title: GSM1940054: Gata1 ChIPseq; Mus musculus; ChIP-Seq
library_construction_protocol: Approximately 7x106 FACS-sorted day 5 EB cells per ChIP were cross-linked using formaldehyde to a final concentration of 1%. As samples were pooled from several sorts, isolated nuclei were frozen on dry ice cold isopropanol and stored at -80°C. During the immunoprecipitation step, 4 μl recombinant histone 2B (New England Biolabs) and 1 μl of mouse RNA (Qiagen; diluted 1/5 in IP dilution buffer) were added as carriers, followed by 7 μg of primary antibody Sequencing libraries were prepared using the TruSeq Kit (Illumina) for high throughput sequencing on an Illumina HiSeq 2500, according to manufacturer’s instructions, with size selection for fragments of 150-400 bp.
