Whole Exome Sequencing
Whole exome sequencing (WES) investigates genetic variations of underlying diseases such as cancers, Mendelian diseases, and complex human disorders. This method targets protein-coding regions responsible for disease-related variants, providing a more cost-effective approach than whole genome sequencing (WGS).
We offer customizable human and mouse WES solutions at the research-use only (RUO) level and clinical whole exome sequencing solutions in our CLIA-certified and CAP-accredited lab.
How does whole exome sequencing work?
Whole exome sequencing works by using capture probes (synthesized oligonucleotides) or baits designed to specifically hybridize the exons (coding portions of genes), rather than enriching all the genomic DNA. Library preparation comes next, wherein sequencing adapters are added to the enriched protein-coding DNA fragments and sequenced via high-throughput sequencing, often next generation sequencing (NGS).
What is an exome sequencing sequence?
An exome sequencing sequence is the protein-coding region of the genome, known as the exome, that is sequenced via next generation sequencing (NGS). The resulting sequencing data is then used to identify genetic variants and influences on disease.

Webinar| Non-Classical Sources of Tumour-Specific Antigen in Checkpoint Inhibitor Response
Developing immunotherapies for cancer can be difficult due to the variation of immune response from patient to patient. In this webinar, Dr. Litchfield from UCL Cancer Institute presents his team’s exploratory research using a multiomics approach to better understand the diversity of immune response to cancer and highlights their findings of an alternative source of a tumour-specific antigen in checkpoint inhibitor (CPI) response.
