The 8-Aminopyrene-1,3,6-trisulfonic acid trisodium salt is a very useful green fluorescent dye for labeling glycoproteins or sugar molecules in general. The labeling occurs via reductive amination which involves the formation of a Schiff base between the amine of 8-Aminopyrene-1,3,6-trisulfonic acid trisodium salt and the aldehyde or ketone of the sugar, followed by the reduction of the Schiff base linkage to a stable carbon-nitrogen bond. The multi-anionic nature of the dye makes it ideal for the studies of carbohydrate molecules by high resolution capillary electrophoresis.

The 8-Aminopyrene-1,3,6-trisulfonic acid trisodium salt is irritating to eyes, respiratory system and skin. Do not breathe dust. Avoid contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If you want to contact the product, you must wear suitable protective clothing.
