PFD-rAAV-EF1α-DIO-C1V1-EYFP-WPRE-hGH polyA
For a hybrid composed of ChR1 and VChR1 (a mutant of ChR), the C1V1 photocurrent decay rate is more than 10 times slower than that of ChR2 and slower than that of VChR1.

Product Details
Promoter Details
Ef1α, strong promoter, human targeted elongation factor 1α (EF1A) gene, can be stably expressed in most types of cells, especially cells where some CMV promoters are silenced, such as stem cells, 1178bp.
Functional Gene Details
C1V1: It is a new ion channel formed by the fusion of ChR1 and VChR1 fragments. This protein is very sensitive. C1V1 expressed in C. elegans can work under 0.2-0.5mW/mm2 light. The maximum absorption wavelength is 540-580nm. It can also be activated by 400nm laser. The common C1V1 carries two point mutations, E122T and E162T, to improve activity, so it is also called C1V1(t/t). The excitation light wavelength is 560nm.
Fluorescent Tag
EYFP
Fluorescent Protein Details
EYFP: Yellow fluorescent protein, excitation wavelength 513nm, emission wavelength 527nm.
Application
Expressing light-sensitive ion channel proteins, such as ChR2, ChrimsonR, etc., in neurons through rAAV viral vectors can specifically excite neurons and explore the effects of light stimulation on neurons, neural circuits and animal behavior.
Regulatory Element Details
DIO: Double-floxed inverse Orientation, is an element that cooperates with Cre recombinase to control the expression of the target gene. If there is no Cre recombinase, the target gene will not be expressed, but in the presence of Cre, the target gene can be expressed normally.
Notes
1. Short-term storage at 4°C; long-term storage at -80°C
2. It can be stored at -80°C for more than 6 months. Each time it is frozen and thawed, the titer will be reduced by 10%, and repeated freezing and thawing should be avoided; if the virus is stored for more than 6 months, it is recommended to re-measure the virus titer before use
3. According to the experimental needs, the virus can be appropriately diluted and divided into the volume required for each experiment.
Expression and Regulation Mode
Cre-dependent
