title: GSM1430424: iPSC OSK9; Mus musculus; ChIP-Seq
library_construction_protocol: ChIP DNA samples were obtained with Native ChIP protocol; briefly, chromatin were fractionated and then  subject to Mnase digestion to generate mononucleosomes. Then the mononucleosome fraction was extracted with high salt buffer and H2A.X-containing nucleosomes were isolated and enriched with anti-H2A.X antibodies. Libraries were prepared according to Illumina's standard protocol, with instructions accompanying the DNA Sample Kit
