AAV with CMV7 promoter driven hChR2(H134R)-TdTomato
This AAV expresses hChR2(H134R)-TdTomato 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.
Channelrhodopsins are light-gated ion channels that exist naturally in microalgae. hChR2 is a humanized version of ChR2 for mammalian expression. It is maximally excited by 470 nm light. 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. Due to delayed channel closure, hChR2(H134R) is a gain-of-function mutation that produces larger photocurrents than wild-type hChR2, but slows down channel kinetics.
