PubReading [248] - Third Generation Sequencing of Epigenetic DNA - B. Searle, M. Müller, T. Carell and A. Kellett

The discovery of epigenetic bases has revolutionised the understanding of disease and development. Among the most studied epigenetic marks are cytosines covalently modified at the 5 position. In order to gain insight into their biological significance, the ability to determine their spatiotemporal distribution within the genome is essential. Techniques for sequencing on ‘Next Generation’ platforms often involve harsh chemical treatments leading to sample degradation. Third generation sequencing promises to further revolutionise the field by providing long reads, enabling coverage of highly repetitive regions of the genome or structural variants considered unmappable by next generation sequencing technology. While the ability of third generation platforms to directly detect epigenetic modification ...
