title: GSM4256116: 2063A_root_H3K9me2_rep1; Brassica napus; ChIP-Seq
library_construction_protocol: Lysates were clarified from sonicated nuclei and protein-DNA complexes were isolated with antibody. ChIP-DNA was extracted with phenol:chloroform:isoamyl alcohol (Sigma–Aldrich, P3803), precipitated with ethanol, and resuspended in TE buffer. ChIP DNA libraries were prepared using an NEBNext® Ultra™ II DNA library prep kit for Illumina® (New England BioLabs, E7645). Briefly, ChIP DNA was end-repaired, ligated with an adaptor, and followed by 6–10 cycles of PCR amplification, per the manufacturer's guidelines. Next, library fragments of 250–650 bp were selected using AMPure XP beads (Beckman, A63881). Finally, the DNA fragments were sequenced using an Illumina HiSeq X Ten system (paired-end 150-bp reads).
