EpiGnome^™ Methyl-Seq Kit: a novel post–bisulfite conversion library prep method for methylation analysis

Abstract

Epigenomics is increasingly becoming an important field of research, and the ability to detect and quantify DNA methylation accurately is now critical for numerous fields of study, including disease biology and gene expression. The differential reactivities of methylated and nonmethylated cytosines in DNA with sodium bisulfite forms the basis for their identification in the genome by sequencing. Current whole-genome bisulfite sequencing methods require substantial amounts of starting DNA to compensate for the loss due to bisulfite-mediated DNA degradation. To address issues with sample preparation, we have developed the EpiGnome^™ Methyl-Seq Kit, which utilizes a novel pre-library bisulfite conversion scheme to prepare whole-genome bisulfite sequencing libraries with no sample loss and with only 50 ng of input genomic DNA.
