Elucidating membrane structure and protein behavior using giant plasma membrane vesicles

The observation of phase separation in intact plasma membranes isolated from live cells is a breakthrough for research into eukaryotic membrane lateral heterogeneity, specifically in the context of membrane rafts. These observations are made in giant plasma membrane vesicles (GPMVs), which can be isolated by chemical vesiculants from a variety of cell types and microscopically observed using basic reagents and equipment available in any cell...
