The Luciferase Assay Reagent was specifically formulated to use with our (Luciferase Reporter) Cell Line products, which was designed to produce highly sensitive signal and prolonged signal intensity. As one-step glow assay reagent, the Luciferase Assay Reagent can be directly added to cell culture plates compatible with the luminometer being used without diluting or transferring culture supernatants or cell lysates to other plates.
