| Channel 1 |
| Source name |
K27 ChIP from brain [ChIPped DNA]
|
| Organism |
Mus musculus |
| Characteristics |
tissue: Embryonic brain
age: E13.5
antibody: H3K27me3 (17-622, Millipore)
|
| Growth protocol |
Embryonic brain dissection / standard ES cell growth conditions
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Forebrains were dissected from E13.5 mouse embryos, fixed in 1% formaldehyde for 15 minutes at room temperature, washed three times with cold phosphate buffer solution (PBS) and stored at -80°C. One forebrain was used for each experiment. ChIP was performed according to (Lee et al., 2006) using 2 μg of anti-H3K4me3 (ab8580, Abcam), H3K27me3 (17-622, Millipore), 4μg Suz12 (ab12073, abcam) and 4μg Ring1B (39663, Active Motif) and EZview Red protein G/A Affinity Gel (Sigma). Immunoprecipitated and whole cell extract DNA (input) were treated with RNAseA, proteinase K and purified by two rounds of extraction with phenol/chloroform/isoamyl alcohol. ChIP and input DNA were amplified using ligation-mediated PCR (Lee et al. 2006)

| Description |
Sonicated genomic DNA
Sample name: del(1-13)d11lac
|
| Data processing |
Array data were quantile normalized with input replicate groups and scaled to medial feature intensity of 500 using TAS software (Affymetrix, www.affymetrix.com). For each genomic position, a data set was generated consisting of all (PM-MM) pairs mapping within a sliding window of 250 bp. Exported text file was submitted to an in house algorithm including setting probes mapping within the deletions to 0 before applying a running mean approach with a higher pnderation for significant pvalues.
