Figure 5. Effect of AnSt-D7L1 on platelet aggregation promoted by different agonists.

Figure 5

Platelet-rich human plasma was incubated with different concentrations of AnSt-D7L1 for 1 min prior to the addition of agonists as indicated. Aggregation was measured at 37°C on an aggregometer. Unless otherwise stated protein concentration (µM) is shown under respective curves. (A) Concentration dependence of AnSt-D7L1 inhibition of collagen-mediated platelet aggregation at low concentration of collagen. (B) Lack of inhibition of collagen-mediated platelet aggregation by AnSt-D7L1 at high concentration of collagen. (C) Lack of inhibition of convulxin-mediated platelet aggregation by AnSt-D7L1. (D) ADP-mediated platelet aggregation in the absence of any protein (control), in the presence of 3 µM AnSt-D7L1, or in the presence of 3 µM RPAI1, which is known to bind ADP. (E) Lack of effect of AnSt-D7L1 on PMA-induced platelet aggregation. (F) Lack of effect of AnSt-D7L1 on ristocetin-induced platelet aggregation.
