What is the intended use of the BD Vacutainer® CPT™ Tube?
The BD Vacutainer® CPT™ Cell Preparation Tube (BD CPT™ Tube) with sodium citrate or sodium heparin is an evacuated tube intended for the collection of whole blood and the separation of mononuclear cells. The cell separation medium is comprised of a polyester gel and density gradient liquid. This configuration permits cell separation during a single centrifugation step. The separated sample can be transported without being removed from the BD CPT™ Tube since the gel forms a stable barrier between the cell layers.
