Effect of different Ca2+ buffers on Ca2+-independent exocytosis compared with Ca2+-stimulated exocytosis. (A) Example traces illustrating changes in Cm for 20 min after the start of cytosolic dialysis with 1 μM free Ca2+ (top trace), or with no added Ca2+ and addition of Ca2+ buffers as indicated. Numbers at start of traces indicate resting capacitance (in pF) measured upon formation of the whole-cell configuration. (B) Average relative changes in Cm (% Cm) determined 20 min after the start of cytosolic dialysis with 1 μM free Ca2+ (n = 8), 8 mM EGTA (n = 4), 20 mM BAPTA (n = 10), or 20 mM dibromo-BAPTA (n = 7). Bars represent SEM.
