The major protein in Chinese yam (<i>Dioscorea opposita</i> Thunb.) glycoprotein, 30CYGP, exhibits strong immunomodulatory activities. Research has identified the sequence and structure of 30CYGP; however, 30CYGP <i>N</i>-glycoform composition and immunoactivity remain unknown. We isolated and purified 30CYGP from Chinese yam and used that material to release the <i>N</i>-glycans contained within. The <i>N</i>-glycans were labeled with 1-phenyl-3-methyl-5-pyrazolone and analyzed via ESI-MS and o  ...[more]
