Reporter Cell Lines

Reporter cell lines are stable cell lines that have been labeled with reporter genes, allowing the visualization and tracking of protein expression. The reporter gene is inserted next to the gene promoter of interest within a vector and transfected to a cell line. If the promoter is expressed in the cell line, the reporter gene will also be expressed, allowing monitoring of cellular metabolic processes, transcription factors, and protein localization. Common reporter genes include luciferase and fluorescent proteins like GFP and RFP. The origin of the cell line, intended application, and the reporter should be taken into consideration when selecting your product.
