| Sample type |
SRA |
| |
|
| Source name |
Primary bone marrow-derived macrophages (BMDM) from Fvb mice
|
| Organism |
Mus musculus |
| Characteristics |
cell type: BMDM cells (7th day of differentiation)
antibody: Anti-p300
antibody manufacturer: Santa Cruz
antibody catalog number: sc-585
treatment: LPS (10 ng/ml) for 2hrs
|
| Treatment protocol |
Macrophages were stimulated with lipopolysaccharide (LPS, 10 ng/ml)
|
| Growth protocol |
Bone marrow cells isolated from female Fvb mice were plated in 10 cm plates in 5ml of BM-medium (high glucose DMEM supplemented with 20% low endotoxin fetal bovine serum, 30% L929-conditioned medium, 1% glutamine, 1%, Pen/Strep, 0.5% Sodium Pyruvate, 0.1% β-mercaptoethanol). Cultures were fed with 2.5 ml of fresh medium every two days.

genomic DNA |
| Extraction protocol |
ChIP lysates were generated from 2x10^8 cells. Cells were fixed in 1% formaldehyde for 10min. Lysate was immunoprecipitated with 10ug of antibody. Antibodies were pre-bound overnight to 100ul of G protein-coupled paramagnetic beads in PBS/BSA 0.5%. Beads were then added to lysates (the preclearing step was omitted) and incubation was let to proceed overnight. Beads were washed 6 times in a modified RIPA buffer (50mM Hepes pH 7.6, 500mM LiCl, 1mM EDTA, 1% NP-40, 0.7% Na-deoxycholate) and once in TE containing 50mM NaCl. DNA was eluted in TE containing 2% SDS and crosslinks reversed by incubation overnight at 65ºC. DNA was then purified by Qiaquick columns (Qiagen) and quantified using PicoGreen (Invitrogen). ChIP DNA was prepared for Solexa 2G sequencing using a standard protocol consisting in blunting, addition of dA overhangs, ligation of Illumina adapters, selection on gel and PCR. A mixture of T4 DNA polymerase, DNA polymerase I and T4 kinase was used according to manufacturer’s instruction.

Chromatin IP against p300 2hrs post treatment

| Data processing |
Alignment: sequence reads were mapped to the mouse mm9 genome using ELAND (Illumina pipeline version 1.3). All reads that maps uniquely to the genome with two or fewer mismatches were kept.
Peaks: analyses were performed using MACS (PMID: 18798982) with a bandwith of 150bp and a p-value threshold of 10^-5. p300 and H3K4me1 ChIPs were normalized against input DNA. PU.1 ChIPs were normalized against a theoric distribution of the same number of tags.
