Glycan Labeling Cleanup - S Cartridges
LudgerClean S cartridges are used for the purification of glycans after fluorescent labeling, including LudgerTag 2-AB (2-aminobenzamide) and 2-AA (2-aminobenzoic acid) labeling kits.
The procedure is very straightforward. The sample is loaded onto the cartridge's adsorption disc that has been primed with acetonitrile. The glycans adsorb onto the disc matrix while excess dye is removed by washing with an acetonitrile/water mix. The glycans are then desorbed by simply washing with water.
