Coelenterazine 400A is a derivative of coelenterazine and is a good substrate for Renilla reniformis luciferase (RLuc), but does not oxidize well with Gaussia (GLuc). It is the preferred substrate for BRET (Bioluminescence Resonance Energy Transfer) since its emission maximum of 400nm has minimal interference with the GFP emission.
Coelenterazine 400 a
MW: 391.48 g/mol
Purity: >95% by TLC
Color: Yellow to orange powder
Storage/Handling: Store at -20°C, and protect from light. Keep under inert gas.
Soluble in methanol or ethanol (NOT in DMSO).
Note: It is not recommended to store dissolved coelenterazine 400a at -20°C or -70°C. Coelenterazine 400a is a high energy dioxetanone ring structure that will spontaneously decompose even at low temperatures.
