Enzymatic Methyl Sequencing

Introduction to Enzymatic Methyl Sequencing

DNA methylation at the C5 position of cytosine plays a crucial role in gene expression and chromatin remodelling. As one of the most important research areas in epigenetics, methyl-seq tech is .With the development of high-throughput sequencing technology, WGBS has gradually become the gold standard for DNA methylation sequencing.

Enzymatic Methyl Sequencing has been developed to overcome the shortcomings of WGBS, an enzyme-based method for the detection of 5mC and 5hmC at the single base level. The enzymatic conversion method is gentler and causes less DNA damage, thereby avoiding DNA molecule cleavage and loss.

Enzymatic methylation sequencing Highlights

  • Enzyme based method Minimizes damage to DNA molecules
  • Less DNA input required
  • Less sequencing depth required
  • Superior performance compared to bisulfide sequencing
  • cfDNA is acceptable

Enzymatic methylation sequencing Specifications: DNA Sample Requirements

Sample Type Amount Purity or fragment size
Genomic DNA ≥ 50 ng Fragments are above 5000 bp, and mainly above 13000 bp, no degradation, no contamination, no EDTA
cfDNA ≥ 50 ng Agilent 2100 peak at 170bp and integer multiples, no genomic contamination, no contamination, no EDTA

Project Workflow of Novogene enzymatic methylation sequencing Service

The Novogene enzymatic methylation sequencing service comprises four steps: Sample preparation, library preparation, sequencing, and bioinformatics analysis, DNA extraction service is also available. The enzymatic methylation sequencing conversion reaction is a two-step process: 1) TET2 and T4-BGT Protection of 5mC and 5hmC. 2) APOBEC then deaminates cytosines into uracils. Please contact us for more information about your enzymatic methylation sequencing projects.

To guarantee the accuracy and reliability of sequencing data, Novogene audits every experimental step through quality control, fundamentally ensuring high-quality data output from sampling to the final data report. This commitment to high-quality data is essential for the correctness, comprehensiveness, and credibility of bioinformatics analysis.
