FIG. 1.
LPS profiles of wild-type P. mirabilis (N2), the galU knockout mutant (dG1), the GalU-complemented strain (dG1c), the ugd knockout mutant (dU2), and the Ugd-complemented strain (dU2c). Six microliters of LPS purified from the same number of cells (OD600 × volume [in ml] = 100) of the respective strains was subjected to SDS-PAGE analysis.
