Scott syndrome platelets display normal convulxin (Cvx)-/thrombin (Thr)-induced Ca²⁺ responses. (A-B) Time drive of fluorescence increase of washed control (A) and Scott syndrome (B) platelets loaded with Fluo-4 and activated by Cvx/Thr (70 ng/mL, 4 nM) in the presence of 2 mM CaCl₂. (C) Average change in mean fluorescence intensity (MFI), representing cytosolic Ca²⁺, after 10 min stimulation. n.s., not significant.
