Sample GSM443809 Query DataSets for GSM443809
Status Public on Oct 19, 2009
Title WT_pBAD_CTRL_BR1
Sample type mixed
 
Channel 1
Source name Reference genomic DNA
Organism Salmonella enterica
Characteristics reference: Salmonella enterica serovar Typhimurium SL1344 genomic DNA
Extracted molecule genomic DNA
Extraction protocol Genomic DNA isolated using the Qiagen 'Genomic DNA' Kit (Cat. No.: 19060 for the buffer kit; 10243 for the columns)
Label Cy3
Label protocol Labelling protocol at http://www.ifr.ac.uk/Safety/Microarrays/default.html#protocols
 
Channel 2
Source name WT_pBAD_CTRL_BR1
Organism Salmonella enterica
Characteristics cell (plasmid): Salmonella enterica serovar Typhimurium SL1344 (pKP8-35)
Growth protocol Strain SL1344 was transformed with plasmids pKP8-35 (pBAD-control) and grown in liquid culture inoculated 1:100 from an overnight culture to an OD600 of 1.5. Expression from the pBAD promoter was induced with L-arabinose (0.2% final concentrations) for 10 min.
Extracted molecule total RNA
Extraction protocol Total RNA isolation protocol at http://www.ifr.ac.uk/safety/Microarrays/protocols.html
Label Cy5
Label protocol Labelling protocol at http://www.ifr.ac.uk/safety/Microarrays/protocols.html
 
 
Hybridization protocol Slides blocked with DCE according to protocol at PMID 11266573. For hybridisation and washing protocols see http://www.ifr.ac.uk/safety/Microarrays/default.html#protocols
Scan protocol Axon GenePix4000A, 10nm resolution scan & see http://www.ifr.ac.uk/safety/Microarrays/default.html#protocols
Description Intensity ratios of RNA (channel 2) divided by DNA (channel 1) signals minus respective background signals. Total array is 16 blocks arranged in 4X4 configuration.
Data processing Data centring was performed by bringing the median ratio (Cy5/Cy3) for each of the 16 blocks to one using the following equation: (Ti) = (Cy5i/Cy3i) - c, where T is the centred ratio, i is the gene index, Cy5 and Cy3 are the red and green intensities and c is the 50th percentile of all Cy5/Cy3 ratios.
