Reporter gene assays have easily measurable phenotypes that form the basis of sensitive, quantitative and reproducible assays of eukaryotic gene expression and regulation. Specifically, researchers can use reporter genes to characterize the strength of promoters and enhancers, define the role of transcription factors, assess transfection efficiency or the like. Fluorescent proteins are the most common fluorescent probes for imaging-based reporter gene assays.
