Fluorescent Label
A fluorescent label is either a fluorescent molecule, or an enzyme system that generates a fluorescent product, which is linked to a ligand or binder tracer. The tracer is quantified by measuring the amount of light emitted by the tracer at a specific wavelength after exciting the tracer with incident light of a shorter wavelength. Fluorescent molecules include fluorescein and lanthanide chelates such as europium, samarium and terbium.
