Representative flow cytometry dot plots depicting fluorescence intensity (anti-IIb antibody Tab-FITC) versus forward scatter intensity of platelets and PMPs.

The following are depicted: (A) PRP from freshly drawn blood; (B) PPP that has been centrifuged 3 times at 1250g; (C) PRP from blood that has been stored for 5 days; and (D) PPP from stored blood. The vertical gate was drawn to identify particles less than approximately 1 μm in size, and the horizontal gate was drawn at a fluorescence intensity above the background level. Events were collected for 90 seconds for all cases.
