Instrument: Illumina HiSeq 2500
Strategy: ChIP-Seq
Source: GENOMIC
Selection: ChIP
Layout: SINGLE
Construction protocol: Cell lysis and nuclei isolation was performed using the TruChIP Chromatin Shearing Kit High Cell SDS (Covaris). Nuclei were sonicated using the S220 Ultrasonicator (Covaris) in order to obtain chromatin fragments of 200-500bp. ChIP was performed using anti-BCL6 (N3, Santa Cruz) or the anti-FOXO1 (Abcam, ab39670) antibodies. ChIP DNA was isolated by the MinElute DNA isolation kit (Qiagen). ChIP-seq libraries were constructed starting from 4ug of ChIP or Input DNA as reported in Blecher-Gonen et al., 2013, Nature protocol. Libraries were quantified using the KAPA SYBR FAST Universal qPCR Kit (KAPA Biosystems), normalized to 10nM, pooled and sequenced in an Illumina HiSeq 2500 instrument as single-end 100 bp reads, obtaining on average 25x10^6 reads/sample.
