Expression of the sialylated oligosaccharides of N-glycoproteins in the clinical specimens of primary and secondary central nervous system (CNS) lymphomas. a Oligosaccharide types of N-glycoproteins. Ratios of oligosaccharides in each specimen are shown. The numbers in the graph represent the average ratios of oligosaccharides of four samples. b Relative expression of neutral and sialylated oligosaccharides of N-glycoproteins in the four clinical specimens. Average expression of N-oligosaccharides and their relative expression among the specimens are shown. Color configuration indicates high (red) to low (green). NA; not applicable. c Sialylation of oligosaccharides of N-glycoproteins. Ratios of α2,3- and α2,6-sialylation detected are shown
