CSE4_ChIP-seq_IP  reads
4ng of  ChIP-DNA was used for library construction, following the instructions from  Illumina (DNA Library Prep Kit, #E7645S). In brief, the fragmented DNA was  subjected to end repair followed by A-tailing and adapter ligation.Illumina  index adapter primers were used to PCR amplification. The amplified product  was purified using Ampure beads. The library was quantitated and the quality  was checked using Agilent 7500 DNA Kit.
