FLIP is often used and is closely associated with Fluorescence recovery after photobleaching (FRAP). The major difference between these two microscopy techniques is that FRAP involves the study of a cell’s ability to recover after a single photobleaching event whereas FLIP involves the study of how the loss of fluorescence spreads throughout the cell after multiple photobleaching events.

WebOct 26, 2015 · These flippases, or phospholipid translocators, use ATP to move lipids across the bilayer to the other leaflet. In eukaryotic cells, flippases are located in various organelles, including the endoplasmic reticulum (ER), where they flip-flop newly synthesized lipids. How membranes are made WebSolution The correct option is D While lipids can rarely flip - flop proteins cannot The lipids in the bilayer can sometimes undergo transverse diffusion or "flip-flop movement" to go from one layer to the other.
