GSM4909114: FOXA1 ChIP-seq in P5091 treated LNCaP cells_rep #1; Homo sapiens; ChIP-Seq
Chromatin in nuclear fraction were sheared to 200-500bp using an Covaris M220 Focused-ultrasonicator, Lysates were clarified from sonicated nuclei and protein-DNA complexes were immunoprecipitated using the indicated antibody. DNA was then reverse crosslinked from protein and purified.  ChIP-seq libraries were prepared from 3-5ng ChIPped DNA by using NEBNext® Ultra™ II DNA Library Prep Kit (NEB, E7645S), according to the manufacturer's instructions. Postamplification libraries were size selected at 250–450 bp in length using Agencourt AMPure XP beads from Beckman Coulter and were quantified using the Library Quantification Kit from Illiumina (Kapa Biosystems, KK4603). Libraries were pooled to a final concentration of 10nM and sequenced single-end using the Illumina HiSeq 4000.
