Sample GSM2042512 Query DataSets for GSM2042512
Status Public on Feb 25, 2017
Title Psc3-GFP ChIP in dcr1d cells
Sample type genomic
 
Channel 1
Source name Psc3-GFP ChIP DNA
Organism Schizosaccharomyces pombe
Characteristics growth stage: log growing cells
genotype/variation: dcr1d cells
antibody: Psc3-GFP
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 30˚C. Prior fixation cells were incubated at 18˚C for 2h (Psc3 and Rec8 ChIPs)
Growth protocol Standard conditions were used to produce logarithmically growing cultures in rich media (YEA) for H3K9me2 and Psc3-GFP and minimal medium PMG for Rec8-GFP. Cultures were grown 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) 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 stage: log growing cells
genotype/variation: dcr1d cells
fraction: whole-cell extract
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 30˚C. Prior fixation cells were incubated at 18˚C for 2h (Psc3 and Rec8 ChIPs)
Growth protocol Standard conditions were used to produce logarithmically growing cultures in rich media (YEA) for H3K9me2 and Psc3-GFP and minimal medium PMG for Rec8-GFP. Cultures were grown 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) or GFP antibody (Abcam, ab290). 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-v1_95_May07 or ChIP-v1_10_Apr08 protocol). Signal was normalized by combined rank consistency filtering with LOWES intensity normalization.
