Overview
D-luciferin is a common substrate for Luciferase and is widely used throughout biotechnology, especially in vivo imaging Technology. The mechanism of action is that luciferin (substrate) can be oxidized to emit light in the presence of ATP and luciferase. When fluorescein is in excess, the quantum number of light produced is equal to Luciferase concentrations were positively correlated (see figure below) . Plasmids carrying luciferase encoding gene (Luc) were transfected into cells and introduced into study animals such as rats and mice.
