Single-file diffusion multi-ion mechanism of permeation in paracellular epithelial channels


The transepithelial fluxes, conductances and permeabilities of Li+, Na+, K+, Cs+, NH 4 + and H3CNH 3 + were studied under ionic concentrations ranging from 12 to 250mm inBufo arenarum gallbladders. When these measurements are carefully corrected in order to get only the component due to the paracellular cation channels, the following results are obtained… (More)
