The presence of pInter decreased the level of hydroxyl radicals present in norfloxacin-treated cells E. coli BW27784 with control vector or pInter were grown to exponential phase before treatment with 250 ng/ml norfloxacin. HPF was added 2 h later for fluorescence detection of hydroxyl radicals by flow cytometry. The results represent a single experiment out of four independent experiments (p < 0.05 for decrease in fluorescence after norfloxacin treatment due to the presence of pInter).
