| Title |
multi-v-ko-3 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
ko
|
| Organism |
Citrobacter rodentium |
| Characteristics |
RegA Knockout
|
| Treatment protocol |
Bicarbonate was added to a final concentration of 45mM
|
| Growth protocol |
overnight cultures of Citrobacter rodentium were inoculated into LB medium to obtain an OD600 of 0.1 and grown until the OD600 was 0.88
|
| Extracted molecule |
total RNA |
| Extraction protocol |
10mL of a culture was incubated with 20mL of RNAprotect solution (Qiagen) at room temperature for 15min. Cells were pelleted and RNA was purified using a FastRNA Pro Blue kit (Qbiogene). RNA samples were Dnase treated (Qiagen) and further purified using an RNeasy MiniElute kit (Qiagen).
|
| Label |
Cy3
|
| Label protocol |
5microg of total RNA was labeled with Cy3-ULS or Cy5-ULS (Kreatech) as per manufacturers instructions

|
| |
| Hybridization protocol |
Hybridization was conducted as per Agilent 2 color microarray-based gene expression analysis manual (version 5.7) with the modification 4 microg of labeled total RNA was used per hybridization.
|
| Scan protocol |
Images were quantified using Agilent Feature Extraction Software.

| Description |
no additional information
|
| Data processing |
Data was normalized within arrays using loess normalization in limma. DE was analyzed in limma with design <- cbind(dye=c(1,1,1,1,1,1,1,1), UnstimKOvMC=c(0,-1,0,-1,0,1,0,1), StimKOvMC=c(-1,0,-1,0,1,0,1,0))
VALUE column below reports normalized log2 (ko/ref) ratios.
