This AAV expresses hChR2(C128S/D156A)-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 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.

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.
