Figure 3. HPAEC-PAD separation of native and oxidized xylo-oligosaccharides.

Figure 3

(A): Xylo-oligosaccharide standard from xylose to xylohexaose (X1 to X6, respectively) before oxidation (top) and after the oxidation of CtCBM22A_GOOX-VN, which released oxidized xylose to xylohexaose (ox.X1 to ox.X6, respectively) (bottom). (B): A chromatogram of soluble oat spelt xylan without any enzyme treatment. (C): Xylanase treatment of soluble oat spelt xylan (black solid), GOOX-VN treated soluble oat spelt xylan (red dashed) and CtCBM22A_GOOX-VN treated soluble oat spelt xylan (green dotted dashed); peaks formed by oxidation were asterisked.
