Detectable native glycan fragments and whole gastric cancer tissue section ion map.A, detectable glycan fragments were in the mass range of 190 to 660 m/z and are shown as symbols with numbers. B–D, ion map of N-acetylhexosamine sulphate, hexose sulfate, and hexuronic acid N-acetylhexosamine in whole tissue sections from a gastric cancer patient. Every tissue section corresponds to an individual patient and highlights altered specific distribution of each glycan fragment. Reprinted with permission from reference (52).
