Would anybody know a good AAV serotype and promoter that would preferentially infect progenitor neuronal cells in the dentate gyrus, DCX+ cells that could be imaged after 7-9 days after infection?
I have tried AAV8-CMV- labeled internecine only, and AAV9-eIF2alpha, didn't label progenitors but had labeled mature granule cells. I cannot not use retroviruses.
