Lysates were clarified from sonicated nuclei and FH-Foxd3-DNA complexes were isolated with antibodies against HA or Flag. Lysates were clarified from sonicated nuclei and ChIP-DNA complexes were isolated with antibody. Libraries were prepared according to Illumina's instructions accompanying the DNA Sample Kit (Part# 0801-0303). 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 size selected on agarose gel from 200-700 bp. Then isolated DNA was PCR amplified with Illumina primers for 18 cycles. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols.
