As a world leader in cell stabilization, Streck collection and preservation products protect sample integrity during extended periods of transportation and storage, ensuring preanalytical variables are controlled and the samples are protected.

  A blood collection tube for stabilization of cell-free plasma DNA, CTCs and cellular DNA. The preservative in Cell-Free DNA BCT stabilizes nucleated blood cells, preventing the release of genomic DNA, allowing isolation of high-quality cell-free DNA. Stabilizes cell-free DNA and cellular DNA for up to 14 days and CTCs for up to 7 days. Available in 10.0 mL and 2.0 mL tubes.
  A blood collection tube for sample collection, stabilization and transport of cell-free RNA. The patented preservative in Cell-Free RNA BCT stabilizes cell-free RNA in plasma and prevents the release of non-target background RNA from blood cells during sample processing and storage. Stabilizes cell-free RNA for up to 7 days at room temperature. Available in 10.0 mL tubes.
  A liquid reagent that stabilizes cell-free DNA all cellular components in urine, including red blood cells, white blood cells, and proteins present at the time of collection, allowing for additional downstream urinalysis. Cell-Free DNA Urine Preserve ensures sample integrity for prenatal and disease diagnosis as well as treatment efficacy and organ transplant rejection monitoring. Stabilizes urine samples for up to 7 days at room temperature.
  A direct-draw blood collection tube that preserves whole blood samples for immuno-phenotyping by flow cytometry. The preservative maintains the integrity of the white blood cell cluster of differentiation (CD) markers at room temperature for convenient transport and storage. FDA 510(k) cleared for consistent recovery of HIV associated lymphocyte subsets for up to 14 days. Available in 5.0 mL and 2.0 mL tubes.
  An easy-to-use liquid preservative that maintains cellular antigen expression, including cluster of differentiation (CD) markers and cell morphology of biological samples for analysis by flow cytometry. Streck Cell Preservative eliminates the adverse effects that time, storage and transport conditions can have on sample integrity. Stabilizes samples for up to 7 days. Available in 10.0mL and 1.0 mL vials.
