Chromatin immunoprecipitation followed by sequencing (ChIP-Seq) is a well-established method for identifying binding sites for DNA-binding proteins. This method involves (1) cross-linkage of DNA binding proteins to DNA, (2) DNA shearing, (3) immunoprecipitation of DNA fragments bound by a protein of interest, and (4) sequencing of precipitated DNA fragments. Resulting sequencing reads are aligned to the corresponding genome, and genome areas bound by the protein of interest are expected to…

Principle and Protocol of Chromatin Immunoprecipitation (ChIP)
Introduction: 1. Applications of ChIP: (1) Histone modifying enzyme antibody as “biomarkers”; (2) Analysis of transcriptional regulation; (3) Drug development research; (4) Analysis of DNA damage and apoptosis. 2. Details: The eukaryotic genomic DNA exists in the form of chromatin. Therefore, the study of interactions between protein and DNA in chromatin environment is the basic way to clarify the mechanism of gene expression in eukaryotes. Chromatin immunoprecipitation (ChIP) is currently…
