Our starting point is TrueMethylTM oxidative bisulfite sequencing (oxBS-Seq), a novel technology that pioneers quantitative, single-base resolution sequencing of the modified bases hydroxymethyl cytosine (5-hmC) and methylcytosine (5-mC). TrueMethyl enables analysis of the DNA methylome with unprecdented accuracy and opens new avenues for basic research, pharmaceutical discovery and diagnostics.
Recent studies have shown that at some sites in the genome the level of 5-hmC can be comparable to the level of 5-mC, emphasizing the importance of identifying these variants accurately. However, traditional bisulfite sequencing cannot discriminate between 5-hmC and 5-mC.
