| Summary: | Cells possess multiple DNA repair pathways to tackle a variety of DNA lesions. Often,
DNA repair proteins function as large protein complexes. Here, we describe a protocol
to purify DNA repair protein complexes from nuclei of mammalian cells. The method
permits purification of protein complexes containing stable as well as transiently
associated proteins, which subsequently can be identified by mass spectrometry
analysis. This protocol can be applied to uncover the functions and mechanism of DNA
repair pathways. |
