Glycan staining or labeling. Because of their structure, glycan sugar moieties are not reactive to staining or labeling molecules. To overcome this problem, sugar groups can be chemically restructured with periodic acid, which oxidizes vicinal hydroxyls on sugars (especially sialic acid) to aldehydes or ketones that are then … See more Protein glycosylation has multiple functions in the cell.
