[Coupled transport of K+, Cl-, H+ and OH- ions in a liposome suspension].
By means of the system of ion-selective electrodes the coupling transport of K+, H+ and Cl- ions in liposome suspension was studied. Nigericin and tributyl tin (TBT) were used as inductors of cation and anion exchange. Effect of pH gradient created on the membrane on ionic transport was studied. The latter was shown to control the antiport exchange of both, cations and anions. At the joint effect of nigericin and TBT the yield of K+ and Cl- ions from liposomes independent of the pH gradient was observed.
