an excellent alternative to longer-term stabilization at a lower cost.


  • StoolFix Stabilization Buffer - buffer optimized for fecal microbiome DNA. The buffer is pre-filled in tubes for minimal sample handling. DNA is stabilized for 2+ months at room temperature.
