Fig. 2. (A) MS spectra of MCF-7 cells after incubation with (a) Au-MT1, (b) Au@BSA-MT1, (c) Au@ConA-MT1, (d) Au@SNA-MT2, (e) Au@WGA-MT3 and (f) the mixture of Au@ConA-MT1, Au@SNA-MT2 and Au@WGA-MT3 (893.6, [2MT1-H2S–S + Na]+; 925.6, [2MT1-H2S + Na]+; 957.6, [2MT1-H2 + Na]+; 717.5, [2MT2-H2S–S + Na]+; 749.5, [2MT2-H2S + Na]+; 781.5, [2MT2-H2 + Na]+; 805.6, [2MT3-H2S–S + Na]+; 837.6, [2MT3-H2S + Na]+; 869.6, [2MT3-H2 + Na]+; * refers to Aun+). (B) MCF-7 monosaccharide inhibition assay. LCMPs were pre-incubated with several monosaccharides before being labeled on the cell surface. Y-axis is the mass spectrometric signal intensity of LCMPs.
