| Title |
Bexp_Kexp_dyeswap2 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
MG1655, exponential phase, LB
|
| Organism |
Escherichia coli |
| Characteristics |
MG1655, exponential phase, LB
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from cells grown in LB medium using the Qiagen RNeasy column.
|
| Label |
Cy3
|
| Label protocol |
Fluorescently-labeled cDNA was synthesized by reverse transcription of total RNA with aminoallyl-dUTP and random primers followed by the coupling of Cy3 or Cy5 dyes (Amersham Pharmacia).

| |
|
| Channel 2 |
| Source name |
REL606, exponential phase, LB
|
| Organism |
Escherichia coli |
| Characteristics |
REL606, exponential phase, LB
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was isolated from cells grown in LB medium using the Qiagen RNeasy column.
|
| Label |
Cy5
|
| Label protocol |
Fluorescently-labeled cDNA was synthesized by reverse transcription of total RNA with aminoallyl-dUTP and random primers followed by the coupling of Cy3 or Cy5 dyes (Amersham Pharmacia).
|
| |
|
| |
| Hybridization protocol |
Hybridization and washes were performed according to the instruction of the manufacturer (Digital Genomics).
|
| Scan protocol |
The hybridized slides were scanned with GenePix 4000B (Molecular Devices) and scanned images were analyzed by GenePix Pro 6.0.
|
| Description |
The microarray contains two large blocks, onto each of which the probes were spotted in duplicate. The data is for one of the blocks (dye-swap experement).
|
| Data processing |
Following background subtraction, spot signal intensities were calculated as percentages of total signal intensities of Cy-3 or Cy-5 signals on each microarray, as a means of normalization. Spots with low intensities were excluded.
