D-Luciferin (potassium salt)

D-Luciferin is a chemiluminescent substrate of firefly luciferase. It produces light upon oxidative decarboxylation by luciferase in the presence of ATP. D-Luciferin can be employed to assay the expression of the luciferase gene linked to a promoter of interest. Alternatively, D-luciferin and luciferase can be used to assess ATP availability in cellular or biochemical assays.Formal Name: 4,5-dihydro-2-(6-hydroxy-2-benzothiazolyl)-4S-thiazolecarboxylic acid, monopotassium salt.
