ATT 633 NHS ester is an activated ester of the ATT 633 fluorophore, designed for covalent labeling of biomolecules containing primary amine groups. The reagent efficiently reacts with ε-amino groups of lysine residues and N-terminal amino groups of proteins, forming stable amide bonds.

ATT 633 is a far-red hydrophilic dye characterized by high molar absorptivity and quantum yield. The fluorophore exhibits good photostability, provides a bright signal and high detection sensitivity, and is suitable for a wide range of applications, including fluorescence microscopy, flow cytometry, and in-gel visualization.
