WebPropidium Iodide Nucleic Acid Stain 3 Fluorescence Spectral Characteristics When bound to nucleic acids, the fluorescence excitation maximum for PI is 535 nm and the emission maximum is 617 nm (Figure 1). PI can be excited with a xenon or mercury-arc lamp or with the 488 line of an argon-ion laser. Generally, PI fluorescence is detected in ... WebPhotobleaching (also termed fading) occurs when a fluorophore permanently loses the ability to fluoresce due to photon-induced chemical damage and covalent modification. Upon transition from an excited singlet state to the excited triplet state, fluorophores may interact with another molecule to produce irreversible covalent modifications.
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 modifications in covalent bonds are caused by transition from a singlet state to the triplet state of the fluorophores. The number of excitation cycles to achieve full bleaching var… WebFluorescence MicroscopeHigh-Intensity Light, Dyes and Stains.
