    Whole Genome Bisulfite Sequencing (WGBS)

    Whole Genome Bisulfite Sequencing (WGBS) provides a scalable solution for cell characterization and gene expression profiling of hundreds to millions of cells. Tell us about your project, our experts are here to help.

    Whole Genome Bisulfite Sequencing Introduction

    Methylation of DNA at the fifth position in cytosine (5-mC) is a stable epigenetic modification and plays an important role in many biological processes, including gene silencing, suppression of transposable elements, genomic imprinting and X chromosome inactivation. Detection and quantification of methylation are critical to understand gene expression and other processes subjected to epigenetic regulation.

    Whole genome bisulfite sequencing (WGBS) is used to detect methylated cytosines by treating the DNA with sodium bisulfite before sequencing. WGBS has become the gold standard for studying genome-wide methylation at single base resolution.

    Whole Genome Bisulfite Sequencing Technology

    BGI's Whole Genome Bisulfite Sequencing services are typically executed with proprietary DNBSEQ™ sequencing technology platforms, for great sequencing data at some of the lowest costs in the industry. DNBSEQ is a proprietary sequencing technology, first developed by BGI's Complete Genomics subsidiary in Silicon Valley and offers advantages in terms of lower amplification error rates and much lower duplication rates. In addition, studies have shown the index hopping rate in DNBSEQ platforms to be much lower when compared to that of other platforms.
