Chromatin Immunoprecipitation: A technique for identifying specific DNA sequences that are bound, in vivo, to proteins of interest. It involves formaldehyde fixation of Chromatin to crosslink the Dna-binding proteins to the DNA. After shearing the DNA into small fragments, specific DNA-protein complexes are isolated by immunoprecipitation with protein-specific Antibodies. Then, the DNA isolated from the complex can be identified by Pcr amplification and sequencing.

Chromatin Immunoprecipitation

JoVE 5551

Histones are proteins that help organize DNA in eukaryotic nuclei by serving as “scaffolds” around which DNA can be wrapped, forming a complex called “chromatin”. These proteins can be modified through the addition of chemical groups, and these changes affect gene expression. Researchers use a technique called chromatin immunoprecipitation (ChIP) to better understand which DNA regions associate with specific histone modifications or other gene regulatory proteins. Antibodies are used to isolate the protein of interest, and the bound DNA is extracted for analysis. Here, JoVE presents the principles behind ChIP, discussing specific histone modifications and their relationship to gene expression and DNA organization. We then review how to perform a ChIP protocol, and explore the ways scientists are currently using this technique.
