Abstract

Mucin glycans are associated with the function of mucin in maintaining mucosal homeostasis. Therefore, the glycomic analysis of mucins is crucial. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is one of the most suitable methods for the glycomic analysis of mucin O-glycans. In this chapter, we describe methods for analyzing permethylated O-glycan alditols released from mucins by MALDI-TOF MS and MALDI-TOF tandem mass spectrometry (MALDI-TOF MS/MS).
