Sample GSM2802868 Query DataSets for GSM2802868
Status Public on May 08, 2018
Title CCR4 deletion and feb1 mutant H3K9 dimethyl ChIP grown a18C
Sample type genomic
 
Channel 1
Source name log. growing cells
Organism Schizosaccharomyces pombe
Characteristics genotype/variation: CCR4 deletion and feb1 mutant
fraction: H3K9me2 immunoprecipitated DNA
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at room temperature. For Fep-GFP ChIP, cells were further crosslinked with DMA for 45 min at room temperature.
Growth protocol Standard conditions were used to produce logarithmically growing cultures in rich media (YEA). In ChIP experiments performed at 30°C, cultures were grown at 30˚C to OD600~0.5. In ChIP experiments performed at 18°C, cultures were first grown at 30°C to OD600~0.1-0.2 and then shifted to 18˚C for 3 days.
Extracted molecule genomic DNA
Extraction protocol Fixed cells were lysed with glass-beads, DNA sheared by sonication to 500-1000bp fragments and immunoprecipitated with H3K9dime antibody (Abcam, ab115159), or with GFP antibody (Abcam, ab290). Immunoprecipitated DNA was recovered by incubation with protein A/G 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 strain: smt0
fraction: Whole-cell extract DNA
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at room temperature. For Fep-GFP ChIP, cells were further crosslinked with DMA for 45 min at room temperature.
Growth protocol Standard conditions were used to produce logarithmically growing cultures in rich media (YEA). In ChIP experiments performed at 30°C, cultures were grown at 30˚C to OD600~0.5. In ChIP experiments performed at 18°C, cultures were first grown at 30°C to OD600~0.1-0.2 and then shifted to 18˚C for 3 days.

Immunoprecipitated DNA was recovered by incubation with protein A/G 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_1200_Jun14 protocol). Signal was normalized by combined rank consistency filtering with LOWES intensity normalization.
