Inhibitory effect of ALX-0081 on in vitro platelet adhesion to collagen type III. Whole blood preincubated with (●) or without (□) ALX-0081 was perfused for 5 minutes over a surface coated with human collagen type III after which the percentage surface coverage was measured. Mean values ± SEM for 3 independent repeats are shown. (A) Percentage surface coverage in function of shear rate. Concentration of ALX-0081 was 0.8 μg/mL. (B) Percentage surface coverage in function of ALX-0081 concentration. Shear rate was 1600 s⁻¹.
