Chromatin immunoprecipitation-based analysis of gene regulatory networks operative in human embryonic stem cells.

Chromatin immunoprecipitation (ChIP) followed by microarray-based (ChIP-Chip) or next-generation sequencing-based (ChIP-Seq) analysis has been established as a powerful and widely used method to investigate DNA-protein interactions relative to a genomic location in vivo. Here, we present a ChIP-Chip protocol, which utilizes an alternative, easier amplification protocol and when using high-quality ChIP-grade antibodies, will generate enough material for hybridization or sequencing with negligible enrichment bias due to amplification.
