Figure 2. LPS analysis of rcsB (A) and pmrA (B) mutants of S. Enteritidis strains.

Figure 2

Equal amount of LPS was loaded in each lane and analyzed by Tricine/SDS-PAGE on a 14% (w/v) acrylamide gel followed by silver staining. The concentration of LPS was determined by measuring KDO using the purpald assay. Plasmids prcsB and ppmrA bears the rcsB and pmrA genes respectively.
