摘要: Abstract Chromatin immunoprecipitation (ChIP) is used to map the interaction between proteins and DNA at a specific genomic locus in living cell. The protein-DNA complexes are stabilized already vivo by reversible crosslinking sheared sonication or enzymatic digestion into fragments suitable for subsequent step. Antibodies recognizing chromatin-linked proteins, transcription factors, artificial tags, protein modifications then pull down DNA-protein containing target. After reversal of crosslinks purification locus-specific quantitative PCR determine amount that was associated with target given time point experimental condition. quantification can be carried out several regions multiple qPCRs genome-wide scale massive parallel sequencing (ChIP-Seq).
