Overview

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.
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.
