1) Luciferin, as the light-carrier substance or the energy-transfer substance, plays an indispensability role on the luminescent system of luciferase in the biology illuminant.

2) Now the known species of luciferin was variety, which had large differences on structure?property and synthesis. At present the research is focus on the biosynthesis of luciferin.

3) The first is known as a luciferin . This is the chemical that creates the light.

4) The mice were also regularly injected with luciferin, so that the luciferase would have the fuel it needed to glow.

5) The insects take in oxygen and, inside special cells, combine it with a substance called luciferin to produce light with almost no heat.

6) Light is emitted when luciferase is exposed to the appropriate luciferin substrate. Photon emission can be detected by light sensitive apparatus such as a luminometer or modified optical microscopes.
