Blood Separation Techniques: How to Separate Plasma From Blood

A blood apheresis machine receives blood that is extracted from a patient's body and sorts it into plasma, platelets, WBCs, and RBCs. This device can be helpful when consistently dealing with large samples of whole blood, but for smaller experiments or T cell isolation assays, a blood apheresis machine is not cost-effective.
