AAV with ApoE/hAAT1 promoter driven roGFP1

This AAV expresses roGFP1 driven by a liver ApoE/hAAT1 promoter.

The ApoE/AAT1 chimeric promoter consists of the core promoter from human alpha-1-antitrypsin gene (also known as hAAT1, SERPINA1, A1A, A1AT, AAT, or alpha1AT) and the enhancer/hepatic locus control region (HCR) from the ApoE gene. The ApoE-hAAT1 chimeric promoter is about 0.7Kb and is used for driving gene expression in hepatocytes

roGFP1 is a reduction-oxidation sensitive green fluorescent protein used as a biosensor. Two cysteines were introduced into the beta-barrel structure of GFP; the oxidation state, reduced dithiol or the oxidized disulfide, of the engineered thiols determines the fluorescent properties of the sensor. roGFPs (roGFP1 and roGFP2), have two fluorescent excitation maxima at about 400 and 490 nm, respectively and display rapid and reversible ratiometric changes in fluorescence in response to changes in redox potential in vitro and in vivo.
