NanoLuc™ (Nluc) is a 19.1 kDa, ATP- independent luciferase that utilizes a novel coelenterazine analog (furimazine) to produce high intensity, glow-type luminescence.
How is luciferase produced?
Luciferase assay. A scientist produces DNA constructs coding for a hypothetical transcriptional activator and a reporter sequence and introduces these constructs into cells in culture. If the protein is able to activate transcription, the cell will produce the luciferase reporter protein.
What is a luciferase expression?
A luciferase assay is used to determine if a protein can activate or repress the expression of a target gene. If the protein is able to upregulate transcription of the target gene, the cells will express luciferase. If the protein downregulates transcription, the cells will express less luciferase than normal.
How does Gaussia luciferase work?
Gaussia luciferase can be expressed in mammalian cells using commercially available reporter plasmids. This luciferase, which does not require ATP, catalyzes the oxidation of the substrate coelenterazine in a reaction that emits light (at 470 nm), and has considerable advantages over other reporter genes.
Is luciferase an activity?
The luciferase assay is useful to study whether a protein of interest regulates a particular gene at the transcription level. When this protein activates transcription, the cell will produce luciferase enzyme. After the addition of a lysis buffer and a substrate, a luminometer quantifies the luciferase activity.
When was luciferase first used?
While DuBois discovered the reaction between luciferin and luciferase in 1885, it was not until the late 1940s when the luciferase protein was first extracted and purified firefly lanterns by Drs. Green and McElroy. Using this process, they isolated the enzyme and determined its conformational structure.
Can luciferase be scanned?
The bioluminescence emitted can be detected and amplified using specialized cameras with highly sensitive detection systems [18], revealing the sites and levels of luciferase expression and activity from within a living animal.
Who invented luciferase?
Raphaël Dubois
The Discovery of Luciferin and Luciferase by Raphaël Dubois It was Raphaël Dubois’s work at the end of 19th century that validated his hypothesis.
Why was luciferase created?
Luciferase is a generic term for the class of oxidative enzymes that produce bioluminescence, and is usually distinguished from a photoprotein. The name was first used by Raphaël Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively….Luciferase.

Is luciferase toxic to cells?
The luciferase gene or luciferase bioluminescence activity does not affect the growth of cancer cell lines in vitro.
Can humans develop bioluminescence?
You Can’t See It, But Humans Actually Glow With Our Own Form of Bioluminescence. “The human body literally glimmers,” the team from the Tohoku Institute of Technology wrote in their study published in PLOS One. “The intensity of the light emitted by the body is 1,000 times lower than the sensitivity of our naked eyes.”
Why was it named luciferase?
The name was first used by Raphaël Dubois who invented the words luciferin and luciferase, for the substrate and enzyme, respectively. Both words are derived from the Latin word lucifer, meaning “lightbearer”, which in turn is derived from the Latin words for “light” (lux) and “to bring or carry” (ferre).
