Protein crosslinking protocol

WebbDNA-protein crosslinks (DPCs) are a specific type of DNA lesion consisting of a protein covalently and irreversibly bound to DNA, which arise after exposure to physical and chemical crosslinking agents. DPCs can be bulky and thereby pose a barrier to DNA replication and transcription.

WebbRegulation of histone H3 lysine 4 and 79 methylation by histone H2B lysine 123 monoubiquitination is an evolutionarily conserved trans-histone crosstalk mechanism, which demonstrates a functional role for histone ubiquitination within the cell. WebbWhen targeting proteins that bind weakly to DNA, we highly recommend a crosslinking ChIP (X-ChIP) protocol. X-ChIP may be performed with UV light, formaldehyde, or other chemical cross-linkers. Cell lysis facilitates the release of the cell nuclei and eliminates components of the cytoplasm that can contribute to background signals.
