Mutant p53 may activate target genes through the interaction of transcription factors or through histone modifications. Chromatin immunoprecipitation (ChIP) is a method commonly used to study these types of protein interactions. In order to generate a list of target genes that may be activated through this mechanism, ChIP sequencing may be used. ChIP sequencing involves the mass parallel sequencing of ChIP DNA fragments. We describe a method by which to prepare chromatin immunoprecipitation sequencing libraries and how to analyze sequencing data. In this procedure, prepared libraries have been sent to a core facility. The results have been verified using quantitative PCR.
