Localization of proteins in cells detected with NanoLuc Luciferase

Sensitive, Bright Bioluminescent Imaging: No Excitation Required

Whole Animal Imaging

Bioluminescent imaging of cells and molecular processes in whole animals is important for studying normal physiology, monitoring disease progress or understanding response to therapy. The bright NanoLuc® reporter provides high sensitivity and low background when imaged in superficial mouse tissues and has also been used successfully to image events in deeper tissues. In addition, substrate specificity allows NanoLuc® and firefly luciferases to be used together for dual luciferase molecular imaging studies. Applications range from quantifying changes in tumor growth to visualizing viral replication and spread using engineered NanoLuc® reporter viruses.

Cell-based Imaging

Control of subcellular localization is an important mechanism for regulating the function and signaling activity of many proteins. For example, protein translocation from the cytosol to the nucleus or protein recruitment to the plasma membrane can be key events in signaling pathway activation. Bioluminescent imaging (BLI) can be used to monitor subcellular protein localization, allowing direct visualization of protein dynamics in living cells without the need for repeated sample excitation.

Monitoring translocation of a NanoLuc® Fusion Protein using Bioluminescence Imaging (BLI). HEK293 cells expressing a Protein Kinase C (PKC)-NanoLuc luciferase fusion protein were measured for 20 minutes following PMA treatment and application of furimazine substrate. BLI was performed on an Olympus LV200 Bioluminescence Imager.

The NanoLuc® reporter is well-suited for use as a protein tag in BLI studies. The extreme brightness means that exposure times can be reduced to only a few seconds compared to the minutes required for other luminescent reporter proteins. Also, the small size of NanoLuc® makes it less likely to perturb the normal biology or functionality of the fusion partner.

Step 1: Choose a Vector to Create NanoLuc® Fusion Protein

Choose a NanoLuc® Fusion Vector. We offer a range of vectors designed for simple generation of NanoLuc® luciferase N- or C-terminal fusion proteins with CMV-driven expression.
