product name Coelenterazine
Description: Coelenterazine is a luminescent enzyme substrate, used for monitoring reporter genes in BRET, ELISA and HTS techniques. It is a cell-permeable aequorin luminophore that acts as a very sensitive and specific chemiluminescent probe for the superoxide anion. Coelenterazine can also be used for detecting changes in intracellular Ca2+ in cells that have been transfected with apoaequorin cDNA. Coelenterazine also acts as a powerful antioxidant.

In vitro activity: When monitoring various biological processes, coelenterazine (CTZ) can be catalyzed by luciferases, such as the sea pansy Renilla reniformis (Rluc) and the marine copepod Gaussia princeps (Gluc), which results in emission of blue light. In Gli36-Gluc- or Gli36-Rluc-expressing Gli36 cells, coelenterazine shows a bioluminescence signal. In RIN-5F, 4T1, HCT 116, HEK 293, 293FT, HeLa and INS-1 cells, coelenterazine can be used to assay superoxide anion concentrations Kinase Assay: Cell Assay: Coelenterazine showed antioxidative properties in primary cultures of rat hepatocytes subjected to the oxidant tert-butyl hydroperoxide (t-BHP). Coelenterazine (3-10 μM) concentration-dependently increased survival and decreased lipid peroxidation in rat hepatocytes treated for 6 hr with t-BHP (250 μM) [2]. In addition, Coelenterazine (10 μmol/l) can be used to assay superoxide anion concentrations in cancer cell lines. |

| In Vivo | the small molecule coelenterazine (5 mg/kg, intravenous administration) was a potential reporter of cancer-associated superoxide anion in the 4T1 breast adenocarcinoma mouse model [1]. Gli36-Rluc or Gli36-Gluc cells were injected into the leg muscle of nude mice. The mice were injected with 4 mg/kg of coelenterazine and imaged by a cooled charge-coupled device camera. |
| Animal model | 5 mg/kg, intravenous administration |
