ChIP-Seq, short for Chromatin immunoprecipitation sequencing, is a next-generation based sequencing method to comprehensively study the interaction between proteins and DNA. It takes advantage of the specificity of the antigenic antibody response to provide a fidelity reflection of the binding of protein factors to genomic DNA in vivo.
In recent years, due to the continuous development and refinement of ChIP-Seq its application has evolved from the study of interactions between target proteins and known target sequences to the study of interactions between target proteins and unknown sequences throughout the genome; from studying the interaction of a target protein with DNA to the interaction of two proteins co-associated with DNA; from studying the modification of histones in promoter regions to protein complexes bound to DNA sequences. And ChIP-Seq can be widely used in transcription factor binding sites (TFBSs) and histone modification studies. This technique uses reagents such as formaldehyde to cross-link and immobilize protein-DNA complexes in cells, lyses and ultrasonic processing cells, and immunoprecipitates them with antibodies specific to the target protein (or labeled antibodies) to obtain the target protein-DNA complexes. High-throughput sequencing of the DNA in the cross-linked isolated complexes allows the identification of DNA sequences that may interact with the target protein.
