| Title |
H3K9me2 ChIP in mmi1d cells |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
H3K9me2 ChIP DNA
|
| Organism |
Schizosaccharomyces pombe |
| Characteristics |
growth stage: log growing cells
genotype/variation: mmi1d cells
antibody: H3K9me2
|
| 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: mmi1d 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)

|
| 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.
