Xylose, a monosaccharide typically found in plants and insects but not mammalian or yeast expression vectors, can be used as an internal standard (i.e. added to each sample before labelling). This allows compensation for any pipetting/sample preparation errors that may have occurred during sample processing.
As well, xylose assists in determining whether high salt labeling inhibition is occurring. High salt may inhibit glycan labeling
