Effect of ADP addition on collagen plus thrombin-induced [Ca2+]i responses. Changes in [Ca2+]i in stirred, collagen plus thrombin–stimulated fura-2–loaded GFP with 5 μmol/L ADP (+ADP) or elution buffer (−ADP) added 30 seconds after stimulation. Results are shown for five normal subjects (A) and six δ-SPD-HPS patients (B). The [Ca2+]i values are plotted as described for Fig 3.
