Instrument: Illumina HiSeq 2500
Strategy: ChIP-Seq
Source: GENOMIC
Selection: ChIP
Layout: PAIRED
Construction protocol: ChIP was performed as detailed by Sailaja et al PNAS 109:E3687-3695 2012 Paired end libraries were constructed using standard Illumina protocols, with some modifications. Agencourt AMPure XP (Beckman Coulter) at 0.8x ratio were used to size select out adapter dimers. The Illumina Phusion enzyme was replaced by Kapa HiFi HotStart ready mix (Kapa Biosystems). An Invitrogen SizeSelect R-gel system (Life Technologies) was used to size select following PCR amplification. Sequenced was performed on an Illumina HiSeq 2500 at The Crick Institute, London.
