This volume provides detailed methods and key approaches used to mechanistically study DNA damage, as well as the factors involved in the damage response. Chapters guide readers through proteomics and biophysical approaches, analyzing protein function, quantifying DNA replication dynamics and nucleic acid base damage, as well as biochemical reconstitution of key pathways involved in DNA repair. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, DNA Damage Responses: Methods and Protocols aims to be a useful practical guide to researches to help further their study in this field.
