(A) Concentration dependence of k (see Eq. 1), the “on” rate constant of G3139-induced rapid flickering of a single VDAC channel at −50 mV. The error bars shown are the standard errors of a single experiment generated by QuB. The equation in the graph is the result of a linear fit. (B) Voltage dependence of k₁. The error bars shown are the standard errors of the slope calculated from the linear regression in the concentration dependence curve. The equation in the graph is the result of an exponential fit. These results are typical of three independent experiments.
