AAV with eSYN promoter driven EGFP

This AAV expresses EGFP 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.

EGFP is derived from the Aequorea GFP with a Excitation/Emission spectrum around 488nm/507nm. It is the most commonly used imaging probe. Other fluorescent proteins with similar emission spectrums are Emerald, and T-Sapphire
