Stimulation of gastric parietal cells results in exocytic recruitment of the proton pump (H+, K+-
ATPase) from a pool of intracellular membranes (tubulovesicles) to the apical plasma …

We demonstrate that there are two experimentally distinguishable steps in the fusion of
phospholipid vesicles with planar bilayer membranes. In the first step, the vesicles form a …

Exocytic activation of gastric parietal cells represents a massive transformation. We studied
a step in this process, homotypic fusion of H, K‐ATPase‐containing tubulovesicles, using …

Cell-free fusion between endocytic vesicles has been obtained in a sensitive assay based
on the avidin-biotin binding reaction. Chinese hamster ovary cells are allowed to …

Ricin, a plant toxin that binds to galactose‐terminated glycoproteins and glycolipids on the
cell surface, is internalized into endosomes before reaching the cytosol where it exerts its …

Fluorescence microscopy combined with electrical conductance measurements were used
to assess fusion of phospholipid vesicles with a planar bilayer. Large unilamellar vesicles …

A sensitive, quantitative assay has been developed which measures the extent of liposome
fusion by monitoring fluorescence resonance energy transfer between two lipid analogs …

A new assay has been developed for vesicle-vesicle fusion based upon the mixing of
intravesicular contents of two sets of vesicles. Purified firefly luciferase and MgCl 2 were …

Fusion of intracellular vesicles with the plasma membrane, resulting in the extracellular
discharge (exocytosis) of vesicular contents, plays a prominent role in a plethora of …
