D-Luciferin Potassium Salt

D-luciferin is the natural substrate of the enzyme luciferase (Luc) which catalyzes the production of the typical yellow-green light of fireflies. The 560 nm chemiluminescence from this reaction peaks within seconds, with light output that is proportional to luciferase concentration when the substrate luciferin is present in excess. The luciferase (luc) gene is a popular reporter gene for research and agent screening. Chemiluminescent techniques are virtually background-free, making the luc reporter gene ideal for detecting low-level gene expression. In addition to its role as a reporter of gene expression, luciferase is commonly used in an extremely sensitive assay for ATP.
