Streck Cell-Free DNA BCT

Last updated: 14th January, 2021

Streck Cell-Free DNA BCT® is a blood collection tube with a preservative stabilizing nucleated blood cells. This unique stabilization prevents the release of genomic DNA, allowing isolation of high-quality cell-free DNA. It also has been demonstrated to minimize the degradation of CTCs.

Multiple Applications

Recover high-quality cell-free DNA suitable for a wide range of downstream applications commonly used in clinical research studies, drug discovery and diagnostic assay development.

Consistent Results

Enhanced stability and recovery of cell-free plasma DNA minimizes variability associated with cell-free DNA sample preparation.

Improved Logistics

Cell-Free DNA BCT reduces the need for immediate plasma preparation and CTC processing due to unique stabilization properties. Cell-free DNA is stable for up to 14 days at 6 °C to 37 °C, while circulating tumor cells are stable for up to 7 days, at room temperature, allowing convenient sample collection, transport and storage.
