Transcriptional profiling of early stationary phase S. Typhimurium, comparing wild type SL1344 with an isogenic ∆relA,∆spoT strain (JH3370).
Overall design
Each array used labelled cDNA against a common genomic DNA reference. The wild type strain was arrayed in triplicate and the ∆relA,∆spoT strain in quadruplicate using RNA isolated from biologically independent cultures.
