O-glycan profiling of mucin from porcine stomach (MPS) by ESI-MS. The MPS type III (MPS3) contains 0.5-1.5% sialic acid. A total of 80 O-GalNAc glycans were identified from MPS3. The identified O-glycans are consistent with what has been reported in the literature60. Image adapted with permission from ref. 37, Nature Publishing Group.
