Ristocetin-induced binding to platelets of plasma vWF from 8 patients.
Normal plasma or patient plasma vWF was indirectly labeled with 125I-labeled anti-vWF mAb and then incubated with fixed platelets in the presence of ristocetin. The binding was expressed as the percentage of platelet-bound radioactivity to total radioactivity. Results represent the mean of 2 experiments.
