Bring certainty to isoform detection
Changes in isoform variants and relative abundancies are an important clue in deciphering how genomic variants drive the phenotypic differences between health and disease. Only long-read sequencing can provide unbiased, direct detection of all the isoforms present in your sample.
Single Molecule, Real-Time (SMRT) Sequencing delivers the long reads needed to capture intact isoform information without assembly or complicated algorithms. Use the Iso-Seq method to:
- Profile whole transcriptomes exhaustively at the isoform-level
- Characterize alternative start and polyadenylation sites as well as exon skipping events
- Detect isoforms as potential biomarkers
- Target genes of interest using synthetic probes with sample multiplexing to query isoforms in a cost-effective manner

Spotlight: Identify novel full-length isoforms in castration-resistant prostate cancer (CRPR)
Scientists used long-read sequencing to identify and quantify full-length androgen receptor (AR) isoforms expressed in CRPC. They identified a truncated isoform, AR-V9, which shows potential to be a more predictive biomarker than AR-V7 of primary resistance to AR-targeted therapies. Explore this research further:
