Chromatin immunoprecipitation (ChIP) is a common tool used to study protein-DNA interactions in c...
Cross-linking is typically achieved by using formaldehyde which forms reversible DNA-protein links. However, formaldehyde is usually not effective in cross-linking proteins that are not directly bound to the DNA. For example, inducible transcription factors or cofactors interact with DNA through protein-protein interactions, and these are not well preserved with formaldehyde. For such higher order and/or dynamic interactions such as this, other cross-linkers should be considered for efficient protein-protein stabilization. Diagenode's ChIP cross-link Gold which is used in combination with formaldehyde is an excellent choice for such higher order protein interactions.
