Product Details
Promoter Details
CS-CRM4-aMHC, mouse cardiac alpha myosin heavy chain promoter (aMHC promoter adds CS-CRM4 enhancement region), 590bp, belongs to cardiac research promoter.
Functional Gene Details
hChR2(H134R): It is the most common form of ChR2. h refers to the coding sequence of the gene that has been optimized for the human codon table. H134R refers to the mutation of histidine at position 134 to arginine. This mutation inhibits the binding of H+ by ChR2 and increases the passing ability of Na+, thereby increasing the overall conductivity of the molecule and thereby increasing the inward current excited by light. Generally, blue light around 470nm is used for excitation.
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 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.
