Transcriptional profiling of E. coli cultures exposed to tellurite 0.5 µg/ml

E. coli cultures were exposed to tellurite 0.5 µg/ml during 15 min. Total RNA was extracted and cDNA labeled probes were generated by reverse transcription using Alexa 555 and Alexa 647 fluorophores. These probes were used to hybridize genomic slides containing genomic arrays to determine global transcriptional changes. Two-conditions experiment, antibacterial vs. Untreated control cells. Biological replicates: 2 control, 2 toxicants exposed cells, independently grown and harvested. One replicate per array. Dye swap conditions.
