COELENTERAZINE H Usage And Synthesis

Description

Coelenterazine-h (50909-86-9) may be used as a substrate in gene reporter assays, live cell assays, and biochemical assays (ELISA, BRET etc). Renilla luciferase catalyzes coelenterazine oxidation by oxygen to produce light. Coelenterazine-h produces 10-fold higher light output than native coelenterazine. Coelenterazine-h also undergoes autoluminescence, which is enhanced by superoxide anion and peroxynitrite in cells.

Uses

Coelenterazine h, is a derivative of Coelenterazine (C636000), and iis more sensitive to Ca2+ than is the native complex, thus providing a valuable tool for measuring small changes in Ca2+ concentrations.

Definition

ChEBI: Renilla luciferin is a member of phenols and an imidazopyrazine. It has a role as a luciferin. It derives from a hydride of an imidazo[1,2-a]pyrazine.

General Description

Coelenterazine is an imidazopyrazinone derivative. It is a substrate for bioluminescence in many luminous marine organisms.

Biochem/physiol Actions

10 times higher luminescence intensity than native coelenterazine.
