Correlation between the results obtained by flow cytometric evaluation of platelet activation parameters and VerifyNow-P2Y
test in patients receiving antiplatelet therapy. The percent of inhibition (% inhibition) was plotted against the percentage of platelets that expressed bound PAC-1 after stimulation with 20 μM ADP and 5 μg/mL collagen type I for 110 min at room temperature in the presence of 1 μM PG E1. (§) First quartile of control values for PAC-1 binding. The others abbreviations as reported in the Figure 2.
