WebFluorescence Loss in Photobleaching (FLIP) is a fluorescence microscopy technique used to examine movement of molecules inside cells and membranes. A cell membrane is typically labeled with a fluorescent dye to allow for observation. A specific area of this labeled section is then bleached several times using the beam of a confocal laser … WebFinally, it is possible for phospholipids to move between both leaflets of the bilayer in transverse movement, in a “flip-flop” manner. Phospholipids in the lipid bilayer can either move rotationally, laterally in one bilayer, or …
