AAV with eSYN promoter driven fLuc

This AAV expresses fLuc driven by a neuron eSYN promoter.

The eSYN is a hybrid promoter consisting of a 0.4Kb CMV enhancer (E) and the 0.45Kb human Synapsin I promoter fragment (hSYN1). eSYN hybrid promoter gives about 2-4 fold higher expression than that of the parental hSYN1 promoter. However, the neuronal specificity of eSYN is slightly decreased, compared to that of the parental hSYN1 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.
