Inhibition of [Ca²⁺]_i mobilization by apigenin. A representative example of interference of [Ca²⁺]_i mobilization by some flavonoids. Oregon Green BAPTA-1 AM-loaded platelets were stimulated with 2 µm U46619 in the absence or in the presence of increasing concentrations of apigenin and [Ca²⁺]_i mobilization was recorded vs. time as stated in Materials and methods. The arrow indicates the addition of agonist
