Methods for preparing labeled glycosylamines from a complex matrix are provided. The methodology includes the steps of: denaturing glycoproteins in a complex matrix to form a denatured complex matrix mixture; loading the denatured complex matrix mixture onto a MWCO filtration device; adding a glycosidase enzymatic solution onto the MWCO filtration device to form a deglycosylated complex matrix mixture comprising glycosylamines; collecting glycosylamines released from the MWCO filtration device; and derivatizing glycosylamines with a rapid tagging reagent to form a plurality of labeled glycosylamines suitable for detection in various liquid chromatography systems and detectors.
Methods for the rapid preparation of labeled glycosylamines and for the analysis of glycosylated biomolecules producing the same

Methods of analyzing glycosylated biomolecules include the steps of producing a deglycosylation mixture of biomolecules deglycosylated by natural or synthetic enzymatic or chemical techniques; providing a reagent solution having a labeling reagent in a polar aprotic, non-nucleophilic organic solvent; and mixing the deglycosylation mixture with the reagent solution in an excess of labeling reagent to produce derivatized glycosylamines. The method steps can be carried out purposefully without depletion of protein matter. A quenching solution can be added to the reaction mixture so that the pH of the reaction mixture is shifted to above 10. The yield of derivatized glycosylamines can be in an amount of about 80 to about 100 mole percent of the reaction mixture with minimal overlabeling, less than 0.2 mole percent. The derivizated glycosylamines can be separated from the reaction mixture and detected by chromatographic detection, fluorescence detection, mass spectrometry (“MS”), or Ultra Violet (“UV”) detection and/or a combination thereof.
