AAV with EF1a promoter driven hChR2(E123T)-mCitrine

This AAV expresses hChR2(E123T)-mCitrine 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(E123T) mutant accelerates the open state decay but reduces photocurrent amplitudes. Its maximal spectrum is near 495nM.
