DNA Stabilization

DNA 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 DNA 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 Stabilization/Lysis Buffer - this buffer stabilizes DNA at room temperature for 2 years and are offered in bulk or pre-filled in various tube formats to suit both manual and automated applications.
