Fluorescent indicators sensitive to cytosolic concentrations of free Na+ have been synthesized and characterized. They consist of a crown ether, 1,7-diaza-4,10,13-trioxacyclopentadecane, linked via its nitrogens to fluorophores bearing additional liganding centers. In the currently preferred dye, SBFI (short for sodium-binding

Although the predominance of plasmalogens in electrically-active membranes (e.g., sarcolemma) is well-known, identification of the molecular mechanisms through which the vinyl ether linkage facilitates electrophysiologic function has remained elusive. Herein we demonstrate that the kinetics of both carrier-mediated (i.e., valinomycin)
