AAV with GFAP(2.2) promoter driven mCitrine

This AAV expresses mCitrine driven by an astrocyte GFAP(2.2) promoter.

The GFAP(2.2) promoter is based on human glial fibrillary acidic protein gene (GFAP), which is the major intermediate filament protein in astrocytes. It has been shown that approximately 2 kb of 5'-flanking DNA of the human GFAP gene is sufficient to direct transgene expression to astrocytes and confer developmental/injury-induced regulation.

mCitrine, like Venus, is derived from YFP, with increased brightness and stability. mCitrine has an Excitation/Emission spectrum of 516nm/529nm which is almost identical to that of EYFP, Venus and Topaz.
