Web1.2 Fluorescent dyes. Fluorescent dyes, also known as reactive dyes or fluorophores, have been used by biologists for decades. Fluorescent dyes offer higher photostability and brightness compared to fluorescent proteins and do not require a maturation time. However, fluorescent dyes are usually targeted to proteins of interest by antibody ... WebThe fluorescence output of a given dye depends on the efficiency with which it absorbs and emits photons, and its ability to undergo repeated excitation/emission cycles. Absorption and emission efficiencies are most usefully quantified in terms of the molar extinction coefficient (EC) for absorption and the quantum yield (QY) for fluorescence.
