WebMay 29, 2024 · Fluorescent probes or fluorophores (fluorescent dyes or proteins) are coupled to a secondary antibody or streptavidin to allow visualization of an analyte. Each fluorophore has its specific spectral characteristics, with excitation and emission spectra particular to the molecule. WebFluorescence labeling procedures convert nonluminescent or weakly luminescent molecules into highly fluorescent products. With the aid of specific probes, and in combination with appropriate detector systems, chemical and biochemical systems become amenable to fluorescence spectroscopy.
