| Title |
compare WT/mutant SG-A |
| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
SG511 mutant R
|
| Organism |
Staphylococcus aureus |
| Characteristics |
genotype/variation: dapto R
strain: SG511
genotype/variation: wildtype
|
| Treatment protocol |
RNA Protect (Qiagen)
|
| Growth protocol |
S. aureus strains were grownup to OD600=0.8 in MHB (Becton Dickinson) enriched with 1.25 mM CaCl2
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Briefly, bacteria were stabilized in RNA protect for 5 minutes, then harvested. Cells were lysed in the presence of 600 µg/ml lysostaphin and total RNA was extracted using the PrestoSpin R bug Kit including DNase I treatment (Molzym). Quantity and absence of contaminating DNA was measured by using the Nanodrop spectrophotometer (Nanodrop Technologies), and by qPCR, respectively.

| Label |
cyanine 5
|
| Label protocol |
Incorporation of cyanine dye during reverse transcription
|
| |
|
| |
| Hybridization protocol |
A mixture of cDNA obtained from reverse transcription of RNA from WT or mutant strains were diluted in 50 µl Agilent hybridization buffer, and hybridized at a temperature of 60°C for 17 hours in a dedicated hybridization oven
|
| Scan protocol |
100% PMT using Agilent scanner
|
| Description |
SG511 parental strain
|
| Data processing |
Local background-subtracted signals were corrected for unequal dye incorporation or unequal load of labelled product. Per chip and per spot normalisation wee performed in GeneSpring (7.3)
