Fig. 3. Histograms of ion abundances of the four lectin–probes (m/z 250.05, 264.02, 278.10 and 292.18) from MCF-7 (n = 100) and MCF-7R cells (n = 100), which corresponded to glycans with the α-d-mannosyl and α-d-glucosyl groups, Galβ group, N-acetylglucosamine, sialic acids and Neu5Aca2-6Gal(NAc)-R, respectively. These results show that drug resistance selectively influences the expression of glycans.
