Platelet adhesion onto immobilized fibrinogen, expressed as absolute fluorescence in pre- and postmenopausal women (n represents the number of tested subjects). Platelet adhesion at typical venous (50 s^-1) and arterial (500 s^-1 – 1500 s^-1) shear rates was tested at three different time points (15 sec, 1 min and 5 min). At each time point of perfusion a stack of 5 images was collected and analyzed. Finally 42 perfusion experiments were conducted and 630 images were analyzed.
