Interaction with AcrA. Anti-AcrA Western blot analysis (top panel) of co-purified AcrA from BW25113ΔacrB expressing wild type or mutant AcrB. The empty vector pQE70 was used as the negative control. The same gel was stained using Coomassie blue stain (bottom) to reveal that similar amount of AcrB was present in each sample.
