| Title |
H3K4me2_2_wt |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Schizosaccharomyces pombe whole cell extract (WCE) genomic DNA
|
| Organism |
Schizosaccharomyces pombe |
| Characteristics |
Chromatin DNA isolated from paraformaldehyde cross-linked wild type Schizosaccharomyces pombe cells
|
| Treatment protocol |
Schizosaccharomyces pombe cells crosslinked with paraformaldehyde
|
| Growth protocol |
Asynchronous growing fission yeast cells at 30 C and cross-linked at 18C with paraformaldehyde for 30 minutes
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Chromatin was extracted from cross-linked cells following lysis with bead beater and sonication. After reverse cross-linked and digested with Rnase A and proteinase K, DNA was recovered by phenol/chloroform extraction and ethanol precipitation
|
| Label |
Cy3
|
| Label protocol |
WCE DNA after amplified by random priming PCR incorporating amino-allyl dUTP was covalently coupled with Cy3 mono NHS ester in 100 mM sodium bicarbonate for 1 hr at room temperature. Labeled DNA was recovered by Qiagen QIAquick PCR column
|
| |
|
| Channel 2 |
| Source name |
Schizosaccharomyces pombe chromatin immunoprecipitated DNA
|
| Organism |
Schizosaccharomyces pombe |
| Characteristics |
Chromatin DNA isolated from paraformaldehyde cross-linked wild type Schizosaccharomyces pombe cells and enriched for H3K4me2 chromatin with antibody against dimethylated histone H3 at lysine 4.
|
| Treatment protocol |
Schizosaccharomyces pombe cells crosslinked with paraformaldehyde
|
| Growth protocol |
Asynchronous growing fission yeast cells at 30 C and cross-linked with paraformaldehyde at 18C for 30 minutes
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Chromatin was extracted from cross-linked cells following lysis with bead beater and sonication. After reverse cross-linked and digested with Rnase A and proteinase K, DNA was recovered by phenol/chloroform extraction and ethanol precipitation
|
| Label |
Cy5
|
| Label protocol |
ChIP DNA after amplified by random priming PCR incorporating amino-allyl dUTP was covalently coupled with Cy5 mono NHS ester in 100 mM sodium bicarbonate for 1 hr at room temperature. Labeled DNA was recovered by Qiagen QIAquick PCR column
|
| |
|
| |
| Hybridization protocol |
500 ng of Cy3 labeled WCE DNA was mixed with 500 ng of Cy5 labeled ChIP DNA plus 50 ul Agilent 10X control targets and 250 ul of 2X Agilent Hybridization buffer
|
| Scan protocol |
Slides were scanned using Agilent scanner and image intensity data were extracted and analyzed with Agilent Feature Extraction software version 7.5
|
| Description |
Schizosaccharomyces pombe cells, H3K4me2 ChIP(chromatin immunoprecipitation)-on-chip, replicate 2
|
| Data processing |
Log ratios of ChIP over WCE were obtained by dividing normalized median Cy5 value over its corrresponding Cy3 value
