Divalent cation (Ca 2Γ· and Mg 2Γ·) and hydrogen ion-induced fusions of small unilamellar phosphatidic acid vesicles were studied by the use of fluorescence fusion assay. These fusogenic ions also increased interracial tension and reduced the surface dielectric constant of phosphatidic acid membranes
Ca2\*-induced lateral phase separation in an equimolar ternary mixture of dipalmitoylphosphatidic acid (DPPA), dipalmitoylphosphatidylcholine (DPPC) and dimyristoylphosphatidylethanolamine (DMPE) was investigated by high-sensitivity differential scanning calorimetry. The thermogram showed a merged p
