Personally I think "DNA Repair Protocol: Eukaryotic Systems" is a great academic book based on my over ten years of research experiences in Genetic Toxicology. This book provides detailed, step-by-step instructions for studying manifold aspects of the eukaryotic responses to genotoxic damage, including a lot of useful tips in handling all kinds of DNA repair experiments. Compared with Friedberg's textbook "DNA Repair and Mutagenesis", which comprehensively covers all fundamental knowledge about DNA damage, mutagenesis and DNA repair, this book focused on detailed experimental protocols and new techniques, plus a wonderful and concise introduction and explanation of each methods. In my opinion, this book refreshments my background knowledge, gives me an overview of recent progress in new methods and techniques, and ignites some new ideas to pursue further studies in this active field. Taken together, I think this is an essential handbook for professors and scientists in DNA damage and repair field and other related fields.
