EF1a-hM3Dq-mCherry AAV (Serotype 9)

EF1a-hM3Dq-mCherry AAV (serotype 9) is a powerful tool for neuroscience research. Adeno-associated virus (AAV) vectors are a popular choice for gene delivery due to their relatively low immunogenicity and ability to transduce a wide range of cell types. Serotype 9 is particularly known for its efficient transduction in neural tissue, making it an ideal vector for applications targeting the central nervous system.

This specific AAV vector is genetically engineered to express hM3Dq, a designer receptor activated only by designer drugs (DREADDs), fused to the mCherry fluorescent protein. The hM3Dq receptor belongs to a class of genetically engineered muscarinic receptors that can modulate neuronal activity when activated by otherwise inert compounds such as clozapine-N-oxide (CNO). This chemical genetics approach allows researchers to selectively control neuronal circuits in vivo with spatial and temporal precision, offering significant advantages over traditional methods. The mCherry fluorophore, fused to hM3Dq, serves a dual purpose: it enables easy visualization and tracking of receptor expression in living or fixed tissues, and it helps verify successful transduction and expression of the target gene.
