Figure 3.

Increase of stable platelet adhesion onto immobilized fibrinogen under different shear rates (50 s^-1, 500 s^-1 and 1500 s^-1) with regard to the HPA-1 polymorphism within the first 45 seconds of perfusion (Fig. A, "initial phase") and between 1 and 5 min of perfusion ("late platelet adhesion"). Each bar represents mean value ± SE. The relative adhesion represents the increase of absolute fluorescence in function of time (absolute fluorescence recorded after five minute of perfusion was divided by recorded fluorescence after 1 minute or after 15 sec of perfusion).
