Cell-Free DNA BCT® RUO
Cell-Free DNA BCT CE
Cell-Free DNA BCT is a blood collection tube that stabilizes cell-free DNA for up to 14 days at 6 °C to 37 °C* and CTCs for up to 7 days at 15 °C to 30 °C*. It is available as a CE marked in vitro diagnostic device or as a Research Use Only tube, depending on region of use.
*These performance characteristics have not been evaluated by the U.S. Food & Drug Administration
Product Description
Cell-Free DNA BCT maintains cell-free DNA for up to 14 days at 6 °C to 37 °C* and CTCs for up to 7 days at 15 °C to 30 °C*. It contains a preservative reagent that limits the release of genomic DNA, allowing for isolation of high-quality cell-free DNA, and minimizes the degradation of circulating tumor cells (CTCs)*. Cell-Free DNA BCT eliminates the need for immediate plasma isolation and CTC processing, easing concerns about pre-analytical variation that arises during shipping and handling.
The cell-free DNA and CTCs isolated from stored plasma are suitable for many downstream applications used in research studies, drug discovery and assay development.
