Outer envelope membranes from chloroplasts are isolated as right-side-out vesicles [PDF]
, 1992 Outer envelope membranes were isolated from purified chloroplasts of pea leaves. The sidedness of the vesicles was analyzed by (i) aqueous polymer-two phase partitioning, (ii) the effect of limited proteolysis on the outer-envelope proteins (OEP) 86 and ...

Gram-Negative Bacteria’s Outer Membrane Vesicles
Infection & Chemotherapy, 2023 Outer membrane vesicles (OMVs) are spherical bilayered nanoparticles derived from the outer layer of Gram-negative bacteria. Bacteria communicate with nearby bacteria, their environment, and the cells of their host by secreting OMVs, which are essential for their survival.

Fusion of secretory vesicles isolated from rat liver [PDF]
, 1978 Secretory vesicles isolated from rat liver were found to fuse after exposure to Ca2+. Vescle fusion is characterized by the occurrence of twinned vesicles with a continuous cleavage plane between two vesicles in freeze-fracture electron microscopy.

A novel mechanism for the biogenesis of outer membrane vesicles in Gram-negative bacteria
Nature Communications, 2016 Bacteria release outer membrane vesicles (OMVs) that play important roles in pathogenesis and intercellular interactions. Here, Roier et al. provide evidence supporting that phospholipid accumulation in the outer leaflet of the outer membrane ...
