Title |
relA spoT ESP 3 |
Sample type |
mixed |
|
|
Channel 1 |
Source name |
SL1344 cDNA ∆relA ,∆spoT OD600 = 2.3 replicate 3
|
Organism |
Salmonella enterica subsp. enterica serovar Typhimurium str. SL1344 |
Characteristics |
strain: SL1344 growth phase: early stationary genotype/variation: ∆relA, ∆spoT
|
Growth protocol |
Salmonella strains were innoculated 1/100 from 5 ml over night cultures into 25 ml Lb (10g NaCl) in 250 ml flasksand grown at 37°C in a shaking water bath. When the required OD600 was reached 10 ml culture was removed and mixed with 2 ml 5% Phenol, 95% Ethanol, shaken for 20 seconds then stored on ice for 20 min. Cells were then harvested by centrifugation and RNA extracted.
