Inhibition of aggregation of washed platelets induced by vWF or alboaggregin A.
Upper curves: washed human platelets (500 μL, 5 × 108/mL) were stirred at 1100 rpm at 37°C and aggregation was induced by 5 μg/mL human vWF plus 0.5 mg/mL ristocetin (A) or by 0.1 μg/mL alboaggregin A (B). Lower curves: washed human platelets (500 μL, 5 × 108/mL) were stirred in the presence of 20 μg/mL echicetin, and the same agonists (A and B) were added after 1 minute.
