What is targeted methyl-seq?
Methylation sequencing (methyl-seq), also referred to as bisulfite sequencing, is a next generation sequencing (NGS) approach that researchers use to study methylation patterns of DNA. These patterns can be used to identify different cell types in epigenetics
and oncology research [1,2]. Researchers can study the methylation status of the entire genome using whole genome bisulfite sequencing (WGBS) or target specific regions of the genome using hybridization capture panels to
enrich genomic regions of interest. More specifically, a targeted methyl-seq approach (also called targeted bisulfite sequencing) uses hybridization probes to capture and enrich biologically relevant regions of interest but with deeper sequencing
depth and higher coverage than WGBS.
Targeted methyl-seq workflow
A targeted methyl-seq workflow provides researchers with a streamlined procedure for targeted methylation sequencing. The xGen Methyl-Seq DNA Library Prep Kit has a post-bisulfite library preparation workflow to maximize library complexity by converting bisulfite-induced single-stranded DNA fragments directly into library molecules. This kit is compatible with a range of input quantities and libraries can
be generated in as little as 2 hours from bisulfite‑converted samples.
The addition of an xGen Custom Hyb Panel to this workflow
enables researchers to capture biologically relevant regions of the genome for targeted methyl-seq. When used for targeted methyl-seq, the xGen Custom Hyb Panel results in sequences with a high on-target mapping percentage and efficiency (Figure 1),
as well as methylation profiles that are highly correlated to those obtained from WGBS (Figure 2). Further details on the xGen Custom Hyb Panel for targeted methyl-seq can be found in the AppNote, Cost-effective targeted methyl-seq using an xGen Custom Hyb Capture Panel and the xGen Methyl-Seq DNA Library Prep Kit identifies DNA methylation in low input samples consistent with WGBS.
The recommended group of xGen methyl-seq product offerings also include the compatible core reagents the xGen Hybridization and Wash v2 Kit, xGen Universal Blockers TS, and xGen Library Amplification Primer Mix to accomplish methyl-seq with an easy and flexible workflow.
Together, these xGen NGS products offer you a comprehensive workflow for accelerating your epigenetic research using a targeted methylation sequencing approach.
