Coelenterazine (native form) is a luminescent enzyme substrate for apoaequorin and Renilla luciferase. The aequorin complex has been used as an excellent calcium indicator that can measure a broad concentration range of calcium from ~0.1 uM to >100 uM (References 1-4). Renilla luciferase, encoded by the luc gene, has been widely used as a reporter protein. Renilla luciferase/coelenterazine has also been used as the bioluminescence donor in bioluminescence resonance energy transfer (BRET) (5) to study protein-protein interactions. Other uses of coelenterazine include chemiluminescent detection of superoxide anion and peroxynitrite in cells or tissues (6-9). Biotium also offers Renilla Luciferase Assay Kits () and Firefly & Renilla Dual Luciferase Assay Kits (30005). See the coelenterazine flyer under downloads for a comparison of coelenterazine analogs.
