This product is an amine derivative of ROX (Rhodamine X, Rhodamine 101) dye with an amine group separated from the fluorophore by a long linker that facilitates conjugation. The aliphatic primary amine group can be coupled with various electrophiles (activated esters, epoxides, etc.) and used in enzymatic transamination labeling.
ROX is a red-emitting fluorophore possessing high brightness and fluorescence quantum yield. This reagent is a pure 6-isomer.
