Sequence key genes and regions of interest in a single assay

Save time and money by using preselected or custom gene panels to assess multiple samples at once

Target Enrichment

With targeted resequencing, a subset of genes or regions of the genome are isolated and sequenced. Target enrichment works by capturing genomic regions of interest by hybridization to target-specific biotinylated probes, which are then isolated by magnetic pulldown.

Illumina DNA Prep with Enrichment is the latest innovation in next-generation sequencing (NGS) target enrichment solutions. By combining bead-linked transposome-mediated tagmentation chemistry with hybrid-capture target enrichment, researchers can reduce workflow time and produce an accurate, reliable assay for target enrichment resequencing.

What is Target Enrichment?

Hybridization-based enrichment is a useful strategy for analyzing specific genetic variants in a given sample.

Target enrichment allows researchers the ability to reliably sequence exomes or large numbers of genes (e.g. > 50 genes) using robust and straightforward workflows. It delivers dependable results across a wide range of input types and quantities. Uses include:

  • Human whole-exome sequencing
  • Predesigned (fixed) sequencing panels for cancer and genetic disease research
  • Custom genomic sequencing
Human whole-exome sequencing

Hybrid capture-based target enrichment lets researchers target regions of the genome that are relevant to their specific research interests. Targeted resequencing delivers higher discovery power (ability to identify novel variants), and higher mutation resolution than PCR or Sanger sequencing.

Compared to PCR-based amplicon sequencing, hybridization-based enrichment sequencing can target a higher amount of total gene content and support more comprehensive profiling of all variant types. The larger amount of total gene content allows for the characterization of both known and novel variants for discovery-related applications.

Benefits of Target Enrichment vs. Amplicon Sequencing*
Target Enrichment
Amplicon Sequencing
Larger gene content, typically > 50 genes Smaller gene content, typically < 50 genes
More comprehensive profiling for all variant types Ideal for analyzing single nucleotide variants and insertions/deletions (indels)
More comprehensive method, but with longer hands-on time and turnaround time** More affordable, easier workflow

* Data on file, Illumina 2018.
** The turnaround time is for library prep assay time (DNA to finished library).
