WebPhotobleaching is the irreversible destruction of a fluorophore under the influence of light. FPbase catalogs efforts that have been made to quantify the photostability of various fluorescent proteins. Typically, these report the time that it takes for the emission intensity of a fluorescent protein to reach half of its initial value, or it may ...

WebSingle Fluorophore Photobleaching, Fig. 1. Jablonski diagram of a fluorophore, showing multiple pathways for photophysical and photochemical processes. Upon excitation, a fluorophore absorbs a photon and jumps to the excited singlet state ( 1 ), from which it can decay to ground state through radiative ( 2) or non-radiative ( 3) pathways. WebPhotobleaching. Photobleaching describes a decay of Fluorescence intensity caused by excitation light. It is typically caused by reactive oxygen species, which react with the … opti school freiburg
Minimizing Photobleaching in Fluorescence Microscopy
WebJun 20, 2008 · The spectroscopic and electrophoretic properties of proteins labeled with Chromeo P503 were investigated. Its photobleaching characteristics were determined by continually infusing Chromeo P503-labeled alpha-lactalbumin into a sheath-flow cuvette and monitored fluorescence as a function of laser pow … WebJun 1, 1995 · The photobleaching behavior of free and bound fluorescein has also been investigated by experimental means. Both the theoretical simulation and experimental data show that photobleaching of fluorescein in microscopy is, in general, not a single-exponential process. The simulation suggests that the non-single-exponential behavior is … In optics, photobleaching (sometimes termed fading) is the photochemical alteration of a dye or a fluorophore molecule such that it is permanently unable to fluoresce. This is caused by cleaving of covalent bonds or non-specific reactions between the fluorophore and surrounding molecules. Such irreversible … See more • Ozone depletion See more • Introduction to Optical Microscopy an article about photobleaching • Viegas MS; Martins TC; Seco F; do Carmo A (2007).
