title: GSM2445937: dmrc1_HU_BrdUIP; Schizosaccharomyces pombe; ChIP-Seq
library_construction_protocol: Protocol 1: The cell wall was disrupted by zirconia beads and multi-beads shocker (Yasui Kikai Co.). Lysates were prepared by sonication and clarified by centrifugation. Protein and DNA complexes were immuno-precipitated by antibody conjugated with Protein G Dynabeads. Protocol 2: BrdU-incorporated genomic DNA was purified by Qiagen Genomic-tip and genomic buffer set. Purified genomic DNA was sheared by sonication. The fragmented DNA was heat-denatured and BrdU-substituted DNA was immuno-precipitated by Anti-BrdU antibody conjugated with anti-IgG1a-dynabeads. ChIP, BrdUIP, and Input DNA was sheared to around 150bp by S220 Focused-ultrasonicators (COVARIS, INC.). The fragmented DNA were end-repaired, ligated to sequencing adapters and amplified according to the protocol of NEBNext® ChIP-Seq Library Prep Master Mix Set and NEBNext Multiplex Oligos for Illumina (New England Biolabs) to prepare library. The size and concentration of libraries were checked by Bioanalyzer 2000 and real-time PCR using KAPA Library Quantification Kits, respectively.
