Studies on the fusion of phospholipid vesicles have provided considerable insight into the
molecular mechanism of membrane fusion and the role of specific molecules in this process …

Divalent cation-induced fusion of large unilamellar vesides (approx. 0.1 μm diameter) made
of phosphatidylserine (PS) or phosphatidylglycerol (PG) has been studied. Intermixing of …

We have investigated the contribution of various phospholipids to membrane fusion induced
by divalent cations. Fusion was followed by means of a new fluorescence assay monitoring …
