Sample GSM5719148 Query DataSets for GSM5719148
Status Public on Aug 04, 2022
Title Ku70_Veh_exp3
Sample type SRA
 
Source name MCF7 cells
Organism Homo sapiens
Characteristics cell line: MCF7
cell type: human breast cancer cells
treatment: Veh
antibody: Bethyl A302-624A (Lot#A302-624A-1)
Treatment protocol For hormone treatments, cells were incubated at 37°C and 5% CO2 for at least 3 days in phenol red-free DMEM (GIBCO/Invitrogen) supplemented with 5% charcoal dextran-stripped FBS (GIBCO/Invitrogen). 17-β-Estradiol (E2; Steraloids, Inc.) was added to a final concentration of 100 nM. TNFalpha(R&D systems) was added to a final concentration of 20 ng/ml. 5α-dihydrotestosterone (DHT, Sigma) was added to a final concentration of 100 nM. The ethanol (EtOH) vehicle control was 0.05% in all samples.
Growth protocol MCF7 cells were maintained at 37°C and 5% CO2 in Dulbecco's modified Eagle's medium (DMEM, GIBCO/Invitrogen), supplemented with 10% fetal bovine serum (FBS, GIBCO/Invitrogen). LNCAP cells were maintained at 37°C and 5% CO2 in Advanced RPMI 1640 medium (GIBCO/Invitrogen), supplemented with 10% fetal bovine serum (FBS, GIBCO/Invitrogen).
Extracted molecule genomic DNA
Extraction protocol Cells were cross-linked with 1% formaldehyde at room temperature for 10 min. And then the cross-linking was quenched with 0.125M glycine for 5 min. Chromatin was fragmented using a Bioruptor® Pico (Diagenode) for 10 min at high power, with an interval of 30 s between pulses to get around 200bp fragments and precleared using 20 μl Protein G Dynabeads (Life Technologies, Cat# 10009D). Subsequently, the soluble chromatin was incubated with 2-5 μg antibodies at 4°C overnight. Immunoprecipitated complexes were collected using 30 μl Protein G Dynabeads, which have been saturated with PBS/1% BSA over night at 4°C, per reaction. For all ChIPs, after de-crosslinking overnight at 65°C, final ChIP DNA was extracted and purified using QIAquick spin columns (QIAGEN).
The libraries were constructed following Illumina’s Chip-Seq Sample prep kit.
