Sample GSM322928 Query DataSets for GSM322928
Status Public on Sep 22, 2008
Title multi-bicarb-v-ko-bicarb-1
Sample type RNA
 
Channel 1
Source name multi-bicarb
Organism Citrobacter rodentium
Characteristics RegA multicopy transgene
agent: bicarbonate
Treatment protocol Bicarbonate was added to a final concentration of 45mM
Growth protocol overnight cultures of Citrobacter rodentium were inoculated into LB medium to obtain an OD600 of 0.1 and grown until the OD600 was 0.88
Extracted molecule total RNA
Extraction protocol 10mL of a culture was incubated with 20mL of RNAprotect solution (Qiagen) at room temperature for 15min. Cells were pelleted and RNA was purified using a FastRNA Pro Blue kit (Qbiogene). RNA samples were Dnase treated (Qiagen) and further purified using an RNeasy MiniElute kit (Qiagen).
Label Cy3
Label protocol 5microg of total RNA was labeled with Cy3-ULS or Cy5-ULS (Kreatech) as per manufacturers instructions
 
Channel 2
Source name ko-bicarb
Organism Citrobacter rodentium
Characteristics agent: bicarbonate
RegA Knockout
Treatment protocol Bicarbonate was added to a final concentration of 45mM
Growth protocol overnight cultures of Citrobacter rodentium were inoculated into LB medium to obtain an OD600 of 0.1 and grown until the OD600 was 0.88
Extracted molecule total RNA
Extraction protocol 10mL of a culture was incubated with 20mL of RNAprotect solution (Qiagen) at room temperature for 15min. Cells were pelleted and RNA was purified using a FastRNA Pro Blue kit (Qbiogene). RNA samples were Dnase treated (Qiagen) and further purified using an RNeasy MiniElute kit (Qiagen).
Label Cy5
Label protocol 5microg of total RNA was labeled with Cy3-ULS or Cy5-ULS (Kreatech) as per manufacturers instructions
 
 
Hybridization protocol Hybridization was conducted as per Agilent 2 color microarray-based gene expression analysis manual (version 5.7) with the modification 4 microg of labeled total RNA was used per hybridization.
Scan protocol Images were quantified using Agilent Feature Extraction Software.
Description no additional information
Data processing Data was normalized within arrays using loess normalization in limma. DE was analyzed in limma with design <- cbind(dye=c(1,1,1,1,1,1,1,1), UnstimKOvMC=c(0,-1,0,-1,0,1,0,1), StimKOvMC=c(-1,0,-1,0,1,0,1,0))
VALUE column below reports normalized log2 (ko/ref) ratios.
