Web1.1 The Method. Photochemical crosslinking is a powerful method for studying all types of protein-nucleic acids interactions. In particular UV-induced crosslinking has been successfully applied to the study of protein-DNA interactions (e.g., ref. 1, see Chapters 23–26 and 43).Ultraviolet (UV) light is a zero-length crosslinking agent. WebJul 31, 2024 · DNA-crosslinks are one of the most severe types of DNA lesions. Crosslinks (CLs) can be subdivided into DNA-intrastrand CLs, DNA-interstrand CLs (ICLs) and DNA-protein crosslinks (DPCs), and arise by various exogenous and endogenous sources. If left unrepaired before the cell enters S-phase, ICLs and DPCs pose a major threat to …

WebHere we describe a versatile and high-resolution method which involves two basic steps: (1) in vivo formaldehyde cross-linking of intact cells followed by (2) selective immunoprecipitation of protein-DNA complexes with specific antibodies. This method allows for detailed analyses of protein-DNA interactions in a native chromatin environment. WebUV light is a zero-length crosslinking agent that predominantly or exclusively crosslinks proteins to nucleic acids at their contact points. It can therefore provide strong evidence for close protein-nucleic acid interactions. However, to achieve an acceptable degree of crosslinking with conventional UV light sources, exposure times ranging ...
