Reporter Genes

Reporter genes are genes that are used to measure gene expression levels, usually during a scientific experiment. These genes typically encode proteins or enzymes that interact with a substrate to produce a visible signal or reaction, such as light, fluorescence, or color change. The expression of these genes, or the presence of the visible signal, enables scientists to quickly and accurately measure the activity of a gene of interest. Reporter genes are important tools in both basic research and biotechnology, allowing scientists to gain insight into gene function, disease development, and drug discovery.
