show Abstracthide AbstractChIP-seq analysis was performed in Multiple Myeloma cell lines to analyze acetylation of histone H3K27ac. Overall design: Daudi, RAJI, H929, JJN3, KMS11, KMS12, KMS28BM, RPMI8226, U266 and NP (normal plasma cell) were crosslinked with formaldehyde for 10 min. DNA was enriched by chromatin-immunoprecipitation (ChIP) and analyzed by Illumina Hiseq 4000. A sample of whole cell extract (WCE) was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against histone H3 lysine 27 acetylation (H3K27Ac: Abcam, ab4729).
