Iso-Seq

 

Isoform sequencing (Iso-Seq) uses Single Molecular, Real-Time (SMRT®) long-read technology, through PacBio Sequel, to enable sequencing of contiguous full-length transcripts. This method avoids errors that can occur with short-read approaches and captures each transcript’s start, polyadenylation, and splice sites from a single read. Potential applications include better annotated genomes, detection of gene fusion, and discovery of novel isoforms.

The capabilities of Iso-Seq are greatly enhanced on the PacBio Sequel system compared to the older RSII. GENEWIZ Multiomics & Synthesis Solutions from Azenta Life Sciences have further optimized the process to exceed PacBio’s benchmarks in output and read length.

What is Iso-Seq?

The Iso-Seq method generates full-length cDNA sequences and analyzes full-length transcript isoforms, which can be used in RNA sequencing (RNA-Seq) to:

  • See alternative start and end sites
  • Characterize splicing events
  • Find fusion transcripts
  • Identify allele-specific isoforms
  • Discover non-coding RNAs
  • Profile expression at isoform resolution
  • Predict full-length open read frames and more

 

What is the output of Iso-Seq?

The Iso-Seq method and bioinformatics workflow outputs high-quality, full-length transcript sequences of 10kb or longer. The high accuracy of high-fidelity (HiFi) reads ensure that SNPs can be identified, as well as UMIs and barcodes used for single-cell studies.

Iso-Seq delivers full-length transcript isoforms with no assembly required. Unlike short-read RNA-Seq methods, Iso-Seq method reads span the whole transcript, capturing even untranslated regions.

 

What is Iso-Seq analysis using PacBio technology?

Iso-Seq analysis empowers you to discover novel transcripts and genes, identify fusion genes, and annotate isoforms and alternative splicing events. Iso-Seq analysis uses highly accurate long reads (HiFi reads) generated with the CCS algorithm to cluster and generate full-length, high-quality transcript isoforms.

 

What is the depth of Iso-Seq?

The read depth of Iso-Seq is 1.6M full length transcripts.
