Weblikely to contribute to a better understanding of the mechanisms of photobleaching given the central importance of dye triplet states in photobleaching processes. The approach was applied to the measurement and characterization of the photobleaching of Rh6G in aqueous solution and FITC in 1 mM sodium carbonate buffer (pH 9). The WebFITC (Ex max 494 nm/Em max 520 nm) Fluorescein isothiocyanate (FITC) is a fluorochrome with a molecular weight of 389 Da. FITC is sensitive to pH changes and photobleaching. Due to nearly identical excitation and emission properties, FITC and Alexa Fluor® 488 cannot be used simultaneously. FITC is relatively dim and should be reserved for highly
