Product details
The BD Vacutainer® CPT™ Mononuclear Cell Preparation Tube with Sodium Heparin is a specialized blood collection tube designed to simplify the isolation of peripheral blood mononuclear cells (PBMCs) for diagnostic and research use. Manufactured by Becton, Dickinson and Company, this tube combines an anticoagulant with a gel density gradient and polyester resin barrier to enable rapid, consistent cell separation during centrifugation.
The CPT™ tube streamlines sample processing by allowing blood collection and cell separation in a single closed system, reducing handling time and minimizing contamination risk. With dimensions of 16 x 125 mm and an 8.0 mL draw volume, it is ideal for clinical laboratories, immunology studies, flow cytometry, and molecular testing.
Key Features & Benefits:
-
Contains sodium heparin anticoagulant to preserve cell integrity
-
Integrated density gradient and barrier for efficient PBMC separation
-
Single-tube system reduces processing steps and contamination risk
-
Consistent and reproducible cell recovery
-
Ideal for clinical research, immunology, and diagnostic laboratories
The BD Vacutainer® CPT™ Mononuclear Cell Preparation Tube offers a convenient and reliable solution for high-quality cell isolation, improving laboratory efficiency and sample consistency.
BD Vacutainer® CPT™ is a fully-closed system for separation of mononuclear cells from whole blood, where cell separation is carried out in the primary blood collection tube. This decreases the complexity of steps for mononuclear cell separation, thereby minimizing variability from sample processing.
CPT™ is an evacuated, sterile blood collection tube containing buffered sodium citrate or sodium heparin anticoagulant, liquid density medium and an inert gel barrier. It is intended for the collection of whole blood and the subsequent separation of mononuclear blood cells for the purposes of in vitro diagnostic examination.
Whole blood is drawn directly into the CPT™ using standard phlebotomy techniques and processed in the same tube. During centrifugation, the gel forms a physical barrier between the mononuclear cells in plasma and the erythrocytes and granulocytes. The separated, concentrated suspension of mononuclear cells in plasma can then be transported in the primary blood collection tube.
