After immunoprecipitation of protein–DNA complexes protein–DNA cross-links are reversed and the DNA is extracted. Various methods exist to identify binding sites and determine relative occupancy of the protein of interest; these include quantitative PCR, probing microarrays or sequencing the isolated DNA (ChIP-seq). This chapter details the method of chromatin immunoprecipitation of TOP2 to the point of DNA extraction from the precipitated protein–DNA complexes.
