Fig. 4. The MS imaging of ConA–probe 1 (orange): mannose; RCA120–probe 2 (blue): Galβ group; WGA–probe 3 (green): N-acetylglucosamine and sialic acids; and SNA–probe 4 (red): Neu5Aca2-6Gal(NAc)-R; and the co-localized MS imaging of these four glycans using an equal molar mixture of lectin–probes. The mass spectrum is shown in the ESI (Fig. S26†). HE staining is short for hematoxylin and eosin staining.
