Positively charged albumin is described as a 'useful tool' to induce both aggregation and fusion of phosphatidylcholine vesicles containing sulfatide. Techniques that include light-scattering, Sepharose chromatography, centrifugation, electron microscopy, trapped volume determination and scanning calorimetry demonstrate that extensive fusion occurs during aggregation when sulfatide concentrations are above 4-5 mol%. The rate of fusion increases with time for 1-2 h, then reaches a plateau. Fusion occurs extensively above the transition temperature of the phospholipid and is strongly inhibited by increasing concentration of vesicle cholesterol. The significance of both membrane fluidity and sulfatide-phospholipid organization in the fusion mechanism are discussed.
