Sample GSM4725504 Query DataSets for GSM4725504
Status Public on Dec 22, 2020
Title Rec12-201-6xHis-2xFLAG ChIP in pat1-114, rad50S, GFP-Pir1 cells
Sample type genomic
 
Channel 1
Source name immunoprecipitated Rc12-DNA linkages
Organism Schizosaccharomyces pombe
Characteristics growth temperature: cells growing in 34˚C
genotype: pat1-114 rad50S cells expressing GFP-Pir1 and Rec12-201-6xHis-2xFLAG
Treatment protocol Exponentially growing cells were fixed in 3% paraformaldehyde at 30˚C. For GFP and c-MYC ChIPs, fixed cultures were subjected to additional crosslinking with 10 mM DMA for 45 min at room temperature. For Rec12-DNA linkages ChIPs, induced meiotic cells were collected without paraformaldehyde or DMA treatment.
Growth protocol For H3K9me2 and Pir1 ChIP, standard conditions were used to produce logarithmically growing cultures in rich media (YEA). Cultures were grown at 30˚C. For Rec12-DNA linkages ChIP, pat1-114 cells were nitrogen starved with EMM-N at 26˚C for 6 h to arrest the cells in G1. The starved cultures were centrifuged and resuspended in EMM medium in 34˚C to induce synchronized meiosis for 4.5 h.
Extracted molecule genomic DNA
Extraction protocol 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. The Rec12-DNA linkages were recovered by incubation with anti-FLAG-agarose (A2220).
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

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-FLAG-agarose (A2220) 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 LOWESS intensity normalization.
