Sample GSM98723 Query DataSets for GSM98723
Status Public on Mar 06, 2006
Title EC18n168 RpoH 2.5 min Time course 2
Sample type RNA
 
Channel 1
Source name Wild type control (2.5 min)
Organism Escherichia coli
Characteristics MG1655 PhtpG::lacZ delta lacX74/ptrc99A (control vector)
Treatment protocol At OD450 = 0.3, cultures induced with 1 mM IPTG. Cells harvested 2.5 min after induction
Growth protocol M9 minimal complete media, cultures grown aerobically at 30 degrees C in a gyratory water bath shaking at 240 rpm
Extracted molecule total RNA
Extraction protocol Culture samples for microarray analysis were added to ice-cold 5% water-saturated phenol in ethanol solution, centrifuged at 6,600 g and the cell pellets flash frozen in liquid N2 before storing at -80 degrees C until required. Total RNA was isolated from the stored cell pellets using the hot phenol method, and labeled Cy3 and Cy5 cDNA was prepared from 16 ug total RNA with 10 ug random hexamer (Integrated DNA Technologies, Inc., Coralville, IA, USA).
Label Cy3
Label protocol Indirect labeling method as described in Khodursky et al (2003; Methods Mol Biol 224:61-78)
 
Channel 2
Source name RpoH induced (2.5 min)
Organism Escherichia coli
Characteristics MG1655 PhtpG::lacZ delta lacX74/pTG2 (vector carrying inducible Ptrc::rpoH)
Treatment protocol At OD450 = 0.3, cultures induced with 1 mM IPTG. Cells harvested 2.5 min after induction
Growth protocol M9 minimal complete media, cultures grown aerobically at 30 degrees C in a gyratory water bath shaking at 240 rpm
Extracted molecule total RNA

Label Cy5
Label protocol Indirect labeling method as described in Khodursky et al (2003; Methods Mol Biol 224:61-78)
 
 
Hybridization protocol cDNA from 16 ug total RNA, 15 ug poly(dI-dC), 3xSSC, 25 mM Hepes (pH7), 0.225% SDS. Samples hybridized on array under a lifterslip for 12 hrs at 65 degrees C
Scan protocol Slides scanned using GenePix 4000B scanner (Axon). TIFF images analyzed using GENEPIX 3.0 software (Axon).
Description Wild type vs RpoH (Sigma 32) 2.5 min after overexpression
Data processing Data filtered for PCR success, >3x local background and spot quality (GenePix Flag). Normalized using Lowess smoothing from MA plot
