Chromatin Immunoprecipitation-Sequencing (ChIP-seq) for Mapping of Estrogen Receptor-Chromatin Interactions in Breast Cancer.

Chromatin immunoprecipitation-sequencing (ChIP-Seq) is a powerful tool which combines the established method of ChIP with next-generation sequencing (NGS) to determine DNA-binding sites of a protein of interest on a genome-wide level, importantly, allowing for de novo discovery of binding events. Here we describe ChIP-seq using the well-established example of estrogen receptor-α mapping in the MCF7 breast cancer cell line.
