| Title |
Cortisol treated log phase, rep3 |
| Sample type |
mixed |
| |
|
| Channel 1 |
| Source name |
S. Typhimurium, cortisol treated, log phase
|
| Organism |
Salmonella enterica subsp. enterica serovar Typhimurium |
| Characteristics |
strain: 112910a
growth phase: log
treatment: cortisol
|
| Treatment protocol |
Cortisol-treated cultures contain 1 µM of cortisol.
|
| Growth protocol |
Stationary phase cultures were obtained by aerated, overnight culture at 37 °C in 5 mL LB in 50 mL flasks. To obtain highly invasive late logarithmic cultures, 2 µL of a stationary phase culture was inoculated in 5 mL LB and grown for 5 hours at 37 °C without aeration.

| Hybridization protocol |
Slides were blocked with DCE according to the protocol at PMID 11266573. For hybridisation and washing protocols, see http://www.ifr.ac.uk/safety/Microarrays/protocols.html
|
| Scan protocol |
Axon GenePix4000A 10 µm resolution scan. See http://www.ifr.ac.uk/safety/Microarrays/default.html#protocols.
|
| Data processing |
Intensity ratios of channel 1 (cDNA) divided by channel 2 (reference gDNA) signals are calculated using BlueFuse 3.01 (BlueGnome, Cambridge, UK). Data centering was subsequently performed using block median normalization.
