Chromatin Immunoprecipitation from Mouse Embryonic Tissue or Adherent Cells in Culture, Followed by Next-Generation Sequencing.

Chromatin immunoprecipitation (ChIP) is considered the method of choice for characterizing interactions between a protein of interest and specific genomic regions. It is of paramount importance in gene-regulation studies, as it can be used to map the target regions of sequence-specific transcription factors and cofactors, or histone marks that characterize distinct chromatin states. ChIP can be used directly to probe interactions with candidate regions (ChIP-PCR), or coupled to Next-Generation Sequencing (ChIP-seq) to generate genome-wide information. This chapter describes a protocol for performing ChIP and ChIP-seq of transcription factors, starting either from mouse embryonic tissue or adherent cells in culture.
