title: GSM4139496: donor22.h3k27ac_notx.rep2; Homo sapiens; ChIP-Seq
library_construction_protocol: For ChIP-seq, Cells were fixed with formaldehyde, lysates were sonicated, and complexes precipitated with antibody. For RNA-seq, RNA was extracted using the the Quick-RNA Micro Prep kit from ZymoResearch and poly-A selected. For ATAC-seq, nuclei were extracted with nuclear isolation buffer and DNA was size-selected for 125-175 bp fragments on a TBE gel For RNA-seq, cDNA was synthesized using the SuperScript III system from Invitrogen, followed by second strand synthesis, ds End Repair and UDG treatment to recover strand-specific libraries. Libraries were barcoded with BioO Nextflex adapters and amplified prior to sequencing. ChIP-seq libraries were synthesized similarly omiting the UDG treatment. ATAC-seq libraries were extracted from TBE gel, amplified, and sequenced.
