Materials and Methods The procedures used for the preparation and purification of pure
DMPC, DMPS, DEPC, DEPS, DOPC, and DOPS, for the calorimetric analysis of lipid …

Sonicated unilamellar liposomes containing phosphatidylethanolamine and
palmitoylhomocysteine fuse rapidly when the medium pH is lowered from 7 to 5. Liposome …

Polylysine induced aggregation and fusion of negatively charged small unilamellar
phosphatidylcholine vesicles containing at least 10% anionic lipid. Aggregation was …

Materials and Methods Materials. Peptides were synthesized as described (Tak-ahashi,
1990). The peptide concentration was determined from the absorbance at 280 nm using …

Membrane fusion induced by Ca 2+ and Mg 2+ in large unilamellar vesicles composed of
mixtures of phosphatidylethanolamine with phosphatidate and phosphatidylinositol was …

Sonicated vesicles of 20–50 nm in diameter consisting of neutral phospholipids and a
variety of acidic phospholipids were interacted with polylysine, cytochrome c, Ca 2+ and Mg …

The interaction of phosphatidylserine vesicles with Ca 2+ and Mg 2+ has been examined by
several techniques to study the mechanism of membrane fusion. Data are presented on the …

Fusion between vesicles prepared from individual or mixed phospholipid species was
demonstrated by ultracentrifugation and gel-filtration techniques, electron microscopy and …

Determination of the mechanisms by which cationic liposomes adhere to and fuse with
biological membranes is important to understanding how these lipid vesicles mediate …
