Frequently asked questions
What is the difference between the sodium citrate CPT tube and the sodium heparin tube?
The choice of anticoagulant depends on the downstream application. Sodium citrate is generally preferred for coagulation studies and certain cellular functional analyses, while sodium heparin is suitable for other types of analyses. Consult your laboratory protocol to determine the appropriate tube.
How does mononuclear cell separation work in the BD Vacutainer CPT tube?
During centrifugation, the density medium and gel barrier allow separation of blood components according to their density. Mononuclear cells remain in the plasma layer above the gel, while erythrocytes and granulocytes pass under the gel barrier.
Can BD Vacutainer CPT tubes be transported after collection?
Yes, after centrifugation, the concentrated suspension of mononuclear cells in plasma can be transported directly in the primary collection tube. The closed system facilitates secure handling and transport of samples.
