Sample GSM1532606 Query DataSets for GSM1532606
Status Public on Feb 23, 2015
Title BRD4 G1E rep1
Sample type SRA
 
Source name G1E_BRD4 G1E
Organism Mus musculus
Characteristics cell type: GATA1 null erythroblasts (G1E)
gata1 transgene: none
treated with: none
chip antibody: BRD4
chip antibody vendor: Bethyl
chip antibody cat. #: A301-985A
chip antibody lot #: Lot# 1
Treatment protocol 10mM JQ1 was added to a final concentration of 250nM. 10mM E2 was added to a final concentration 100nM.
Growth protocol G1E cells were grown in IMDM +20% FBS, glutamine, penicillin/streptomycin, MTG, and Epoetin alpha in a standard tissue culture incubator at 37 degree with 5% CO2.
Extracted molecule genomic DNA
Extraction protocol Chromatin immunoprecipitation was performed as described (Kadauke et al. Cell 2012). Cells were fixed in 1% formaldehyde for 10 minutes with gentle shaking at room temperature. Sonication employed a Diagenode Bioruptor (High signal, 30 seconds on/30 seconds off, for 30 minutes). IPs were performed using protein A/G sepharose beads. Beads were washed in high salt buffer and eluted in buffer containing bicarbonate and SDS. Crosslinks were reversed by heating to 65 degrees overnight. DNA was purified on Qiagen miniprep columns.
Libraries were prepared using the protocol as outlined for Illumina's TruSeq ChIP Sample Prep Kit ( IP-202-1012), except that the libraries were size selected using Agencourt SPRIselect beads for an average size of ~300-325bp prior to PCR amplification. Library quality was assessed using the Aglient Bioanalzyer 2100 and libraries were sequenced on the Illumina HiSeq2000.
