Synergistic effects in PR3+ transport mediated by ionophores across phosphatidylcholine vesicles.
Use of a fluorescent probe for the intravesicular pH shows that synergisms previously observed in Pr3+ transport across phosphatidylcholine vesicles are explained by an increase in the proton counter-transport.
