Sample GSM629243 Query DataSets for GSM629243
Status Public on Jan 07, 2011
Title H3K9ac in asf1-1 cells
Sample type genomic
 
Channel 1
Source name log. growing cells
Organism Schizosaccharomyces pombe
Characteristics cell type: asf1-1
antibody: H3K9ac
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 18˚C.
Growth protocol Standard conditions were used to produce logarithmically growing cultures in rich media (YEA) at 30˚C.
Extracted molecule genomic DNA
Extraction protocol Fixed cells were lysed with glass-beads, DNA sheared by sonication to 500-1000bp fragments and immunoprecipitated by appropriate antibody: H3K9ac (Upstate). Immunoprecipitated DNA was recovered by incubation with protein A slurry and reversed-crosslinked at 65˚C.
Label Cy5
Label protocol ChIP and whole-cell extract DNA was amplified by random-primed PCR and conjugated with Cy5 (ChIP DNA) or Cy3 (whole-cell extract DNA).
 
Channel 2
Source name log. growing cells
Organism Schizosaccharomyces pombe
Characteristics cell type: asf1-1
antibody: none
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 18˚C.
Growth protocol Standard conditions were used to produce logarithmically growing cultures in rich media (YEA) at 30˚C.
Extracted molecule genomic DNA
Extraction protocol Fixed cells were lysed with glass-beads, DNA sheared by sonication to 500-1000bp fragments and immunoprecipitated by appropriate antibody: H3K9ac (Upstate). Immunoprecipitated DNA was recovered by incubation with protein A slurry and reversed-crosslinked at 65˚C.
Label Cy3
Label protocol ChIP and whole-cell extract DNA was amplified by random-primed PCR and conjugated with Cy5 (ChIP DNA) or Cy3 (whole-cell extract DNA).
 
 
Hybridization protocol Equal amounts of Cy5-labeled ChIP DNA and Cy3-labeled whole-cell extract DNA were mixed and combined with human Cot1 DNA, Agilent Blocking Agent and Agilent Hybridization buffer, and hybridized to high-density microarrays in Agilent SureHyb hybridization chamber for 24 hours at 65˚C, 10 rpm. After hybridization, slides were washed according to Agilent protocol.
Scan protocol Scanned on an Agilent G2505B scanner.
Data processing Data were extracted using Agilent Feature Extraction Software (CHIP-v1_107_Sep09 protocol). Signal was normalized by combined rank consistency filtering with LOWES intensity normalization. Background signal was estimated as a median processed signal of 152 oligonucleotides with no homology to S. pombe genome.
