Parameters describing the best fit of a modified Boltzmann equation to the I-V plot for the indicated conditions
The values were obtained from a statistical analysis of values obtained from a fit of a modified Boltzmann function as stated under “Experimental Procedures.” There is no statistical difference in either V½ or the slope (k). Cyt D, cytochalasin D.
