PFD-rAAV-EF1a-DIO-FLlnChR-mCherry-WPRE-hGHpA
The broad-spectrum promoter EF1a regulates the expression of Cre-dependent light repressive elements. FLlnChR-mCherry is expressed in the presence of Cre, but FLlnChR-mCherry is not expressed in the absence of Cre.

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 the CMV promoter is silenced, such as stem cells, 1178bp.
Functional Gene Details
FLlnChR: Excitation light wavelength 590nm.
Fluorescent Tag
mCherry
Fluorescent Protein Details
mCherry: red fluorescent protein, excitation wavelength 587nm, emission wavelength 610nm.
Virus Type
adeno-associated virus
Application
Expressing light-sensitive ion channel proteins, such as eNpHR3.0, Arch, etc., in neurons through rAAV viral vectors can specifically inhibit 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.
