G-Rk3's effects on the binding of fibrinogen. (A) The histograms of flow cytometry on the binding of fibrinogen. a, Intact platelets(base); b, collagen (2.5 μg/mL); c, collagen (2.5 μg/mL) + G-Rk3 (45 μM); d, collagen (2.5 μg/mL) + G-Rk3 (60 μM); e, collagen (2.5 μg/mL) + G-Rk3 (90 μM); f, collagen (2.5 μg/mL) + G-Rk3 (120 μM). (B) G-Rk3's effect on the binding (%) of fibrinogen induced by collagen.The results are shown as mean ± SD (n = 4). ap < 0.05 in comparison to no-stimulated platelets, ∗p < 0.05, ∗∗p < 0.001 in comparison to the collagen-induced platelets.
