Description
Multidrug resistant mutant derived from Ecl8 George et al (1995) Microbiology 141 ( Pt 8):1909-20
Data processing
After QC assessment to identify substandard arrays, raw data were subjected to quantile normalization (Bolstad et al. Bioinformatics 19(2):185), and background correction as implemented in the NimbleScan software package, version 2.4.31 (Roche NimbleGen, Inc.). Probe level data were summarised to yield gene level data and differential expression analysis was carried out using Limma (Smyth Stat Appl Genet Mol Biol 3 article 3)
