Chemical Properties
Yellow Solid
Uses
Coelenterazine, native was used:-
- For Aequorin assays
- For measuring the intracellular calcium concentration in response to ionomycin or PMA using aequorin in COS-7 cells
- In Bioluminescence imaging for analysing the presence of virus-dependent luciferase activity
Uses
Coelenterazine is a luminophore of the aequorin complex which is oxidized by oxygen to illuminate at 465nm when Ca2+ binds to the complex. Used to measure Ca2+ concentration in cells with high sensitivity an dlarge dynamic range.
Definition
ChEBI: An imidazopyrazine that is imidazo[1,2-a]pyrazin-3(7H)-one in which positions 2, 6, and 8 are substituted by 4-hydroxybenzyl, 4-hydroxyphenyl, and benzyl groups, respectively.
General Description
Coelenterazine is a luciferin molecule, which is utilized by several luciferases, such as
Renilla,?
Oplophorus and?
Periphylla.
