Sample GSM71578 Query DataSets for GSM71578
Status Public on Aug 31, 2005
Title Swi6_2_wt
Sample type genomic
 
Channel 1
Source name Schizosaccharomyces pombe whole cell extract (WCE) genomic DNA
Organism Schizosaccharomyces pombe
Characteristics Chromatin DNA isolated from paraformaldehyde cross-linked wild type Schizosaccharomyces pombe cells
Treatment protocol Schizosaccharomyces pombe cells crosslinked with paraformaldehyde
Growth protocol Asynchronous growing fission yeast cells at 30 C and cross-linked at 18C with paraformaldehyde for 30 minutes
Extracted molecule genomic DNA
Extraction protocol Chromatin was extracted from cross-linked cells following lysis with bead beater and sonication. After reverse cross-linked and digested with Rnase A and proteinase K, DNA was recovered by phenol/chloroform extraction and ethanol precipitation
Label Cy3
Label protocol WCE DNA after amplified by random priming PCR incorporating amino-allyl dUTP was covalently coupled with Cy3 mono NHS ester in 100 mM sodium bicarbonate for 1 hr at room temperature. Labeled DNA was recovered by Qiagen QIAquick PCR column
 
Channel 2
Source name Schizosaccharomyces pombe chromatin immunoprecipitated DNA
Organism Schizosaccharomyces pombe
Characteristics Chromatin DNA isolated from paraformaldehyde cross-linked wild type Schizosaccharomyces pombe cells and enriched for Swi6 chromatin with anti-Swi6 antibody.
Treatment protocol Schizosaccharomyces pombe cells crosslinked with paraformaldehyde
Growth protocol Asynchronous growing fission yeast cells at 30 C and cross-linked with paraformaldehyde at 18C for 30 minutes
Extracted molecule genomic DNA
Extraction protocol Chromatin was extracted from cross-linked cells following lysis with bead beater and sonication. After reverse cross-linked and digested with Rnase A and proteinase K, DNA was recovered by phenol/chloroform extraction and ethanol precipitation
Label Cy5
Label protocol ChIP DNA after amplified by random priming PCR incorporating amino-allyl dUTP was covalently coupled with Cy5 mono NHS ester in 100 mM sodium bicarbonate for 1 hr at room temperature. Labeled DNA was recovered by Qiagen QIAquick PCR column
 
 
Hybridization protocol 500 ng of Cy3 labeled WCE DNA was mixed with 500 ng of Cy5 labeled ChIP DNA plus 50 ul Agilent 10X control targets and 250 ul of 2X Agilent Hybridization buffer
Scan protocol Slides were scanned using Agilent scanner and image intensity data were extracted and analyzed with Agilent Feature Extraction software version 7.5
Description Schizosaccharomyces pombe cells, Swi6 ChIP(chromatin immunoprecipitation)-on-chip, replicate 2
Data processing Log ratios of ChIP over WCE were obtained by dividing normalized median Cy5 value over its corrresponding Cy3 value
