WebPlatelet-Poor Plasma (PPP) is blood plasma with very low number of platelets (< 10 X 10 3 /μL). Traditionally, PPP was recommended for use in platelet aggregation studies to both adjust the Platelet-rich plasma concentration, and to serve as a control. PPP may have elevated levels of fibrinogen, which has the ability to form a fibrin-rich clot once activated. WebSpecifically, in the platelets from SLE patients, the addition of TRAP increased the average fraction of P-selectin-positive platelets from 2.5% before to 33% after TRAP stimulation, while in control samples, the average fraction of platelets expressing P-selectin increased from 1.5% to 73% after TRAP stimulation.
