"Initial data analysis was performed using the GeneChip® Operating Software. Microarray quality control parameters were as follow: noise (RawQ) less than 5, background signal less than 40 (100 target intensity for array scaling), consistent numbers of genes detected as present across arrays."

"Total RNA was isolated using a RNeasy® RNA isolation kit, according to the manufacturer’s specifications (QIAGEN, Germany) and stored in RNase-free water at –80°C. RNA concentration was determined by UV-spectrometry and its quality controlled by agarose gel electrophoresis."	"extract_protocol_ch1.1"
"Cells used for expression analysis were grown in minimal medium (Glansdorff, 1965) supplemented with 0.5% glucose (w/v), L-methionine (100ug ml-1). For expression analysis, cells were grown in a rotary shaker at 37°C and harvested by centrifugation at mid-log phase ( (OD) 660nm = 0.5) and the metabolism was quenched in liquid nitrogen."
