The study of genomics has revolutionized our understanding of science, but the field of transcriptomics grew with the need to explore the functional impacts of genetic variation. While different tissues in an organism may share the same genomic DNA, they can differ greatly in what regions are transcribed into RNA and in their patterns of RNA processing. By reviewing the history of transcriptomics, we can see the advantages of RNA sequencing using a full-length transcript approach become clearer.
At Cold Spring Harbor Laboratory, scientists used SMRT Sequencing to decode one of the most challenging cancer genomes ever encountered. Along the way, they built a portfolio of open-access analysis tools that will help researchers everywhere make structural variation discoveries with long-read sequencing data.
With Single Molecule, Real-Time (SMRT) Sequencing and the Sequel Systems, you can easily and affordably sequence complete transcript isoforms in genes of interest or across the entire transcriptome. The Iso-Seq method allows users to generate full-length cDNA sequences up to 10 kb in length — with no assembly required — to confidently characterize full-length transcript isoforms.
Discover the benefits of HiFi reads and learn how highly accurate long-read sequencing provides a single technology solution across a range of applications.
With PacBio single-cell RNA sequencing using the Iso-Seq method, you can now distinguish between alternative transcript isoforms at the single-cell level. The highly accurate long reads (HiFi reads) can span the entire 5′ to 3′ end of a transcript, allowing a high-resolution view of isoform diversity and revealing cell-to-cell heterogeneity without the need for assembly.
In this SMRT Science Journal Club talk, Anoushka Joglekar from Weill Cornell Medicine discusses how she and her colleagues are developing tools to produce an isoform view of the brain…
Alternative splicing of RNA is an important mechanism that increases protein diversity and is pervasive in the most complex biological functions. While advances in RNA sequencing methods have accelerated our understanding of the transcriptome, isoform discovery remains computationally challenging due to short read lengths. Here, we describe the Isoform Sequencing (Iso-Seq) method using long reads generated by the PacBio RS II. We sequenced rat heart and lung RNA using the Clontech® SMARTer® cDNA preparation kit followed by size selection using agarose gel. Additionally, we tested the BluePippin™ device from Sage Science for efficiently extracting longer transcripts = 3 kb. Post-sequencing, we developed a novel isoform-level clustering algorithm to generate high-quality transcript consensus sequences. We show that our method recovered alternative splice forms as well as alternative stop sites, antisense transcription, and retained introns. To conclude, the Iso-Seq method provides a new opportunity for researchers to study the complex eukaryotic transcriptome even in the absence of reference genomes or annotated transcripts.
