Chromatin immunoprecipitation (ChIP) is a powerful tool to study protein-DNA interaction and is widely used in many fields to study proteins associated with chromatin, such as histone and its isoforms and transcription factors, across a defined DNA domain. Here, we show the step-by-step methods currently used in our lab to immunoprecipitate the formaldehyde crosslinked chromatin and further analyze the immuprecipitated DNA by semiquantitative PCR.
