1. A glycosylamines labeling kit, said kit comprising,
(a) an aldehyde selected from the group consisting of DL-glyceraldehyde, glyceraldehyde dimer, glycoaldehyde dimer, erythrose, pyruvaldehyde, 2-ethylbutyraldehyde, 2-methylbutyraldehyde, 2-methylvaleraldehyde, 4-methyl-4-nitrovaleraldehyde, acetaldehyde, butyraldehyde, isobutyraldehyde, propionaldehyde, or valeraldehyde,
(b) an amine-reactive dye capable of covalently binding to a free amino or amine end group of a glycoprotein or a glycopeptide under conditions allowing said amine reactive dye to covalently bind to said free amino or amine end group of said glycoprotein or said glycopeptide, and
(c) instructions on denaturing a glycoprotein or glycopeptide in the presence of said aldehyde.
