Illumina sequencing of Mouse ES_Tcfcp2I1 genomic fragment library
           Whole cell extracts were sonicated to solubilize the chromatin. The chromatin extracts containing DNA fragments with an average size of 500 bp were immunoprecipitated using different antibodies. ChIP-enriched DNA from multiple ChIP experiments was pooled and quantified using PicoGreen dsDNA quantitation kit (Invitrogen). The ChIP-enriched DNA was processed for Solexa sequencing using ChIP-Seq Sample Prep Kit (Illumina).
