General description
Contents: Lyophilizate
Specific activity: Approximately 15 mU/mg protein at +25°C with FMN and myristine aldehyde as the substrates, and 50 mU NAD(P)H:FMN oxidoreductase per ml assay solution (based on the relative light emission in the ATP system under the formation of pyrophosphate with 1 mU luciferase from Photinus pyralis).
Alkanal reduced FMN-oxygen oxidoreductase (1-hydroxylating, luminescing)
Luciferase from bacteria exists as a heterodimer with α and β chains.
Application
Luciferase may be used:
- to treat mammary tumor cryosections for bioluminescence imaging studies
- as a component of luciferase reaction mixture
- in bioluminescence assay membrane preparations of Zymomonas mobilis
Biochem/physiol Actions
Luciferase catalyzes the conversion of reduced flavin mononucleotide in the presence of oxygen and long-chain aldehyde to flavin mononucleotide, visible light and a fatty acid. It is a reporter enzyme for sensitive quantitation. The lucifearse fusion proteins have been useful in many protein based interaction studies especially in living cells.
Preparation Note
Store at 2 to 8 °C. (A decrease in activity of approximately 20% may occur within 12 months.)
Analysis Note
Contaminants: <10 mU NADH:FMN oxidoreductase/mg protein, <10 mU myokinase/mg protein, and <1 mU NADH oxidase/mg protein
Other Notes
For life science research only. Not for use in diagnostic procedures.

Synthesis of bacterial luciferase in some strains of luminous bacteria requires a threshold concentration of an autoinducer synthesized by the bacteria and excreted into the medium. Autoinducer excreted by Photobacterium fischeri strain MJ-1 was isolated from the cell-free medium by

It has been shown that oxygen gradients exist in R3230AC tumors grown in window chambers. The fascial surface is better oxygenated than the tumor surface. The purpose of the present study was to determine whether gradients exist for energy metabolites

Glutamate is generated during nutrient stimulation of pancreatic islets and has been proposed to act both as an intra- and extra-cellular messenger molecule. We demonstrate that glutamate is not co-secreted with the hormones from intact islets or purified α- and
