Fluorescent dye labelling using purines

WebThe principle behind fluorescence is that the fluorescent moiety contains electrons which can absorb a photon and briefly enter an excited state before either dispersing the energy non-radiatively or emitting it as a photon, but with a lower energy, i.e., at a longer wavelength (wavelength and energy are inversely proportional). The difference in the … 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.
