Cell-Free DNA BCT is a blood collection tube with a formaldehyde-free preservative stabilizing nucleated blood cells. This unique stabilization prevents the release of genomic DNA, allowing isolation of high-quality cell-free DNA which can be further used for a wide range of downstream applications in clinical research studies, drug discovery and diagnostic assay development. It has also been demonstrated to minimize the degradation of CTCs.


Cell-Free DNA BCT reduces the need for immediate plasma preparation and CTC processing due to its unique stabilization properties. Cell-Free DNA is stable for up to 14 days, while circulating tumor cells are stable for up to 7 days, at room temperature, allowing convenient sample collection, transport and storage.
