Glycan Profiling and Identification

We offer UPLC-FLD/MS of 2-AB, 2-AA or procainamide labeled glycans profiling service of cell, tissue or glycoprotein samples, and MALDI-TOF MS based glycan structure identification, including α-2,3/ α-2,6 differential sialylation

Sample preparation includes :

  • Glycoprotein fraction isolation
  • Glycan release and labeling
  • Chromatographic separation and glycan profiling.

Additional services:

  • MALDI-TOF MS differential sialylation analysis
  • MS/MS fragmentation for glycan structures confirmation or unknown structures identification
  • Glycosidase treatment
