Chemical Structure
Product Description
D-Luciferin is a firefly luciferase substrate. Its quantum efficiency is 0.88, which is 20 times that of Luminol. The reaction mechanism is shown below. First, Luciferin reacts with ATP by luciferase in the presence of magnesium ion, then it is oxidized to form dioxetane structure and emits yellow-green light. Luciferin-luciferase luminescence is used for ATP monitoring to determine cell viability and bacteria counting. It is also used for reporter gene assays.
