Characterization of H. suis binding glycosphingolipids from pig stomach. A. Thin-layer chromatogram after detection with anisaldehyde B. Autoradiogram obtained by binding of 35S-labeled H. suis (HS5) at pH 7.2. C. Autoradiogram obtained by binding of 35S-labeled H. pylori strain J99 wt at pH 7.2. The glycosphingolipids were separated on aluminum-backed silica gel plates, using chloroform/methanol/water 60:35:8 (by volume) as solvent system. Lanes 1–4 were total non-acid glycosphingolipids isolated from the stomach of four individual pigs, 40 µg/lane. D-G. LC-ESI/MS of the oligosaccharides obtained by digestion of the non-acid glycosphingolipid fraction of pig stomach (shown in chart A, lane 2) with Rhodococcus endoglycoceramidase II. D. Base peak chromatogram from LC-ESI/MS of the oligosaccharides derived from the non-acid glycosphingolipid fraction of pig stomach. E. MS2 spectrum of the ion at m/z 706 (retention time 14.2 min). F. MS2 spectrum of the ion at m/z 706 (retention time 18.3 min). G. MS2 spectrum of the ion at m/z 706 (retention time 18.5 min). H. Interpretation formulas showing the deduced oligosaccharide structures.
