Expression data from PAO1 and its creBC derivative mutant (PAOΔcreBC). Pseudomonas aeruginosa

We used microarrays to determine the expression profile of the P. aeruginosa creBC mutant regarding its parental wild type strain PAO1. Overall design: Expression analysis from three independent replicates of PAO1 and its creBC derivative mutant (PAOΔcreBC) were performed under basal conditions and with cefoxitin and ceftazidime. cDNA synthesis, fragmentation, labeling and hybridization were performed according to the Affymetrix GeneChip P. aeruginosa genome array expression analysis protocol.
