Coelenterazine 400a, also called DeepBlueC&#x2122;, is a coelenterazine derivative that serves as a substrate for <i>Renilla luciferase</i> (Rluc) and generates an emission peak centered around 400 nm. It is the preferred Rluc substrate for BRET studies because it has minimal interference with the emission of the GFP acceptor. <ul> <li>Yellow solid soluble in MeOH or EtOH</li> <li>Store at 20&deg;C and protect from light</li> <li>C₂₆H₂₁N₃O</li> <li>MW: 391.46</li></ul>DeepBlueC is a trademark of BioSignal Packard.
