Whole Genome Bisulfite Sequencing Frequently Asked Questions

 

General Questions

 

1. How do you perform Whole Genome Bisulfite Sequencing?

We offer Whole Genome Bisulfite Sequencing (WGBS) on the Illumina® platform with 2x150 bp configuration.

 

2. What are the differences between the WGBS Service Packages?

The packages differ in price and turnaround time:

  • Value is the most economical: ~10% less in cost and ~2 weeks longer than Preferred
  • Preferred offers a balance of speed and cost, leveraging our optimized processes for industry-leading turnaround time at an affordable price
  • Express is the fastest: ~1 week faster and ~20% more in cost than Preferred

Furthermore, Preferred and Express options include guaranteed turnaround time and dedicated project managers. The package type can be revised after receiving your initial quote. For more information, visit our selection guide.

Note: Service packages are not available for all services, projects, or institutions.

 

3. Which types of modifications can be detected?

Whole Genome Bisulfite Sequencing detects 5-methylcytosine (5mC) residues.


4. Do templates require bisulfite conversion?

No. For Illumina-based WGBS, we accept either bisulfite-treated or untreated DNA.

 

5. What depth of coverage is recommended?

For WGBS, 30X coverage is recommended for human and large eukaryotic genomes and 100X for genomes <100 Mb.

 

6. What data analysis is available for Whole Genome Bisulfite Sequencing?

Our standard WGBS analysis includes methylation site identification, differential methylation analysis, and percent bisulfite conversion on CpG sites.
