Nucleic Acid BCT

Nucleic Acid BCT is a direct draw venous whole blood collection device that maintains draw-time concentrations of cell-free DNA, cell-free RNA and extracellular vesicles for up to 7 days when stored at room temperature. Plasma yield is maximized and hemolysis is minimized during storage. Once isolated from stored plasma, cell-free DNA and cell-free RNA are suitable for many downstream applications.

Nucleic Acid BCT is currently available in a 5 mL volume. 10 mL volume is coming soon.

Nucleic Acid BCT Preanalytical workflows


  • Stabilizes sample for cell-free DNA, cell-free RNA and extracellular vesicles
  • 7-day sample stability when stored at room temp
  • Compatible with commercially available total plasma nucleic acid isolation kits


  • Limits degradation of white and red blood cells, providing sample integrity during storage, shipping and handling of blood samples
  • Room temperature storage reduces costs and complications associated with cold chain shipping
  • Eliminates the need for immediate plasma preparation
  • Reduces hemolysis and increases plasma yield after storage compared to alternative blood collection tubes
  • One plasma isolation protocol for both cell-free DNA and cell-free RNA
