| Title |
Haloferax mediterranei ΔdeoR2 with induction by fructose vs without induction replicate 1 |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
ΔdeoR2_induced by fructose
|
| Organism |
Haloferax mediterranei |
| Characteristics |
strain: DF50
genotype/variation: ΔdeoR2
induced by: fructose (at final conc. 50mM)
|
| Treatment protocol |
fructose (soluted in TBSL buffer) was added into the culture to a final concentration of 50mM, and a same volume TBSL buffer was added into the other culture, both two were incubated for 45 before harvested.
|
| Growth protocol |
Cells of H. mediterranei DF50 or DF50 delta deoR2 were grown at 37°C until OD600 reached 1.5 in AS-168SYL medium,
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA extracted using Trizol (invitrogen) following manufacturer's instructions
|
| Label |
cy3
|
| 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 strain DF50 delta deoR2 under the induction by fructose
|
| 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, lowess normalized log2 ratio (test/control) was calculated.
