| Title |
vector_control |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
The wild-type strain carrying the vacant vector before IPTG induction
|
| Organism |
Corynebacterium glutamicum R |
| Characteristics |
genotype: Wild type
plasmid: pCRB12iP
|
| Treatment protocol |
To induce sigC overexpression, isopropyl-β-d-thiogalactopyranoside (IPTG) was added at the final concentration of 0.5 mM to exponentially-growing culture. After 15 min, 1 ml of culture was mixed with 1 ml bacterial RNA protect reagent (Qiagen) for RNA stabilization.
|
| Growth protocol |
C. glutamicum strains are grown in 100 ml of nutrient rich A medium containing 1% glucose in 500 ml flask at 33˚C
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted from C. glutamicum cells using NucleoSpin RNA II kit (Macherey-Nagel, Germany) according to the manufacture's manual.
|
| Label |
Cy3
|
| Label protocol |
The cDNAs were synthesized from RNA by using reverse transcriptase from 10 μg of total RNAs and labeled with cyanine 3 (Cy3) or cyanine 5 (Cy5) using the SuperScript Indirect cDNA Labeling system (Life Technologies).

| Hybridization protocol |
Labeled cDNA (4.5 μg each) are mixed with 1 × hybridization buffer (6 × SSC, 0.2% SDS, 5 × Denhardt’s solution, 0.1 mg/ml denatured salmon sperm DNA) in a total volume of 340 μl, and denatured at 95˚C for 2 min. The hybridization mixture was hybridized to a microarray in an Agilent Technologies Microarray chamber at 60˚C for 17 h in a rotating Agilent hybridization oven. After hybridization, microarrays were washed for 5 minutes with wash buffer 1 (2x SSC, 0.2% SDS) at room temperature , 5 minutes with wash buffer 2 (0.2x SSC, 0.2% SDS) at 60˚C, and 5 minutes with wash buffer 3 (0.2x SSC) at room temperature.
|
| Scan protocol |
Slides were scanned immediately after washing on the Agilent DNA Microarray Scanner (G2505C) at a resolution of 5 µm. PMT is set to 100% for Cy3 and Cy5 channels.
|
| Description |
IPTG was added at the final concentration of 0.5 mM during the exponential phase of growth
|
| Data processing |
The scanned images were analyzed quantified with Feature Extraction Software 10.5.5.1 (Agilent) using default parameters (protocol GE2-NonAT_105_Dec08). Feature extracted data were analyzed using GeneSpring GX v 12.5 software from Agilent. Normalization of the data was done in GeneSpring GX using the Lowess normalization algorithm without baseline transformation.
