Title |
OSU12-hisG, histidine depleted, 2 hrs, rep 2 |
Sample type |
RNA |
|
|
Source name |
OSU12-hisG, histidine depleted, 2 hrs
|
Organism |
Escherichia coli |
Characteristics |
strain: DH1 ΔhisG::cat ΔintC::Ptrc-dsred.t4-tetR-PEM7-zeo ΔgalK::PtetA-gfpuv5 condition: histidine depleted
|
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, modified M63. The final cell concentrations were controlled ~ 10^8 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.
|
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.
