Fig 1. Effect of αB-crystallin on platelet aggregation in vitro using human platelets. The aggregation of platelets stimulated by botrocetin (3.3 μg/mL) using PRP (a) or thrombin (0.3 U/mL) using washed platelets (b) was performed after preincubation for 20 minutes with αB-crystallin or vehicle. Each value represents the mean ± SEM of triplicate determinations. * P < 0.05 vs the value of botrocetin alone, ** P < 0.05 vs the value of thrombin alone
