(a) More N-glycans were detected and imaged from FFPE mouse brain tissue section by using the novel SubAP/MALDI-MS platform. (b) The Venn diagram showing the overlap of N-glycans detected in this study with N-glycans reported in prior studies (Refs. 32 & 33) using vacuum MALDI-MS platform. (c) H&E stained FFPE mouse brain section post N-glycan imaging. (d-f) MS images of representative N-glycans detected from FFPE mouse tissue section. (g-h) Overlap of different N-glycan images clearly revealed different spatial distribution patterns of N-glycans on mouse brain section.
