Growth on DC (Na deoxycholate). (A) Western blot of envelope preparations isolated from KKV884 cells expressing the mutant porins from the pNL9 plasmid. (B) Growth of KKV884 cells expressing WT or mutant OmpU porins in the presence of the indicated concentrations of DC (+ DC) relative to that in the absence of DC (− DC). The symbols and error bars show the averages ± standard errors of the means of the ratios of the OD₅₉₀ values obtained from three independent colonies at the 4-h time point.
