Targeted sequencing for human biomedical research

Targeted sequencing allows researchers to focus on genes or regions of interest and generate highly accurate, long-read sequencing data in a cost-effective way.

Resolve complex genomics underlying human disease

Single Molecule, Real-Time (SMRT) sequencing offers a flexible solution for targeting regions of interest, from several hundred base pairs to kilobase scale, and delivers the most comprehensive view of the associated genes. With highly accurate long reads (99.9% single-molecule read accuracy) it delivers the read length and accuracy needed to improve fine mapping and simplify the analysis of complex portions of the genome. SMRT sequencing gives you the ability to:

  • Rapidly screen and identify all variants
  • Discover haplotype-specific markers
  • Resolve difficult-to-sequence regions, regardless of size
  • Confirm insertion sites of transgenes and validate gene editing events

SMRT Sequencing uncovers novel causative mutations and resolves duplicated genes

PacBio long-read sequencing enabled scientists to detect a single causative mutation for autosomal dominate tubulointerstitial kidney disease (ADTKD) in MUC1 gene residing in a GC-rich variable number tandem repeat region (VNTR) that was previously intractable. Explore this research further:

Wenzel, A. et al., 2018. Single molecule real time sequencing in ADTKD-MUC1 allows complete assembly of the VNTR and exact positioning of causative mutationsScientific Reports, 8(1), p.4170.
