ROX alkyne is an alkyne derivative of the bright red-emitting dye ROX (Rhodamine X, Rhodamine 101). Due to its quantum yield approaching unity, ROX is a popular dye for qPCR and microscopy applications. It is used for fluorescent labeling of azide-containing biomolecules via copper-catalyzed click reaction. This product is a pure 5-isomer of ROX.
ROX is prone to oxidation; therefore, its derivatives should preferably be stored in an inert atmosphere.
