Luciferin is a common bioluminescent substrate used for imaging and quantification of luciferase expression. It emits a characteristic yellow-green light upon oxidation by luciferase in the presence of cofactors such as ATP, Mg2+ and oxygen.

Luciferin is a common reagent used in the biotechnology field and specifically for in vivo imaging. Luciferase labeled tumor cells, stem cells or infectious diseases are typically injected into research animals such as rats or mice. The injection of luciferin allows for the real-time, noninvasive monitoring of disease progression and/or drug efficacy in these model systems using bioluminescent imaging instruments.

Luciferin is also commonly used for in vitro research, including luciferase and ATP assays, gene reporter assays, high throughput sequencing and various contamination assays.
