BD Vacutainer® CPT™ Cell Preparation Tube with Sodium Heparin

Test Principles

This product is an evacuated tube system containing Sodium Heparin anticoagulant and blood separation media composed of a thixotropic gel and a FICOLL™ HYPAQUE™ solution.

The Tube's internal vacuum allows blood to be drawn in during venipuncture. Sodium heparin provides anticoagulation.

The blood separation media takes advantage of the lower density of mononuclear cells and of platelets to isolate them from whole blood. The isolation occurs during centrifugation when the gel portion of the media moves to form a barrier under the mononuclear cells and platelets; this separates them from the denser blood components below. Later, additional washing and centrifugation steps reduce the quantity of platelets present, resulting in a suspension of concentrated mononuclear cells.
