Reconstitution into liposomes of the glycoprotein of vesicular stomatitis virus by detergent dialysis. 1979

W A Petri, and R R Wagner

The glycoprotein of vesicular stomatitis (VS) virus was selectively liberated from the virion membrane by the dialyzable nonionic detergent, beta-D-octylglucoside. The isolated viral glycoprotein could be rendered virtually free of phospholipid and detergent, under which conditions it formed tail-to-tail glycoprotein micelles in the form of rosettes. When mixtures of viral glycoprotein and egg lecithin were dialyzed free of octylglucoside, glycoprotein vesicles formed spontaneously with spikes protruding in the same external orientation as the VS virion membrane. The glycoprotein vesicles exhibited increased and uniform buoyant density, indicating relative homogeneity in the proportion of glycoprotein and phosphatidylcholine in each glycoprotein liposome. Evidence for similar insertion and orientation of VS viral glycoprotein in both phosphatidylcholine vesicles and virion membrane was substantiated by the finding that proteolytic digestion with thermolysin gave rise to hydrophobic glycoprotein tail fragments in vesicle or virion membranes that migrated identically in polyacrylamide gels.

UI	MeSH Term	Description	Entries
D008081	Liposomes	Artificial, single or multilaminar vesicles (made from lecithins or other lipids) that are used for the delivery of a variety of biological molecules or molecular complexes to cells, for example, drug delivery and gene transfer. They are also used to study membranes and membrane proteins.

D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
