Question

Quizplus · Accepted Answer

Ruthenium derivatives are commonly used in chemiluminescent assays as they emit light when oxidized in the presence of a suitable oxidant. This makes them a suitable label for such assays. Horseradish peroxidase is an enzyme that is often used in combination with other labels to generate luminescence. Iodine-125 is a radioactive isotope used in radioimmunoassay techniques. Fluorescein is a fluorescent dye that emits visible light when excited by ultraviolet radiation, but it is not typically used in chemiluminescent assays.
