Effect of different concentrations of TRAP on the platelet surface expression of GPIb and P-selectin. Orgaran anticoagulated whole blood (+ dRGDW) was incubated (5 minutes, 37°C) with various concentrations of TRAP. After 5 minutes, the blood was fixed in 1% paraformaldehyde, incubated with either MoAb 6.20 (against GPIb [▴]) or CD62 MoAb RUU-SP 2.17 (against P-selectin [•]), and analyzed by flow cytometry. Both the binding of the anti-GPIb MoAb before the addition of TRAP and the maximal binding of the anti-CD62 MoAb was assigned 100 arbitrary units of fluorescence. Data represent a typical experiment.
