BCT & PRESERVATIVES

Collection and preservation products protect sample integrity during extended periods of transportation and storage, ensuring preanalytical variables are controlled and the samples are protected.

BLOOD COLLECTION TUBES (BCT):

BCT is reducing the need for immediate plasma preparation due to its unique stabilization properties.

• cell-free DNA BCT: direct-draw venous whole blood collection device intended for the collection, stabilization and transport of venous whole blood samples for use in conjunction with cell-free DNA next generation sequencing assays.
• Nucleic acid BCT: 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.
• Protein plus BCT: direct draw whole blood collection tube intended for the stabilization of draw-time concentrations of plasma proteins for up to 5 days* at ambient temperature.
• Cyto-Chex BCT:  direct draw blood collection tube that maintains cellular morphology and surface antigen expression, including cluster of differentiation (CD) markers, prior to analysis by flow cytometry.

STABILIZATION REAGENTS:

• Streck Cell Preservative is an easy-to-use liquid preservative that maintains white blood cell integrity and allows CD markers to be measured through flow cytometric analysis.

• Streck Urine Preserve is a ready-to-use liquid reagent that stabilizes nucleic acid targets in urine for up to 7 days at 6 °C to 37 °C to limit changes associated with sample handling, shipping and field collection.
