1 Effect of calcium ion concentration on the ability of fibrinogen and von Willebrand factor to support the ADP-induced aggregation of human platelets. Adenosine Diphosphate von Willebrand factor Homo sapiens
2 In the low calcium medium, either vWf or fibrinogen supported biphasic aggregation in response to ADP, with thromboxane formation and release of granule contents. Adenosine Diphosphate von Willebrand factor Homo sapiens
3 Although vWf supports ADP-induced aggregation when the concentration of ionized calcium is in the micromolar range, it does not support ADP-induced aggregation in the presence of a concentration of ionized calcium in the physiological range, indicating that vWf probably cannot substitute for fibrinogen in supporting ADP-induced aggregation in vivo. Adenosine Diphosphate von Willebrand factor Homo sapiens
