Sample GSM140689 Query DataSets for GSM140689
Status Public on Oct 19, 2006
Title Sigma70_ChIP_A_cy5
Sample type genomic
 
Source name E. coli MG1655
Organism Escherichia coli
Characteristics Strain MG1655
Extracted molecule genomic DNA
Extraction protocol Cells were fixed in 1% formaldehyde at room temperature for 20 min, quenched with glycine, and lysed. Chromatin was pelleted and solublized by sonication. Crosslinked chromatin was then immunoprecipitated.
Label Cy5
Label protocol ChIP DNA was first denatured and 2-cycle-amplified amplified using primer A (5'-GTTTCCCAGTCACGATCNNNNNNNNN); the resulting DNA was then subjected to a 35-round amplification using primer B (5'-TCCCAGTCACGATC).
 
Hybridization protocol Labeled DNA was hybridized and scanned using proprietary methods (NimbleGen).
Scan protocol Labeled DNA was hybridized and scanned using proprietary methods (NimbleGen).
Description ChIP DNA
Data processing Linearly scaled so that intensity values in Sigma70_ChIP_control_A_cy3, Sigma70_ChIP_A_cy5, Sigma70_ChIP_control_B_cy3, Sigma70_ChIP_B_cy5, Beta_ChIP_control_A_cy3, Beta_ChIP_A_cy5, Beta_ChIP_control_B_cy3, Beta_ChIP_B_cy5 are comparable
