Reporter gene vectors and assays

Gene reporter systems play a key role in gene expression and regulation studies. This review describes the ideal reporter systems, including reporter expression vector design. It summarizes the many uses of genetic reporters and outlines the currently available and commonly used reporter systems. Each system is described in terms of the reporter gene, the protein it encodes, and the assays available for detecting presence of the reporter. In addition, each reporter system is analyzed in terms of its recommended uses, advantages, and limitations.
