Anchor-Based Bisulfite Sequencing determines genome-wide DNA methylation. Anchor-Based Bisulfite Sequencing determines genome-wide DNA methylation

Whole Genome Bisulfite Sequencing (WGBS) is the current standard for DNA methylation profiling; however, WGBS is costly as it requires sequencing coverage over the entire genome. Here we introduce Anchor-Based Bisulfite Sequencing (ABBS). We show that ABBS captures accurate DNA methylation information in Escherichia coli and mammalian cells, while requiring approximately 20 times fewer sequencing reads than WGBS. The ABBS protocol is simple and can be performed in a single day. Overall design: WGBS and ABBS on E. coli and K562 cells
