rAAV-hSyn-ChrimsonR-EGFP-WPRE-hGH polyA
Mature neuron-specific promoter hSyn regulates the expression of light-activated elements This AAV expresses ChrimsonR-EGFP driven by a neuron hSyn promoter. hSyn is a Human synapsin 1 gene promoter. ChrimosonR is a new type of light-controlled ion channel that can respond to red light around 600nm. On the basis of Chrimson (CnChR1), the point mutation of K176R is made, which speeds up the speed of channel closing, so that at least it can effectively respond to optical signals of 20Hz and below. When used with Chronos, it is possible to control two different neurons with two kinds of fluorescence.

Product Details
Promoter Details
hSyn, human synapsin promoter, mature neuron-specific promoter, 448bp.
The h S yn promoter, also known as the h S yn 1 promoter, is cloned from the promoter region of human synapsin protein 1 (S ynapsin 1). It is about 0.5kb in length and is specifically expressed in neurons.
Functional Gene Details
ChrimsonR: A new type of light-controlled ion channel that can respond to red light around 600nm was discovered through high-throughput sequencing in the Boyden laboratory. A point mutation of K176R was made on the basis of Chrimson (CnChR1), which speeds up the channel closing speed, making it possible to effectively respond to light signals at least 20Hz and below. When used with Chronos, it is possible to control two different neurons with two fluorophores. The excitation light wavelength is 590nm.
Fluorescent Tag
EGFP
green fluorescent green
Fluorescent Protein Details
EGFP: green fluorescent protein, excitation wavelength 488nm, emission wavelength 507nm
EGFP: Green fluorescent protein, excitation wavelength 488nm, emission wavelength 507nm.
Virus Type
adeno-associated virus
Adeno-associated virus vector Adeno-associated Virus
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.
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.
