ATT 550 NHS ester is an amine-reactive dye for labeling various amine-containing molecules in the aqueous phase. To prepare labeling solutions, dissolve the reagent in anhydrous, amine-free DMF, or DMSO immediately before use.
ATT 550 is a yellow-fluorescent Rhodamine 6G and Rhodamine B-related dye with high fluorescence quantum yield, strong thermal and photostability, and excellent water solubility. ATT 550 is a cationic dye. After coupling to a substrate, the dye carries a net electrical charge of +1.
