Schematic illustration of a FLIP experiment, for a cell containing green fluorescent molecules. (a) The cell at steady sate. (b–f) A small region is repeatedly bleached by laser light (orange flash). Fluorescence begins to fall in the cytoplasm and in some organelles (ellipses). This demonstrates diffusive transport of molecules towards the bleached region with recruitment from some of the organelles.
