WebDec 6, 2024 · The basic protocol is still similar to one developed in the 1980s, involving crosslinking proteins to DNA with formaldehyde and then fragmenting the DNA. A DNA-interacting protein is immunoprecipitated using an antibody, the crosslinks reversed with heat, and the associated DNA analyzed. WebProtein cross-linking and the analysis of cross-linked peptides by mass spectrometry is currently receiving much attention. Not only is this approach applied to isolated complexes to provide information about spatial arrangements of proteins, but it is also increasingly applied to entire cells and their organelles. iron tbec
