Effect of purified VN on in vitro platelet aggregation. Gel-filtered VN −/− platelets (2.0 × 108/mL) were incubated with thrombin (1 U/mL) in the absence (□) or presence (▪) of denatured human VN (200 μg/mL), and platelet aggregation was studied as described in Fig 3. Data points represent the mean of triplicate experiments ± 1 SEM.
