Heatmaps visualizing the distribution and of human gastric mucin O-glycans from noninfected and Helicobacter spp.-infected stomachs.A, the composition of all 631 glycans. Please note that the fact that several of the blood group B and AB individuals appears to have increased levels of Hex may be due to that we were not able to assign these structures from the composition. B, the average number of histo-blood group motifs per glycan among the 145 fully characterized glycans. C, the average number of core structures among the 145 fully characterized glycans. Se− denotes secretor-negative individuals based on their low amount of blood group structures identified (<0.1%). SS denotes that the glycans are from GuHCl soluble mucins from the antral surface, SI insoluble mucins from antral surface, DS soluble mucins from the antral glands, and DI insoluble mucins from the antral gland and MSAC. MSAC, MS based average composition; GuHCl, guanidinium chloride.
