Brite-Light™ D-Luciferin, Potassium Salt

Luciferin is a substrate for luciferase. It is oxidised by luciferase to generate light in the presence of ATP. Luciferase is used as a reporter gene linked to a promoter of interest. Luciferin is used to assess the expression of the luciferase gene. It is also used to assess ATP availability in cellular or biochemical assays.
