Snap-frozen mouse liver (100 mg) from wild type mice was used to prepare chromatin. Rabbit polyclonal antibodies specific to Setdb1 (Proteintech, 11231-1-AP), Kap1 (Abcam, ab10483), and anti-acetyl-histone-H3 specific to Lys-14 (Millipore, 07-353) were used for immunoprecipitation. Libraries were prepared according to Illumina's instructions. Briefly, DNAs were blunted with a combination of T4 DNA polymerase, Klenow polymerase, and T4 PNK, then a single 3′-end “A” base was added using Klenow exo (3′-to-5′ exo minus). multiplex adapters were then ligated to the ends of the modified DNA. After adapter ligation DNA was PCR amplified with Broad custom primers for 16 cycles and library fragments of ~280 bp (~150-bp mononucleosome insert plus ~130-bp adaptor and PCR primer sequences) were isolated using Pippin Prep agarose gel. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on Illumina NextSeq 500 (Sedb1 & Kap1) and Illumina Hiseq 2500 (H3K14ac) following the manufacturer's protocols.
