Photobleaching fluorescence microscopy
WebNov 23, 2011 · FRAP (Fluorescence recovery after photobleaching) is used to characterize the mobility of cellular molecules. The experimental setup comprises a microscope, a light source and a fluorescent probe coupled to the molecule of interest. Several images using a low light level are acquired to determine the initial fluorescence, and then a high level ...

WebJan 15, 2014 · In fluorescence microscopy, photobleaching occurs when the excited electrons are trapped in a relatively long-lived triplet state. The forbidden triplet–singlet transition provides the fluorophore with a much longer time to undergo irreversible chemical reactions with the environment than does the singlet–singlet transition (Tsien et al., 2006 WebPhotobleaching correction in fluorescence microscopy images Nathalie B Vicente, Javier E Diaz Zamboni, Javier F Adur, Enrique V Paravani and Víctor H Casco Microscopy Laboratory, School of Engineering – Bioengineering, National University of Entre Ríos (UNER).
