AAV with ApoE/hAAT1 promoter driven SEAP

This AAV expresses SEAP 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

The SEAP reporter gene encodes a truncated form of the human placental alkaline phosphatase that lacks the membrane anchoring domain. Therefore, the protein can be efficiently secreted from transfected cells allowing for detection of reporter gene activity without cell lysis. Using a secreted reporter protein has several advantages over traditional reporter assays: 1) Cell lysis is not required for analysis so a single set of cells can be used for both the SEAP assay and another purpose; 2) Gene expression kinetics can be studied by the repeated collection of the culture medium from the same cultures; and 3) By changing the culture medium prior to an experiment, the assay background is reduced to an extremely low level.
