| Channel 2 |
| Source name |
pBAD_CTRL_BR3
|
| Organism |
Salmonella enterica |
| Characteristics |
cell (plasmid): Salmonella enterica serovar Typhimurium SL1344 (pBAD-CTRL)
|
| Growth protocol |
S. Typhimurium was grown in LB under aeration until A600=1.5 was reached. L-arabinose was then added to a 0.2% final concentration. Total RNA was isolated 10min after L-arabinose addition.

| Hybridization protocol |
Slides blocked with DCE according to protocol at PMID 11266573. For hybridisation and washing protocols see http://www.ifr.ac.uk/safety/Microarrays/default.html#protocols
|
| Scan protocol |
Axon GenePix4000A, 10nm resolution scan & see http://www.ifr.ac.uk/safety/Microarrays/default.html#protocols
|
| Description |
Intensity ratios of RNA (channel 2) divided by DNA (channel 1) signals minus respective background signals. Total array is 16 blocks arranged in 4X4 configuration.
|
| Data processing |
Data centring was performed by bringing the median ratio (Cy5/Cy3) for each of the 16 blocks to one using the following equation: (Ti) = (Cy5i/Cy3i) - c, where T is the centred ratio, i is the gene index, Cy5 and Cy3 are the red and green intensities and c is the 50th percentile of all Cy5/Cy3 ratios.
