| Title |
control wild-type strain vs ΔphaEC strain replicate 1 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
wild-type strain
|
| Organism |
Haloferax mediterranei |
| Characteristics |
Stage: late exponential
strain: wild-type
|
| Treatment protocol |
The wild-type strain and ΔphaEC strain were harvested at the late exponential stage.
|
| Growth protocol |
The wild-type strain and ΔphaEC strain were were cultivated at 37°C to late exponential growth phase in MG medium containing 10 g/L glucose as carbon source.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA extracted using Trizol (invitrogen) following manufacturer's instructions
|
| Label |
cy5
|
| Label protocol |
Fluorescent dye (Cy5 and Cy3-dCTP, Amersham Pharmacia Biotech, Piscataway, NJ) labeled DNA was produced through Eberwine's linear RNA amplification method and subsequent enzymatic reaction. the amplified RNA (aRNA) was purified with NucleoSpin Extract II (MN). We took a cDNA labeling approach with Klenow enzyme after reverse transcription.

| Description |
compare gene expression profiles of wild-type strain with ΔphaEC strain
|
| Data processing |
After background correction and removal of bad spots, a space and intensity-dependent normalization based on a LOWESS program was employed. For each test and control sample, hybridizations were performed by using a reversal fluorescent strategy,the geometric mean of lowess normalized log2 ratio (test/control) of dye-swap slides was calculated. SAM (significance Analysis of Microarrays, version 2.23b) software was used to normalize data.
