Luciferase from Photinus pyralis (firefly) by Molecular Depot is a luciferase from the firefly Photinus pyralis, the enzyme responsible for firefly bioluminescence. It catalyses the oxidation of luciferin in the presence of oxygen, ATP and magnesium ions, and the reaction emits light. It is used in ATP determination, in bioluminescent assays and as a standard in luciferase reporter gene work. Each unit contains 500 µg. MBP supplies Molecular Depot enzyme reagents to research labs in the United States, Canada and worldwide.
