The ViviRen™ and EnduRen™ Live Cell Substrates have been developed to make measuring Renilla luciferase from live cells simpler and more sensitive than was possible with the substrates coelenterazine and coelenterazine-h. ViviRen™ Substrate generates very bright luminescence, at least 3-fold brighter than coelenterazine, while EnduRen™ Substrate generates very stable luminescence, permitting multiple measurements over incubations of 24 hours or more. Both live cell substrates can be multiplexed with CellTiter-Glo® Reagent to normalize for viable cell numbers. Alternatively, the Chroma-Luc™ red Luciferase can be used to normalize for viable cell number or transfection efficiency.
