ROX (Rhodamine X, Rhodamine 101) is a red-emitting fluorophore possessing high brightness and fluorescence quantum yield. This reagent is a pure 6-isomer.
ROX carboxylic acid is a non-reactive form of ROX dye that can be used as a reference standard in experiments involving ROX dye conjugates. Besides, the carboxylic group can react with hydrazines, hydroxylamines, and amines using carbodiimides such as EDAC.
