AAV with CMV-IVS promoter driven hChR2(H134R)-TdTomato
This AAV expresses hChR2(H134R)-TdTomato driven by an ubiquitous CMV-IVS promoter.
The CMV-IVS promoter is about 1.1 kb in length and consists of the commonly used CMV promoter/enhancer and the intron (IVS) from beta-globin . The presence of intron elements was shown to give a higher level of transgene expression than that of the original CMV promoter/enhancer.
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.
