MALDI ToF MS of GalGlcn standards, prior to and after reduction with NaBD4. The non-reduced compounds shown in (A), GalGlc3 (at m/z 689 with a little bit of unreacted Glc3 at m/z 527), and (C), GalGlc4 (at m/z 851 with a little bit of unreacted Glc4 at m/z 689), yield masses equivalent to cello-oligosaccharides. The reduced compounds (B) and (D) show an expected m/z of + 3, reflecting reduction and the incorporation of one D (see Fig. 4 for structures). (E) Shows route for generating GalGlcn (n = 3 or 4) standards. The spectra were generated with Flex analysis 3.4, https://www.bruker.com.
