Fig. 1. N-glycan composition in AML cell lines.
a MALDI-TOF MS spectra of permethylated N-glycans released from U/A and U937 cells, respectively. b Histograms of relative intensities of the differential N-glycan signals from the both cell lines were observed. c The lectin microarray further determined the differential expression of lectin between U/A and U937 cells. d FCM was used to detect the MAN-M, ConA and AAL lectin expression in AML cell lines
