Dose-dependent ristocetin-induced inhibition of human platelet agglutination by S-nitroso-AR545C and AR545C. Formalin-fixed platelets (2 × 108/mL) were incubated with either AR545C (▪) or S-nitroso-AR545C (•) for 10 minutes at various concentrations followed by addition of normal PPP and 1.5 mg/mL ristocetin.
