LC-ESI-qTOF MS/MS analysis of unknown oligosaccharides (Figure 2) fractionated from Driselase digests of N. benthamiana leaf tissue. Unknown 1, cellobionic acid (A), and unknown 2, xylogluconic acid (B). x-axis, m/z; y-axis, intensity. HPAEC-PAD traces of monosaccharides produced postacid hydrolysis (C) of unknown 1 (glucose and gluconic acid) and unknown 2 (xylose and gluconic acid) with gluconic acid standard. x-axis, time; y-axis, abundance. x-axis, m/z; y-axis, intensity.
