Abstract:The effect of defects in a dipalmitoylphosphatidylcholine (DPPC) membrane on Ca 2+ permeability across the membrane was studied. Addition of teleocidin to a suspension of DPPC vesicles encapsulating Quin 2 increased the fluorescence intensity of Quin 2. Change of fluorescence intensity was significant below the phase-transition temperature of the membrane, and increased according to the kind of divalent metal ions in the medium in the order of Mg 2+ < Ba 2+ < Ca 2+. It was confirmed that DPPC vesicles did not … Show more
