Reporter Gene Assays

Reporter gene assays convert otherwise hard-to-observe transcriptional regulation and signaling pathway changes into quantifiable fluorescent or chemiluminescent signals. They are widely used in promoter function studies, pathway activity analyses, and drug screening. Reporter systems based on ...

Coelenterazine 400a is a chemically modified analog of native coelenterazine, designed to emit at shorter wavelengths (~395–400 nm) for high-sensitivity bioluminescent applications. This article explores its structural characteristics, origins, specific utility in BRET² and Ca²⁺ assays, ...
