The ion transport current was clearly observed across a bilayer lipid membrane (BLM) between two aqueous phases (W1, W2) containing 0.1 M CsCl. In addition, the current density at a given potential between W1 and W2 increased using I instead of Cl as the counter ion. Our results strongly suggest that the cell membrane transport is partially responsible for the internal exposure of Cs and Cs.
