AAV with CamKII promoter driven hChR2(E123T/H134R)-EYFP

This AAV expresses hChR2(E123T/H134R)-EYFP driven by a neuron CamKII promoter.

This 1.3 Kb promoter is derived from the murine α-Calcium/calmodulin-dependent kinase II (CaMKII), a gene with expression restricted to excitatory neurons in the neocortex and hippocampus. In cortical neurons, it was shown that the promoter activity of CaMKII(1.3) is about double that of CaMKII(2.4), probably due to some inhibitory element(s).

hChR2(E123T/H134R), also known as ChETA, is a channelrhodopsin-2 variant with faster deactivation kinetics.
