The quantal characteristics of the catecholamine-containing granules were not altered by α-SNAP.A, Plot of the quantal charge (Q) of individual amperometric events. Q was calculated from the time integral of each signal. Each histogram compared the events from control cells with events from cells dialyzed for at least 4 min with 500 nm α-SNAP. In all experiments, [Ca2+]i was buffered to ∼170 nm. B, Plot of the cube root ofQ (Q1/3). α-SNAP caused no statistical difference in the distribution ofQ (Mann–Whitney U test) orQ1/3 (Student's ttest).
