摘要：

The ionophore A23187 was incorporated into the lipid bilayer of unilamellar vesicles and used to earry externally added indium ions to a chelator, nitrilotriacetic acid, which was previously entrapped in the vesicles. The extent of vesicle loading was assayed by Sephadex chromatography and γ-ray perturbed angular correlation spectroscopy. Incubation conditions were developed which allow rapid loading of more than 90% of added 121In3+ with specific activities of 200-300 μCi/mg lipid. © 1979.
