Glycosylation is one of the most common post-translational modifications in biological system. Glycan play significant roles for a wide range of biological processes regulating such as cell-cell interactions, cell division and adhesion, cellular recognition, immune response, and protein stability. For the purpose of understanding the biological relevance of glycans, many mass spectrometry based methods have been developed for the relative quantitation of glycan. Herein, we describe a new in vivo labeling method either normal or heavy glucose to tag glycans from rice culture. Isotopic glucose enters the glucose metabolic pathway, which in turn produces nucleotide sugars precursors that are subsequently used for all glycan biosynthesis. Thus, each of sugars in glycan occur a mass shift as much as 1 Da. For glycan containing five sugars, occurs a mass shift of as much as 5 Da. A method for relative quantitation of glycans by ratio of normal glucose labeled glycan and heavy glucose labeled glycan.
