This AAV expresses C1V1(E122T)-TS-TdTomato driven by an ubiquitous CAG2 promoter.

The CAG2 promoter is derived from the commonly used 1.8kb CAG/CBA (also called CAGGS) promoter. To increase the cloning capacity of size-limiting vectors using the CAG promoter, such as AAV or lentiviral vectors, CAG2 was developed by deleting a portion of about 0.6Kb of the chicken beta-actin intron from the original CAG promoter.

C1V1 is a chimeric channelrhodopsin made to boost membrane expression higher than VChR1 but with a different light spectrum. It is composed of ChR1 and VChR1 fragments, and implements fast, potent optical excitation at red-shifted wavelengths. C1V1(E122T) mutant has moderate off-kinetic with 130ms, and is red-shifted to 550nm, compared to C1V1.

The trafficking signal (KSRITSEGEYIPLDQIDINV) is also from the inward rectifier potassium channel Kir2.1; it serves to dramatically reduce intracellular accumulation and improve membrane targeting, leading to a profound increase of photocurrents. This is the basis for many third-generation optogenetics tools.

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.
