This AAV expresses hChR2(E123A)-mCitrine driven by a neuron CamKII(0.4) promoter.

This 0.4 Kb promoter is derived from murine α-Calcium/calmodulin-dependent kinase II (CaMKII), a gene with expression restricted to excitatory neurons in the neocortex and hippocampus. It was shown that the promoter activity of CaMKII(0.4) is almost identical to that of CaMKII(1.3) in cortical neurons, Compared to CaMKII(1.3), this short promoter allows cloning of longer gene of interest into the AAV construct .

Channelrhodopsins are light-gated ion channels that exist naturally in microalgae. 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(E123A) mutant accelerates the open state decay but reduces photocurrent amplitudes. Its maximal spectrum is near 485nM.

About Storage Conditions

All our viral products should be kept at -80°C. At this temperature, the virus will remain stable for 6-12 months (and in some cases, up to 2 years). Once thawed, the product can be stored at 4°C for 2-3 weeks without significant loss of biological activity. We recommend aliquoting your vectors into low protein binding tubes upon receipt. This helps avoid repeated freeze-thaw cycles, as well as prevent loss of virus. To maintain accurate titer, aliquot in at least 20ul per tube.
