Let the blood sit for 30 minutes to one hour A buffy coat suspension is a concentrated suspension of leukocytes and platelets that make up a part of the anticoagulated blood sample obtained by the process of density gradient centrifugation. The term buffy coat arose from the fact that the suspension has a color (yellowish beige) that is similar to buff. Buffy coats primarily contain white blood cells and platelets when separated from the whole blood sample via centrifugation. 6. Using a 5 mL serological pipette tip and autopipettor carefully transfer the plasma layer from the vacutainer tubes into 15 mL tubes (combine plasma from two vacutainer tubes into one 15 mL tube), leaving a layer of approximately 0.5 mL of plasma behind.
