Description

Minimal promoter

The proximal promoters are shorter than 500 bp and contain transcription factor binding sites. Upon stimulation in 293 cells, their expression level remains undetectable. With the addition of repeated TFBS, the proximal promoters become inducible by the appropriate stimulus and drive the expression of the reporter gene.

mIFNβ promoter: The mouse interferon beta minimal promoter comprises several positive regulatory domains (PRDs) that bind different cooperating transcription factors such as NF-κB, IRF3 and IRF7 [1]. Co-expression of IFNβ-SEAP with constitutively activated IRF3 (saIRF3) or IRF7 (saIRF7) in HEK293 cells led to a strong increase in SEAP expression.

Reporter Gene

SEAP reporter gene: Secreted alkaline phosphatase (SEAP) is a reporter widely used to study promoter activity or gene expression. SEAP expression can be rapidly and readily measured in supernatants of transfected cells. SEAP levels can be evaluated qualitatively with the naked eye and quantitatively using SEAP detection media, such as HEK-Blue™ Detection system or the SEAP Reporter Assay.
