NanoLuc Luciferase

This part contains the protein coding region for the NanoLuc(tm) luciferase, which is originally designed by Promega Corporation (http://bit.ly/1Vgmab3, free for research use). Nanoluciferase is a small and monomeric enzyme (19.1kDa) and is about 150 times brighter than other luciferases. The new substrate called furimazine produces a high intensity luminescence.

After looking at the bibliography, Nanoluciferase gene was chosen because it allowed us to have a stronger signal. Indeed, this protein isn’t secreted but unfused. Furthermore, its intracellular half-life is superior to 6 hours and the Nanoluciferase has a low autoluminescence. This gives us maximum sensitivity. NLuc is used in biomedical research for several applications, including studying protein-protein interactions, monitoring protein stability, BRET-based sensors, molecular imaging or investigating genetic regulation and cell signaling. The emission pic of nanoluciferase is located at 460nm. We codon-optimized the part for yeast. The NanoLuc is smaller than other luciferases while yielding equal or stronger luminescence readings.
