Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody for ChIP-seq. RNA was harvested using Trizol reagent and mRNA isolated with polydT dynabeads. Strand-specific protocol was used with 5 ug of mRNA for the construction of the library. Libraries were prepared according to Illumina's instructions. 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 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 a controlled (qPCR estimated) cycles and library fragments of ~220 bp were band isolated from an agarose gel. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer (GA), GAIIx, or Hiseq2000) following the manufacturer's protocols.
