Anchor-Based Bisulfite Sequencing (Ben Delatte)

In this episode of the Epigenetics Podcast, we caught up with Ben Delatte Research Scientist at Active Motif to talk about his work on Anchor Based Bisulfite Sequencing.

Whole Genome Bisulfite Sequencing (WGBS) is the current standard for DNA methylation profiling. However, this approach is costly as it requires sequencing coverage over the entire genome. Here we introduce Anchor-Based Bisulfite Sequencing (ABBS). ABBS captures accurate DNA methylation information in Escherichia coli and mammals, while requiring up to 10 times fewer sequencing reads than WGBS. ABBS interrogates the entire genome and is not restricted to the CpG islands assayed by methods like Reduced Representation Bisulfite Sequencing (RRBS). The ABBS protocol is simple and can be performed in a single day.
