| Title |
ChIP-seq_H3K27ac_ILC2_asthma |
| Sample type |
SRA |
| |
|
| Source name |
Lung
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6
genotype: WT
tissue: Lung
cell type: ILC2
condition: asthma
chip antibody: H3K27ac (abcam, ab4729)
|
| Treatment protocol |
Mice were administered with 10 µg of HDM at day -6 and day 0-4. Cells were harvested at day 0 for control and day 6 for asthma.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Lungs were cut into small pieces and digested in RPMI containing collagenase A and Dnase I using gentleMACS Dissociator and then passed through 70 µm filter. Lung ILC2s and CD4 T cells were sorted by SONY SH800 following crosslink with 1% formaldehyde.
Sonicated samples were immunoprecipitated using H3K27ac antibody (ab4729, Abcam) and Dynabeads Protein A. Chromatin-DNA complexes were washed seven times and reverse-croslinked by overnight incubation at 65 ˚C. DNA fragments were harvested with phenol-chloroform extraction followed by ethanol precipitation. ChIP-seq libraries were prepared with ThruPLEX DNA-seq kit.
