Fluorescent Dye

Fluorescent Dye

Fluorescent dye is a fluorescent chemical compound that can re-emit light upon light excitation. Fluorophores typically contain several combined aromatic groups, or planar or cyclic molecules with several π bonds. PEG spacers increase water solubility, enable efficient biolabeling in imaging and diagnostic R&D.
