AAV with MBP promoter driven hChR2(E123T)-mCitrine

This AAV expresses hChR2(E123T)-mCitrine driven by an olgiodendricyte MBP promoter.

The myelin basic proteins (MBPs) are a family of polypeptides that are predominantly expressed in the nervous system, where they play a major role in myelination. This 1.3 Kb MBP promoter drives reporter gene expression mainly in oligodendrocytes.

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.
