Sample GSM4230308 Query DataSets for GSM4230308
Status Public on Dec 22, 2020
Title H3K9me2 ChIP in tor2ts ubi4D cells
Sample type genomic
 
Channel 1
Source name H3K9me2 ChIP_tor2ts ubi4D
Organism Schizosaccharomyces pombe
Characteristics growth temperature: cells growing in 30C
genotype: tor2ts ubi4D cells
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 25˚C. For GFP and c-MYC ChIPs, fixed cultures were subjected to additional crosslinking with 10 mM DMA for 45 min at room temperature.
Growth protocol Standard conditions were used to produce logarithmically growing cultures in rich media (YEA). Cultures were grown at 30˚C.
Extracted molecule genomic DNA
Extraction protocol Fixed cells were lysed with glass-beads, DNA sheared by sonication to 400-600bp fragments and immunoprecipitated with H3K9me2 antibody (Abcam, ab1220), c-MYC antibody (Biolegend, 9E10), or 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 Whole-cell extract DNA
Organism Schizosaccharomyces pombe
Characteristics growth temperature: cells growing in 30C
genotype: tor2ts ubi4D cells
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 25˚C. For GFP and c-MYC ChIPs, fixed cultures were subjected to additional crosslinking with 10 mM DMA for 45 min at room temperature.

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.
Description ChIP was performed using anti-H3K9me2 antibody (ab1220) followed by microarray analysis
Data processing Data were extracted using Agilent Feature Extraction Software (CHIP-v1_95_May07 or ChIP-v1_10_Apr08 protocol). Signal was normalized by combined rank consistency filtering with LOWES intensity normalization.
