Sample GSM2461325 Query DataSets for GSM2461325
Status Public on Aug 08, 2017
Title 3h LPS RelA ChIP
Sample type SRA
 
Source name 3h LPS RelA
Organism Mus musculus
Characteristics strain: C57BL/6J
cell type: Bone marrow derived macrophages
treatment: 3h LPS RelA
chip antibody: RelA (Ab7970, Abcam) and Dynabeads Protein A
Treatment protocol Primary macrophages derived from bone marrow were stimulated with lipopolysaccharide and/or Dex for the indicated number of hours.
Extracted molecule genomic DNA
Extraction protocol For RelA ChIP, BMDMs were subject to crosslinking with 1% formaldehyde for 10 minutes at room temperature. For GR ChIP, we used a dual crosslinking method (Uhlenhaut et al., 2013) to detect both tethered and directly bound chromatin. BMDMs were subject to crosslinking with 2mM disuccinimidyl glutarate (DSG) for 30 min followed by 1% formaldehyde for 10 min at room temperature. After crosslinking, chromatin was isolated from about 4 × 10^7 cells, which allows 2 to 3 different immunoprecipitations per sample at a time, and then processed as follows. The lysis buffer to shear the chromatin contained 0.5% SDS, 10 mM EDTA (pH 8), 50 mM tris-HCl (pH 8), and proteinase inhibitor cocktail. Sonication was performed to shear the chromatin to generate DNA fragments with a size range of 400 to 500 base pairs. The sheared chromatin samples were diluted 1:5 in dilution buffer (0.01% SDS, 1.1% Triton-X, 1.2 mM EDTA (pH 8), 20 mM tris-HCl (pH 8), 167 mM NaCl, and proteinase inhibitor cocktail). For each ChIP, 200 µg chromatin DNA was precipitated with antibody coated bead complexes (Dynabeads Protein A for RelA ChIP; anti-IgG paramagnetic beads for GR ChIP, Invitrogen).
sequencing libraries were generated using Illumina TruSeq V3 protocol and subject to 51 bp single-end sequencing on Illumina HiSeq2000.
