Normal expression of (A) CD62 and (B) CD63 on vWF-deficient platelets in vWF-deficient plasma and control platelets in control plasma, induced by CRP-XL, measured by flow cytometry using FITC-labeled anti-CD62 antibody or anti-CD63 antibody, respectively. Fluorescence of unstimulated control platelets is defined as 1. Data shown are representative of two similar experiments.
