| Title |
M9TMP_AA_120min |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
E. coli MG1655 120 min after TMP+glycine+methionine treatment in M9 media
|
| Organism |
Escherichia coli |
| Characteristics |
strain: MG1655
|
| Treatment protocol |
Time-point samples were taken every 15-30 minutes from 15 minutes to 2 hours post treatment.
|
| Growth protocol |
Overnight cultures were resuspended in fresh medium and TMP was added when the optical density (O.D. 600 nm) of the culture reached 0.3-0.4.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA samples were purified using the Qiagen RNeasy kit (Chatsworth, CA) according to the manufacturer’s protocol.
|
| Label |
Cy5
|
| Label protocol |
Fluorescence DNA probes were synthesized from 10~15 μg of total RNA with random hexamers and Cy-5 dUTP or Cy-3 dUTP dyes.

| Label |
Cy3
|
| Label protocol |
Fluorescence DNA probes were synthesized from 10~15 μg of total RNA with random hexamers and Cy-5 dUTP or Cy-3 dUTP dyes.
|
| |
|
| |
| Hybridization protocol |
Relative mRNA levels were determined by parallel two color hybridization at single-gene resolution to whole-genome E. coli K-12 MG1655 spotted DNA microarrays
|
| Scan protocol |
Images were scanned using Axon GenePix scanner.
