GSM2830295: aSTAT4_STAT4WT_STIM_1_INPUT; Mus musculus; ChIP-Seq
Protein was cross-linked to DNA with 0.75% formaldehyde. Clarified supernatant from sonicated nuclei were applied to antibody-bound beads. After de-crosslinking and elution, DNA was isolated using Qiagen Gel Extraction Kit. Input samples were clarified supernatant that were not applied to antibody-bound beads. Immunoprecipitated DNA was quantified by Picogreen and size was evaluated on a HighSense BioAnalyzer chip. When possible, fragments between 100 and 600 bp were size selected and Illumina Hiseq libraries were prepared using the Kapa DNA library preparation chemistry (Kapa Biosystems) using 12-15 cycles of PCR. Adaptors were diluted 1/10 or  1/50 depending on the starting amount of material available. Barcoded libraries were run on Hiseq 2500 1T in a 50bp/50bp Paired end run, using the TruSeq SBS Kit v3 (Illumina). An average of 57 million paired reads were generated per sample.
