AAV with hRPE(0.8) promoter driven SEAP
Cat. No: VB1215
Availability:
2-3 weeks
Name:
AAV-hRPE(0.8)-SEAP
This AAV expresses SEAP driven by a retina hRPE(0.8) promoter.
The RPE65 gene encodes a protein of the retinal pigment epithelium (RPE) with a key role in the cycling of retinoids. It was shown that a RPE promoter of about 0.8 Kb was sufficient to direct high RPE-specific expression in transgenic mice. The 1.5Kb version of the promoter hRPE(1.5), also gives RPE-specific expression, but the expression level is not as high as the 0.8Kb promoter. This is probably due to a negative regulatory element(s) present in the 1.5Kb promoter.
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.
