Coelenterazine 400a

Coelenterazine 400a is a derivative of coelenterazine and is a good substrate forRenilla reniformisluciferase (RLuc), but does not oxidize well withGaussia (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.Product Specifications:Coelenterazine 400a2,8-Dibenzyl-6-phenyl-imidazo[1,2a]pyrazin-3- (7H) -oneDeepBlueCTMFormula: C26H21N3OMW: 391.48 g/molPurity: >95% by TLCColor: Yellow to orange powder
