What is luciferase reporter?
What is luciferase reporter?
A commonly used reporter gene is the luciferase gene from the firefly Photinus pyralis. This gene encodes a 61-kDa enzyme that oxidizes D-luciferin in the presence of ATP, oxygen, and Mg(++), yielding a fluorescent product that can be quantified by measuring the released light.
What is luciferase assay used for?
A luciferase assay is used to determine if a protein can activate or repress the expression of a target gene.
Is firefly luciferase secreted?
Luciferase enzymes
Organism | Luciferase | Secreted |
---|---|---|
Photinus pyralis | North American firefly luciferase | No |
Luciola cruciate | Japanese firefly (Genji-botaru ) luciferase | No |
Luciola italic | Italian firefly luciferase | No |
Luciola lateralis | Japanese firefly (Heike) luciferase | No |
How does a reporter gene work?
Reporter genes are genes that enable the detection or measurement of gene expression. They can be fused to regulatory sequences or genes of interest to report expression location or levels.
How does a luciferase reporter assay work?
A Luciferase Reporter Assay. 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. If your protein activates the expression of the target gene, the amount of signal produced increases.
Which is a reporter gene for luciferase enzyme?
A commonly used reporter gene is the luciferase gene from the firefly Photinus pyralis. This gene encodes a 61-kDa enzyme that oxidizes D-luciferin in the presence of ATP, oxygen, and Mg(++), yielding a fluorescent product that can be quantified by measuring the released light.
How is Renilla luciferase used in a luciferase assay?
Next, the Renilla Luciferase Reagent is added to the same well. It quenches the firefly luciferase luminescence and provides the substrate for renilla luciferase to produce renilla luciferase luminescence. The light production of both reactions can be conveniently measured on a luminometer.
Why is firefly luciferase used as a sensitive reporter?
Firefly luciferase has been used as a sensitive reporter to study a wide range of biological responses. However the change of the expression of Firefly luciferase reporter can be due to a global effect instead of a specific effect.
Why are scientists interested in luciferin and luciferase?
Scientific interest in the chemistry of the luciferin-luciferase reaction didn’t stop there, as we know. Continued interest in the wondrousness of bioluminescent light has inspired researchers to explore the complexities more, and harness its power for biological breakthroughs .
