Transcription profiling of acid exposed H. pylori Two independent exposures (labeled T1 and T2) to pH 5.0. Samples were harvested at 30, 60, 90 and 120 minutes
Two independent exposures (labeled T1 and T2) to pH 5.0. Samples were harvested at 30, 60, 90 and 120 minutes and used to make cDNA. Arrays are set up such that each time point was hybridized to the individual T=0 starting culture.
