A, Platelet free citrated-plasma was treated with 1 μg/mL fluorescently labeled anti-vWF and 5 mM EDTA. The plasma samples were perfused over a collagen type 1 surface at local wall shear rates of 30,000, 62,400 and 125,000 s−1 from left to right. Long fibers of vWF (>20 μm) appeared at shear rates above ∼30,000 s−1, with more fibers appearing at higher shear rates. The bar indicates 15 μm.
