From: Synergistic effect of imp/ostA and msbA in hydrophobic drug resistance of Helicobacter pylori

The effect of imp/ostA on the transcription of msbA after glutaraldehyde treatment and vice versa. Slot blots analysis of total RNA preparations of H. pylori NTUH-S1 wild-type and mutants after 0.5 μg/ml glutaraldehyde treatment for 48 h. Each well was loaded with 10 μg total bacterial RNA. The membrane was hybridized with DIG-labeled probes specific for H. pylori imp/ostA, msbA, and 23S rRNA.
