The band 3 protein‐mediated, valinomycin‐induced KCl efflux continues to increase with increasing [KCl] when the Cl − /Cl − equilibrium exchange becomes saturated. This suggests the existence of a band 3‐mediated component of Cl − flux that contributes to the electrical conductance without being related to slippage; i.e., equilibration of the unloaded transport protein between the two membrane surfaces.
