title: GSM2730573: Naa10p-ChIPseq_WT-mES; Mus musculus; ChIP-Seq
library_construction_protocol: The mES cells were fixed with 1% formaldehyde for 10 min, followed by 0.125 M glycine quenching for 5 min. Cells were lysed in 1% SDS, 10 mM EDTA and 50 mM Tris-HCl (pH 8.0) and the DNA was fragmented by sonication to approximately 150-300 bp (Bioruptor, Diagenode). Immunoprecipitation was performed with 10 μg of rabbit polyclonal Naa10p for overnight at 4 °C. Antibody-bound samples were isolated by protein G agarose beads (Active Motif), washed, eluted and reverse cross-linked. ChIPed DNA was extracted by phenol/chloroform, ethanol precipitated and quantified by Qubit assay (Invitrogen). The ChIPed DNA library for NextSeq 500 sequencing was constructed using the NEBNext DNA library Prep Master Mix Set for Illumina (New England Bio Labs) according to the manufacturer's instruction. Briefly, the ChIPed DNA was blunt ended and a dA tail was added. The DNA with dA overhangs was ligated with multiplex oligos for illumina with individual index sequences (New England Bio Labs). Adaptor-ligated DNA was amplified by PCR for 12 cycles, followed by size selection using magnetic beads (KAPA Pure Beads, KAPA Biosystem). The purified DNA was quantified by Qubit assay (Invitrogen) and qualified by Agilent Bioanalyzer.
