6-Carboxy-X-rhodamin-N-succinimidylester / 6-ROX-SE

Amine-reactive carboxy-X-rhodamine dye marker for fluorescence labeling, especially for labeling of biomolecules (Abs: 584 nm, Em: 599 nm).

The amine-reactive derivative of carboxy-X-rhodamine has a long-wave fluorescence emission and is widely used as a fluorescent label for convenient covalent labeling of proteins and alkylaminomodified nucleic acids.
