A strategy for the construction of the mouse glycome atlas. (a) An image representation for the glycoblotting-based solid-phase glycan enrichment analysis for the construction of mouse tissue glycome atlas. (b) In the present study, sixteen frozen organs/tissues in addition to the serum and serum-derived exosomes were employed for the general protocol enabling one-pot rapid and efficient glycan enrichment and subsequent chemical manipulations on the polymer-solid beads. Pie charts represent ratio of the terminal sugar residues of each organ revealed by glycotyping analysis17,18,37,49 of the present results. (c) General biosynthetic pathway of major N-glycans showing maturation from high mannose-type to hybrid-type and complex-type glycoforms in the posttranslational modification of mammalian proteins. This schematic representation does not involve the biosynthesis of minor glycoforms having GalNAc terminals, Lewis type antigenic structures, lactosaminoglycans (LacNAc repeats), sulfated sugar moieties, and so on. (d) The sugar compositions of N-glycans assigned based on the reported structures may often predict multiple candidates of the isomeric glycoforms found in the Expasy GlycoMod Tool (https://web.expasy.org/glycomod/ and https://glyconnect.expasy.org/browser/compositions/453).
