title: GSM2175782: H3K27Ac ChIP-seq MCF10A rep2; Homo sapiens; ChIP-Seq
library_construction_protocol: For RNA-seq, RNA was extracted using Trizol reagent (15596-026) (Life technologies, Carlsbad, CA) following its protocol. For ChIP-seq, cells were crosslinked using 1% formaldehyde andl lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody. For FAIRE-seq, nuclei were extracted after the crosslinking step (1% formaldehyde in PBS) of intact cells, followed by re-suspension in SDS lysis buffer before sonication. FAIRE DNA samples were purified by phenol/chloroform extraction. Input DNA was also purified by phenol/chloroform extraction after the crosslinking was reversed. RNA-seq libraries were made using KAPA Stranded mRNA-Seq Kit with KAPA mRNA Capture Beads (KK8420) (Kapa Biosystems, Woburn, MA). ChIP-seq: Libraries were barcoded (NEXTflex™ DNA Barcodes) (Bio Scientific, Austin, TX). FAIRE-seq: Libraries were prepared according to Illumina's instructions (http://epigenome.usc.edu/services/nextgen/making_libraries.html)
