Coelenteramine 400a  (Synonyms: Coelenterazine 400a; Bisdeoxycoelenterazine)

Coelenteramine 400a (Coelenterazine 400a), a derivative of Coelenterazine, is a Renilla luciferase (RLuc) substrate. In the presence of Coelenteramine 400a, RLuc can emit blue light at 395 nm^[1][2]. Coelenterazine 400a will causes color change in the bioluminescence reaction of Rluc by replacing the sulfur and oxygen heteroatoms of the methylene bridge. Coelenterazine 400a provides higher signal resolution and can be used in the research of bioluminescence resonance energy transfer (BRET)^[3].
