Title |
H3-FLAG ChIP in wild-type cells |
Sample type |
genomic |
|
|
Channel 1 |
Source name |
HU blocked cells_immunoprecipitated DNA
|
Organism |
Schizosaccharomyces pombe |
Characteristics |
genotype: wild-type
|
Treatment protocol |
Mid-log phase cells grown in minimal media supplemented with 8% glucose were treated with 15mM HU for 4h. Cells were switched to minimal media supplemented with 4% sucrose and 15mM HU for 2h for induction of H3-FLAG expression. Cells were fixed in 1% formaldehyde at 30˚C.
|
Growth protocol |
Cells were grown in minimal media 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 anti-FLAG M2 agarose (Sigma, A2220). Immunoprecipitated DNA was recovered by incubation with protein A or 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).

Source name |
HU blocked cells_whole-cell extract DNA
|
Organism |
Schizosaccharomyces pombe |
Characteristics |
genotpye: wild-type
|

|
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_107_Sep09 or ChIP_1200_Jun14 protocol). Signal was normalized by combined rank consistency filtering with LOWES intensity normalization. Background signal was estimated as a median processed signal of 152 oligonucleotides with no homology to S. pombe genome.
