Focusing On Your Interests By Targeted Ngs Sequencing

Target Enrichment approaches are commonly used in next-generation sequencing (NGS) workflows to effectively save on sequencing costs by eliminating genes or regions that are not of interests. Through target enrichment sequencing, one can focus on the specific regions and obtain greater depth enough for subsequent analysis with less time and expense when compared to whole genome sequencing.


The two most popular techniques for NGS target enrichment are hybridization capture-based and multiplex PCR-based enrichment (amplicon sequencing), both of which are essential and have been widely used in many fast-growing clinical, academic and industrial applications. To meet the increasing demand for different targets of interests, iGeneTech has developed varies of proven panels based on TargetSeq® Hybridization Capture Sequencing Technology, BisCap® Methyl  Hybridization Capture Sequencing Technology as well as MultipSeq® Multiplex Amplicon Sequencing Technology, where customization is also available to build your own panels.


iGeneTech hybridization capture-based and multiplex PCR-based enrichment can also be applied to Sanger sequencing and third-generation sequencing. Please Contact Us for any questions and inquires.

FAQs

How to determine whether the data of the TargetSeq® Panel are qualified?

For qualified samples, most of the human DNA TargetSeq® panels can be evaluated by using the criteria of Coverage rate (%) > 99%, Target reads capture rate (%) > 50%, T 20% X coverage rate (%) > 97%. For TargetSeq® panels of other species, the performance might vary due to the differences of reference genome, target regions and strains.

Can I use TargetSeq® panels to detect CNV? Does it need any special design?

We provide different design strategy to detect CNV according to its different sizes. For CNVs over 10 kb, a strategy called CNV backbone can be used by including high MAF SNPs at the intervals based on the target CNV sizes. For exon level CNVs (100 to 1000 bp), panels can be designed by covering all the related exon regions. The AIExome® Human Exome Panel V3 – Inherit includes the specially designed CNV backbone, which can be used for CNVs over 500 kb at whole genome level and CNVs over 50 kb at curated regions.

Will the designed coverage of the target region be 100%?

There are some regions in the genome that we classify as hard-to-capture regions, including high GC content sequences, repetitive sequences and homologous sequences. Based on the evaluation result, some of these target regions might be dropped as they might affect the overall performance or introduce errors. The probe coverage of most designs will be over 99% and the missed regions will be specified in probeMissed.bed.

Are the panel design strategtes for DNA and RNA capture the same?

No. DNA panels are designed based on the reference genome, while the RNA panels are designed based on the transcripts. RNA panels normally include additional probes at the edge of exons in order to increase the detection rate of fusions.

What is the difference between Loci.bed and ProbeCov.bed in the design report, and which one should I use?

In our design report, we provide different versions of bed files for different analysis. Loci.bed and ProbeCov.bed are the bed files for target regions and the regions covered by actual probes, respectively. Please select the appropriate bed file according to your requirements. Please be noted that if the target is a point mutation or the panels includes the genome fixed/novel patches, the performance evaluated by using Loci.bed and ProbeCov.bed will be significantly different.


What does the design strategy for DNA capture panels look like?

For human panels, TargetSeq® panel uses the 3X tiling design strategy based on thermodynamic stability, and a specifically optimized multi-factor strategy for hard-to-capture regions and different variation types to improve the overall performance and the detection rate of key markers. For other species, based on the self-developed algorithm, we will perform the evaluation of the genome first and design the panels using different tiling strategy to ensure the balance of the performance and the cost.
