Abstract

Chromatin immunoprecipitation (ChIP) is a method used to examine the genomic localization of a target of interest (e.g., proteins, protein posttranslational modifications, or DNA elements). As ChIP provides a snapshot of in vivo DNA-protein interactions, it lends insight to the mechanisms of gene expression and genome regulation. This chapter provides a detailed protocol focused on native-ChIP (N-ChIP), a robust approach to profile stable DNA-protein interactions. We also describe best practices for ChIP , including defined controls to ensure specific and efficient target enrichment and methods for data normalization.
