LIF electropherograms of APTS-derivatized AcXOS (A), APTS-derivatized AcXOS from digestion with AxeA1 until the endpoint (B), and APTS-derivatized AcXOS from digestion with Axe7A until the endpoint (C). Insets show the MALDI-TOF mass data of the corresponding oligosaccharides. Masses represent sodium-adducted oligosaccharides. The suggested structures 1 to 8 (B) were defined by using CE-LIF-ESI-MSn (28).
