Formaldehyde fixed chromatin was isolated from cells and YAP1 bound chromatin was purified using YAP1 antibody using standard Chromatin IP method. Libraries were prepared using NEB reagents as described earlier (Garber et al 2012). Briefly, DNA was end-repaired using a combination of T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. After adapter ligation DNA was PCR amplified with Illumina primers for 12 cycles and library fragments of ~300-500 bp (insert plus adaptor and PCR primer sequences) were size selected by SPRI beads. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the HiSeq2000 following the manufacturer's protocols.
