Functional reconstitution of a voltage-gated potassium channel in giant unilamellar vesicles. [PDF]
PLoS ONE, 2011 Voltage-gated ion channels are key players in cellular excitability. Recent studies suggest that their behavior can depend strongly on the membrane lipid composition and physical state. In vivo studies of membrane/channel and channel/channel interactions

Osmotic Gradients Induce Bio-reminiscent Morphological Transformations in Giant Unilamellar Vesicles [PDF]
Frontiers in Physiology, 2012 We report observations of large-scale, in-plane and out-of-plane membrane deformations in giant uni- and multilamellar vesicles composed of binary and ternary lipid mixtures in the presence of net transvesicular osmotic gradients.

Low-cost equipment for electroformation of Giant Unilamellar Vesicles [PDF]
HardwareX, 2018 Giant Unilamellar Vesicles (GUVs) constitute a very useful model for biomembranes. They are usually generated by electroformation using sinusoidal potential waves applied between two platinum electrodes or electrodes composed of glasses covered by indium

Law of corresponding states for osmotic swelling of vesicles [PDF]
Soft Matter, 2012; 8: 2185-2193, 2011 As solute molecules permeate into a vesicle due to a concentration difference across its membrane, the vesicle swells through osmosis. The swelling can be divided into two stages: (a) an "ironing" stage, where the volume-to-area ratio of the vesicle increases without a significant change in its area; (b) a stretching stage, where the vesicle grows ...

Endoplasmic reticulum phospholipid scramblase activity revealed after protein reconstitution into giant unilamellar vesicles containing a photostable lipid reporter [PDF]
Scientific Reports, 2021 Transbilayer movement of phospholipids in biological membranes is mediated by a diverse set of lipid transporters. Among them are scramblases that facilitate a rapid bi-directional movement of lipids without metabolic energy input. Here, we established a
