Introduction to RNA sequencing using the Iso-Seq method
With long and accurate HiFi reads, you can characterize the full diversity of the transcriptome:
- See alternative start and end sites
- Characterize splicing events
- Identify allele-specific isoforms
- Profile expression at isoform resolution
- Detect fusion genes
- Predict full-length open read frames
- …and more
“More than 50% of isoforms robustly detected using Iso-Seq could not be readily recapitulated using standard RNA-seq, highlighting the advantage of long-read sequencing for characterizing isoform diversity.1”

Advantages of RNA sequencing with the
Iso-Seq method
Powered by HiFi reads, the Iso-Seq method uncovers biology that other approaches miss.
Iso-Seq Method delivers full-length transcript isoforms, no assembly required
Unlike short-read RNA-seq methods, Iso-Seq method reads span the whole transcript, capturing even untranslated regions.
- Detect alternative polyadenylation
- Detect differential isoform usages (DIU)
- Obtain isoform-level phasing information


Iso-Seq Data is comprehensive
Characterize whole transcriptome isoform diversity that can reveal complex alternative splicing, fusion events, and transcriptional readthroughs.
Iso-Seq Analysis offers unparalleled insight at the single cell level
Use any single cell platform to generate full-length cDNA as input for SMRT sequencing and achieve all the same benefits of Iso-Seq on bulk cDNA – complete transcript sequence, isoform-level phasing, and isoform profiling – at single cell resolution.
