Table I. Mass spectrometric data of desialylated N-glycans released from C-CAM.
Mass spectrometric analysis of the desialylated oligosaccharides from C-CAM was performed by MALDI-TOF-MS. Detected ions could be interpreted as Na-adducts (M+Na)+ of the glycans. Mcalc refers to the calculated average molecular mass (in daltons) summed from the likely carbohydrate composition plus the 2-AB-label. Open squares, N-acetyl-D-glucosamine; solid circles, D-mannose; shaded diamonds, D-galactose; solid triangles, L-fucose.
aValues are rounded.
bOS-fraction, Oligosaccharide fraction numbers correspond to peak numbers in Figure 1.
