Effect of β-SNAP. Plot of the mean of the cumulative number of amperometric events recorded in individual cells dialyzed with β-SNAP (500 nm) alone (●) or simultaneously with α-SNAP (500 nm, ○). The experimental conditions were similar to those in Figure 1. The data from cells dialyzed with 500 nm α-SNAP (▵ withdashed line; from Fig. 2D) and the linear regression for the data from control cells (with no α- or β-SNAP; solid line) were included for comparison. All data points for β-SNAP alone were not statistically different from control, but all data points between the 6th and 13th minute of dialysis of α- and β-SNAP were statistically different from control (the linear regression of these data points had a slope of 3.1;r = 0.99).
