Fluorescent Dyes, or fluorophores, Fluorescent Probes & Stains, are compounds that absorb light at a given wavelength and emit light at a higher wavelength, producing fluorescence. These fluorescent dyes can be grouped into categories, such as organic dyes (e.g., fluorescein, rhodamine, AMCA), biological fluorophores (e.g., green fluorescent protein, phycoerythrin, allophycocyanin), and quantum dots. They are often used in the fluorescent labeling of biomolecules. They are smaller and more photostable than fluorescent proteins.
Fluorophores are safe to use and do not require radiological controls. Several fluorophores can be used simultaneously when they don’t overlap.
