Fluorescent microscope bleached staining
Web16) A microscope is equipped with a laser that can be focused on a small region of the cell. The laser beam is used to bleach fluorescent tubulin in a small region of the cell. The specimen is then followed over time and the recovery of the fluorescent signal into the bleached zone is then measured. What is the name of this technique? WebFluorescence recovery after photobleaching (FRAP) is a method for determining the kinetics of diffusion through tissue or cells. It is capable of quantifying the two-dimensional lateral diffusion of a molecularly thin film containing fluorescently labeled probes, or to examine single cells.
