Fig 5. Effect of αB-crystallin on thrombin-induced formation of inositol phosphates in human platelets. The labeled cells were pretreated with various doses of αB-crystallin for 20 minutes and then stimulated by thrombin or vehicle for 10 minutes. The formation of inositol phosphates was then determined. Each value represents the mean ± SEM of triplicate determinations in a single experiments (representative of 3 experiments in all). * P < 0.05 vs the value of thrombin alone
