lu·cif·er·in

 (lo͞o-sĭf′ər-ĭn)
n.
A chemical substance present in the cells of bioluminescent organisms, such as fireflies, that produces an almost heatless, bluish-green light when oxidized under the catalytic effects of luciferase and ATP.

[Latin lūcifer, light-bringing; see Lucifer + -in.]

luciferin

(luːˈsɪfərɪn)
n
(Biochemistry) biochem a substance occurring in bioluminescent organisms, such as glow-worms and fireflies. It undergoes an enzyme-catalysed oxidation and emits light on decaying to its ground state
[C20: from Latin lucifer (literally: light-bearer) + -in]

lu•cif•er•in

(luˈsɪf ər ɪn)

n.
a pigment of bioluminescent organisms that emits light while being oxidized.

A few of these substances include luminol and luciferin. High-sensitivity luminometers are devices that are used to measure such high-sensitivity light emitted in luminescent reactions.
The tiny organisms produce light using a chemical called luciferin as a defence mechanism to draw predators towards the creature trying to eat the plankton.
The light is the result of bioluminescence, a chemical reaction between luciferin and luciferase when exposed to oxygen, which the firefly regulates into its abdomen.
In the lantern, the chemical compound luciferin and the enzyme luciferase react with oxygen to produce light, which is directed and intensified by reflectors.

FACT FILE BIOLUMINESCENT plankton are tiny organisms which produce light using a chemical called luciferin.
The bioluminescence occurs in the organisms when a pigment called luciferin undergoes a chemical reaction, often triggered by an enzyme which emits light.
Luciferase reacts with a molecule called luciferin, causing it to emit light in the presence of adenosine triphosphate (ATP), the fuel derived from sugar.
Of the available systems, the most commonly used is the luciferase from firefly (Photinus pyralis) [4] in combination with the substrate luciferin.
For the acquisition of BLI, the mice were placed individually in the specimen chamber of the IVIS system and the light intensity at 10 min after luciferin administration was measured for 1 min.
They also used two other components called luciferin and coenzyme A.
