Promega Corporation

Promega Corporation is a privately held life science company headquartered in Madison, Wisconsin, that has been supplying researchers with molecular biology reagents since 1978. The company is best known for its bioluminescence-based assay technologies, particularly the luciferase reporter systems that underpin countless gene expression, cell viability, and drug metabolism studies. CellTiter-Glo luminescent cell viability assays are among the most widely cited reagent brands in pharmaceutical drug discovery. Promega's NanoLuc luciferase, a small and exceptionally bright reporter derived from deep-sea shrimp, has become a transformative tool for live-cell imaging and split-reporter complementation assays. Their Maxwell automated nucleic acid extraction instruments and reagents offer streamlined workflows for DNA and RNA purification from diverse sample types. Promega supplies a comprehensive range of PCR and RT-PCR reagents, cloning systems, in vitro transcription kits, and protein expression tools including the popular TNT Coupled Transcription/Translation Systems. Forensic DNA analysis labs rely on Promega's STR typing kits, which are validated for use in national DNA databases. The company also provides a broad portfolio of restriction enzymes, ligases, and nucleotide products, and their GoTaq DNA polymerase family is a staple in academic teaching and research labs globally.
