"WebUnlike DNA-protein crosslinking which is done with formaldehyde, CLIP uses ultraviolet (UV) light. Unlike formaldehyde, UV crosslinking is irreversible. UV crosslinks are also more specific and only link proteins to RNAs that are in very close proximity. Further, UV crosslinks do not form between two proteins (Brimacombe et al., 1988).
