Sample GSM872895 Query DataSets for GSM872895
Status Public on Jul 30, 2012
Title Input DNA
Sample type SRA
 
Source name G1ME cells
Organism Mus musculus
Characteristics strain: J1
cell type: G1ME
cell line: GATA1-deficient cell line with megakaryocyte and erythrocyte differentiation potential
protocol: Cells grown in TPO supernatant (10% v/v)
retrovirus: MigR1-HA-Gata1
fraction: input
Treatment protocol Retroviral supernatant was added to the cells at 1e6 cells per ml, and the culture was centrifuged at 3200rpm for 90min. The cells were incuabted in the virus for an additional 4h, and then the virus was removed. The cells were crosslinked 48h later.
Growth protocol G1ME cells were cultured in 1% TPO supernatant (v/v)
Extracted molecule genomic DNA
Extraction protocol Isolated chromatin was sonicated and pre-cleared with isotype-matched mouse non-specific IgG. Chromatin immunprecipitation was carried out with a HA-tag antibody (Santa Crruz Biotechnology, sc-7392). The formaldehyde crosslinks were reversed by heating to 65-degrees overnight. RNA and protein were removed by treatment with RNAse A and Proteinase K, respectively, and the DNA was isolated using the Qiagen PCR Purification Kit. Libraries were prepared according to Illumina's instructions accompanying the DNA Sample Kit (Part# IP-102-1001).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer II
 
Data processing Mappable reads were aligned to mouse genome mm9 using the Illumina pipeline
Peaks were identified with MACS v1.3.7.1 (Zhang Y, 2008) using the full set of unique IP tags as the ‘treatment’ and an equally-sized, randomly sampled subset of unique input tags as the ‘control,’ with the default p-value (10-5), and an ‘mfold’ value of 15. MACS was run three times for each IP tag set, using a different random subset of input, and the base-wise intersection of the three runs was obtained using intersectBed from BEDTools (Quinlan and Hall, 2010).
