Furthermore, the secondary fluorescent antibody conjugates were selected for minimal spectral overlap. For computer-assisted analysis the brightfield microscopy image was combined with the fluorescence microscopy images. 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… biotin sigma-aldrich b4501-1g
