Figure 2. LOS profiles and LOS OS structures of the C. jejuni wild-type strains (NCTC 11168 and 81-176) and mutants.

Figure 2

(A) LOS samples were analyzed by tricine-SDS-PAGE using 16% tricine gels and visualized by silver staining. The positions of the protein size markers are indicated on the left of each panel. (B) The LOS structures of 168hldE, 168hldD, 168cj1135, 168cj1136, 168cj1138, 817hldE, and 817hldD were analyzed by MALDI-TOF MS and GC-MS in this study. The wild-type strains and other mutants with asterisks have structures similar to those determined in previous studies [24]–[26], [52]–[54]. Abbreviations, refer to the legend of Fig. 1.
