AAV with CAG2 promoter driven fLuc

This AAV expresses fLuc driven by an ubiquitous CAG2 promoter.

The CAG2 promoter is derived from the commonly used 1.8kb CAG/CBA (also called CAGGS) promoter. To increase the cloning capacity of size-limiting vectors using the CAG promoter, such as AAV or lentiviral vectors, CAG2 was developed by deleting a portion of about 0.6Kb of the chicken beta-actin intron from the original CAG promoter.

Firefly luciferase (fLuc) is an oxidative enzyme used in bioluminescence and is distinct from a photoprotein. In the luciferase reaction, light is emitted when luciferase acts on the appropriate luciferin substrate. Photon emission can be detected by a light-sensitive apparatus such as a luminometer or modified optical microscope. Firefly luciferase is commonly used as a reporter to assess the transcriptional activity in cells.
