The authors took advantage of the fact that rats gavage-fed a large bolus of ethanol (single malt I hope) were observed to have their Golgi cisternae loaded with LDL particles. Since LDL particles are lighter than most other intracellular organelles, following homogenization of ethanol-fed rats, the Golgi fractions "floated" to the top of denser sucrose gradients during centrifugation. This allowed investigators to analyze the membrane properties of "pure" Golgi fractions and set the stage for development of fusion assays that led to an understanding of factors regulating the specificity of membrane fusion - the SNARE hypothesis. - Topics:
