Over the past few years, DNA methylation technologies and our knowledge of DNA methylation patterns have been advancing at a breathtaking pace. Due to this fact, DNA Methylation: Methods and Protocols, Second Edition completely revises, updates, and expands upon the popular first edition with the most current novel techniques, easier to use and more refined by the tested experience of leading experts. This revision reflects contemporary study of the subject: the analysis of gene-specific DNA methylation patterns has been complemented by genome-wide approaches, and epigenomics takes a central place. Written in the highly successful Methods in Molecular Biology series format, the chapters in this volume present brief introductions to the topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes which highlight tips on troubleshooting.
