| Title |
MG1655, biological rep 5 |
| Sample type |
RNA |
| |
|
| Source name |
MG1655 exponentially grown in the minimal medium
|
| Organism |
Escherichia coli |
| Characteristics |
strain: MG1655 (parent)
growth protocol: steady growth
|
| Treatment protocol |
The cell culture was put into cold phenol-ethanol solution (1 g of phenol in 10 mL of ethanol) prepared in advance. The cells were collected by centrifugation at 16,000 × g for 5 min at 4°C, and the pelleted cells were stored at –80°C prior to use.
|
| Growth protocol |
Cells were grown in the minimal media, M63. The final cell concentrations were controlled ~ 108 cells/mL within the exponential growth phase.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNAs were extracted using an RNeasy mini kit (Qiagen) in accordance with the manufacturer’s instructions.
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 10 ug total RNA (Expression Analysis Technical Manual, Affymetrix).
|
| |
|
| Hybridization protocol |
Following fragmentation, 3 ug of cRNA were hybridized for 16 hr at 45°C on Affymetrix GeneChip Hybridization Oven 640. GeneChips were washed and stained in the Affymetrix GeneChip Fluidics Station 450.
|
| Scan protocol |
GeneChips were scanned using the Affymetrix GeneChip Scanner 7G.
|
| Description |
final cell concentration ~ 10^8 cells/mL
|
| Data processing |
Microarray data were processed using custom scripts written in R based on the finite hybridisation (FH) model (Ono et al, 2008) and the thermodynamic model of non-specific binding (NSB) on short nucleotide microarrays (Furusawa et al, 2009).
The log10 mRNA concentration (pM) data are provided as a supplementary file on the SERIES record.
