Sample GSM826269 Query DataSets for GSM826269
Status Public on Dec 01, 2011
Title H3K9me2 ChIP in ∆epe1 cells
Sample type genomic
 
Channel 1
Source name log. growing cells
Organism Schizosaccharomyces pombe
Characteristics genotype/variation: ∆epe1 cells
antibody: H3K9me2
antibody vendor: Abcam
antibody catalog#: ab1220
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 30˚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 with H3K9dime antibody (Abcam,ab1220). Immunoprecipitated DNA was recovered by incubation with protein 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 genotype/variation: ∆epe1 cells
input: Whole-cell extract DNA
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 30˚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 with H3K9dime antibody (Abcam,ab1220). Immunoprecipitated DNA was recovered by incubation with protein 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-v1_95_May07 or ChIP-v1_10_Apr08 protocol). Signal was normalized by combined rank consistency filtering with LOWES intensity normalization.
