ChIP Assays and Components from IMGENEX: QuikChIP

Chromatin Immunoprecipitation Kits & Reagents

Chromatin Immunoprecipitation (ChIP) is a powerful method used to identify regions of the genome associated with specific proteins. These associations are crucial for vital cellular functions including gene transcription, DNA replication and recombination, repair, segregation, chromosomal stability, cell cycle progression, and epigenetic silencing. The ChIP assay has been used to study both histones and non-histone proteins, such as transcription factors, within the context of the cell. Transcription factors and other DNA binding proteins have a weaker affinity than histones, which generally are tightly associated within the chromatin complex. To avoid dissociation of non-histone proteins from the chromatin binding site, it is necessary to incorporate a cross-link step such as formaldehyde to cross-link proteins to DNA. After cross-linking occurs, the chromatin are released from the nuclei and sheared into 200-1000bp fragments. The chromatin are then immunoprecipitated with specific antibodies. DNA sequences cross-linked to the protein of interest co-precipitate as part of the chromatin complex. The DNA/ chromatin/antibody complex is then isolated using Protein G agarose. After reverse cross-linking, the associated DNA is released from the complex and is ready for analysis.

Tools for Effective Chromatin Immunoprecipitation

The QuikChIP™ difference

The principle of the ChIP assay is simple: selective enrichment of a chromatin fraction containing a specific antigen. However, the process can be technically challenging. Depending on the protein of interest and starting material, appropriate antibodies may be difficult to come by. Not only must the antibody be able to bind to the protein in its native state, the epitope it recognizes can't be cloaked by the DNA. Beyond the challenge of finding an acceptable antibody, the outcome of your ChIP experiment also depends on the correct formulation of several different reagents and buffers. It is with these technical challenges in mind that IMGENEX developed QuikChIP™ kits and reagents. These products include ready-to-use kits containing critical buffers and inhibitory formulations, ChIP certified antibodies, DNA purification kits, and pre-sheared DNA from cell lysates. Each IMGENEX QuikChIP™ kit or reagent has been carefully developed and tested with ease, simplicity, and quality results in mind.
