What makes up buffy coat

PBMCs, on the other hand, are individual fragmented lymphocytes and monocytes that separate from the rest of the whole blood sample through a process called density-gradient centrifugation. This process involves an additional density gradient that separates sample particles further based on their size and density.

By separating out granulocytes and platelets and creating a barrier between the WBCs and the RBCs, the sample is comprised of a more concentrated sample of monocytes and lymphocytes that can then be used for research or further isolated for specific downstream applications. Although the contents of a buffy coat already exist within a whole blood sample, they are not aggregated until centrifugation occurs. Before centrifugation, researchers should take a variety of precautions to ensure the extraction process is successful.

STREK tubes are commonly used for research looking to isolate DNA from blood, while EDTA tubes contain an EDTA anticoagulant used for processing whole blood samples without clotting, allowing for centrifugation into the different layers — including the buffy coat layer. The prepared whole blood sample is placed into a centrifuge to fractionate the buffy coat and separate it from the plasma and RBC. Using a small pipette, the experimenter collects the buffy coat and moves it to a separate container.

While PBMCs are separated from the other particles by a density gradient in the sorted sample, the buffy coat is in direct contact with isolated RBCs. To further enrich the buffy coat, researchers will often pair centrifugation with another method of cell separation , like BACS, to remove the residual RBC contamination.

BACS , or buoyancy activated cell sorting , is an innovative technology developed by Akadeum Life Sciences that uses functionalized microbubbles to isolate target cells. By attaching antibodies to the microbubbles that are specific to antigen-presenting cells in the sample, BACS can effectively target a specific type of cell and float it to the top for collection or removal. Traditional methods require expensive equipment, long processing times, and cause unnecessary cell death.

What i s the Buffy Coat? How is the buffy coat extracted from blood? Below is an example of a typical centrifugation process: Preparation Before the centrifugation process begins, the proper precautions must be taken.

Centrifugation Once all proper procedures have been followed, the sample is placed in the centrifuge machine, ensuring that the sample is balanced and properly secured.

Collection Using a pipette, the now concentrated leukocyte layer aka the buffy coat is extracted from the top of the centrifuged sample. What are the uses of buffy coat?

More often than not, researchers require isolated PBMCs, as opposed to buffy coats, since they are highly pure in mononuclear cells: lymphocytes and monocytes. Being both a provider of buffy coats isolated from whole blood units as well as a provider of isolated peripheral blood mononuclear cells PBMCs , BioIVT serves customers by offering a variety of different blood-derived immune cell products.
