AAV with CMV7 promoter driven hChR2(T159C)-Venus

This AAV expresses hChR2(T159C)-Venus driven by an ubiquitous CMV7 promoter.

The CMV7 promoter is about 0.35 kb in length and is a shortened version of the commonly used CMV promoter. CMV7 has a truncated version of the CMV enhancer. When tested in several cell lines, this promoter provides an expression level that is about 3-5 fold lower than that of the original 0.6Kb CMV promoter.

hChR2 is a humanized version of ChR2 for mammalian expression. The wild-type, as well as a few mutations, provide the fastest excitation of the channelrhodopsins offered, and are widely used in optogenetics techniques in neuroscience. hChR2(T159C) shows slightly higher photocurrents than the hChR2(H134R), another commonly used optogenetics tool.
