AAV with EF1a promoter driven hChR2(C128S/D156A)-EYFP
This AAV expresses hChR2(C128S/D156A)-EYFP driven by an ubiquitous EF1a promoter.
The 1.2 Kb EF1α promoter is a commonly used, constitutive promoter derived from human elongation factor-1 alpha (EF1α). It is often used in conditions where the other constitutive promoters, such as CMV, have diminished activity or have been silenced.
hChR2 is a humanized version of ChR2 for mammalian expression. Wild-type ChR2, as well as a few of its mutations, provides the fastest excitation of the channelrhodopsins offered, and is widely used in in optogenetics techniques in neuroscience. hChR2(D156) mutant is another SFO mutation with a 6.9-minute open-state lifetime, and hChR2(C128S/D156A) double mutation creates a Stabilized Step Function Opsin (SSFO) with a stability of the active state up to 30 minutes.
Ready-to-use AAV expressing hChR2(C128S/D156A)-EYFP driven by an ubiquitous EF1a promoter. Available in AAV1, AAV2, AAV5, AAV6, AAV8, AAV9, AAV-DJ and other serotypes.
