Dye : APTS
9-Aminopyrene-1,4,6-trisulfonate (APTS) is dye that is frequently used for the analysis of mono or oligosaccharides. The labeling of sugars involves a reductive amination of the reductive function of the mono or oligosaccharides followed by reaction with the dye. APTS is routinely used in Capillary Electrophoresis separation. In this note, we analyze oligosaccharides labeled with APTS with a 480nm LED.
