Instrument: Illumina NovaSeq 6000
Strategy: ChIP-Seq
Source: GENOMIC
Selection: ChIP
Layout: SINGLE
Construction protocol: After fixation, cells were lysed and sonication with a Bioruptor Plus sonication device (Diagenode). Sonication was conducted for 25 cycles, with 30 sec on/off at high intensity. ChIP was performed by incubating the sonicated sample with either Rpb1 NTD (D8L4Y) Rabbit mAb #14958 or Acetyl-Histone H3 (Lys27) (D5E4) XP Rabbit mAb #8173 (Cell Signaling Technologies) and the protein A/G agarose beads. Beads were washed and eluted in 200μl of elution buffer (50 mM Tris-HCl at pH 8.0, 10 mM EDTA, 1.0% SDS). The eluates were de-cross-linked and the DNA purified using the Qiagen PCR purification kit. Libraries were prepared with the Illumina Chip-SEQ Kit multiplexed with IDT unique dual index barcodes. Library quality control was assessed using Bioanalyzer High Sensitivity DNA Analysis kit (Agilent) and sequenced on an Illumina NovaSEQ6000 (100bp paired-end reads).
