title: Pr3+ transport across phosphatidylcholine vesicles mediated by open crown synthetic ionophores.
abstract: Pr3+ transport experiments, varying temperature and concentration, show that open crown synthetic polyethers (podands) mediate Pr3+ translocation across phosphatidylcholine vesicles by a carrier mechanism. Enhancement of the proton countertransport induced by addition of a protonophore, increases the cation inward rate.
