Analyse methylation patterns with AllGenetics' bisulphite sequencing service

AllGenetics' bisulphite sequencing service includes both whole-genome bisulphite sequencing (WGBS) and reduced-representation bisulphite sequencing (RRBS) protocols. While WGBS detects methylated cytosines all throughout the genome, RRBS uses a restriction enzyme to enrich the libraries in CpG contexts, where most of the DNA methylation occurs.

This graph shows the different steps of the AllGenetics' bisulphite sequencing service. Therefore it shows a typical workflow of a bisulphite sequencing experiment, including DNA isolation, library preparation, high-throughput sequencing, and bioinformatic analysis.

Step 1

We isolate DNA from your samples. We have adapted different DNA isolation protocols, depending on the starting biological material.

Step 2

We prepare genomic libraries compatible with Illumina's NovaSeq platform. We carry out either WGBS or RRBS protocols in which DNA is treated with bisulphite. In the case of RRBS, a restriction enzyme is used to enrich the libraries in CpG contexts.

Step 3

We sequence the libraries using the Illumina NovaSeq technology. Millions of reads per library are obtained in this step.

Step 4

We analyse the high-throughput sequencing data obtained in the previous step.

For your convenience, we can carry out the entire project or only those steps you require. As a norm, steps 2 and 3 should be ordered jointly.

What you receive

icon
A report with a summary of the methods followed.
icon
The raw high-throughput sequencing files, which will be delivered through our server, and the corresponding quality control report including demultiplexing and pre-processing.

icon
The results of the bioinformatic analysis including read alignment against the reference genome, removal of duplicate reads (WGBS) or quality filtering by restriction sites (RRBS), methylation calling, and detection of differentially methylated positions (DMPs) and regions (DMRs) among conditions. If you require additional analyses, please let us know and we will do our best to meet your needs.
icon
At no additional cost, our project specialists will be available to you after project delivery and during the editorial process of your scientific articles. We offer up to five 60-min sessions per project, depending on the project size.

PRICING EXAMPLE: 934 € / SAMPLE

Price calculated for a standard project of 12 samples, from DNA isolation to bioinformatic analysis. Please note that the more samples we analyse, the lower the prices. VAT not included.
