FIGURE 2.
Flow cytometric analysis of platelet-derived microparticles shed after pre-incubation of platelets with eptifibatide (10 μg/mL) and stimulation with different platelet agonists. Dot plots show the dual fluorescence analysis of representative PFP stained with Annexin V-FITC and anti-CD61-phycoerythrin (PE). The total number of CD61+ events was calculated as the sum of CD61+/Annexin and CD61+/Annexin + events. Absolute counts of PMPs were determined by using Flow-CountTM Fluorospheres and expressed per microliter of PFP. Experiments were performed in duplicate.
