To bring personalized medicine to all patients, cancer researchers need more reliable and comprehensive views of somatic variants of all sizes that drive cancer biology.
The Sequel II System, powered by Single Molecule, Real Time (SMRT) Technology, delivers highly accurate long reads for a comprehensive view of genomes, transcriptomes and epigenomes.
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.
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.
With PacBio Single Molecule, Real-Time (SMRT) Sequencing on the Sequel IIe System you can characterize whole genomes and transcriptomes with just one SMRT Cell. Explore our applications and pricing to get your sequencing project started.
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.
Discover the benefits of HiFi reads and learn how highly accurate long-read sequencing provides a single technology solution across a range of applications.

The Sequel System, powered by Single Molecule, Real Time (SMRT) Technology, delivers long reads, high consensus accuracy, uniform coverage and epigenetic characterization.
Most genes in eukaryotic organisms produce alternative isoforms, broadening the diversity of proteins and non-coding RNAs encoded by the genome. In contrast to other RNA sequencing platforms that rely on short-read sequencing, long accurate reads from PacBio Single Molecule, Real-Time (SMRT) Sequencing can characterize full-length transcripts without the need for assembly and inference. The PacBio isoform sequencing (Iso-Seq) method generates full-length sequences for transcripts up to 10 kb in length, with scalable throughput using barcoding approaches. The Iso-Seq application can be employed for a wide variety of studies, including improvement of gene annotation, identification of novel isoforms and fusion transcripts,…
From USDA’s Agricultural Research Service, molecular biologist Sean Gordon discusses the need for long-read sequencing to map an organism’s transcriptome. His team analyzed the wood-decaying fungus Plicaturopsis crispa first with short reads and found that they were missing exons and other important information. They switched to SMRT Sequencing so they could observe, rather than infer, full-length transcripts.
Michiel van Eijk of KeyGene shared a de novo PacBio assembly of tetraploid cotton. The genome assembly was further enhanced and annotated using Iso-Seq data collected from cotton root, leaf, and stem tissues. The data, full-length cDNA transcripts, captured alternative splicing diversity across these tissue types, allowing for isoform differentiation.
In this ASHG 2016 virtual poster, Flora Tassone from UC Davis describes her study of the molecular mechanisms linked to fragile X syndrome and associated disorders, such as FXTAS. She is using SMRT Sequencing to resolve the FMR1 gene in premutation carriers because it’s the only technology that can generate full-length transcripts with the causative CGG repeat expansion. Plus: direct confirmation of predicted isoform configurations.
Tremendous flexibility is maintained in the human proteome via alternative splicing, and cancer genomes often subvert this flexibility to promote survival. Identification and annotation of cancer-specific mRNA isoforms is critical to understanding how mutations in the genome affect the biology of cancer cells. While microarrays and other NGS-based methods have become useful for studying transcriptomes, these technologies yield short, fragmented transcripts that remain a challenge for accurate, complete reconstruction of splice variants. The Iso-Seq method developed at PacBio offers the only solution for direct sequencing of full-length, single-molecule cDNA sequences needed to discover biomarkers for early detection and cancer stratification,…
In this AGBT 2017 talk, PacBio CSO Jonas Korlach provided a technology roadmap for the Sequel System, including plans the continue performance and throughput increases through early 2019. Per SMRT Cell throughput of the Sequel System is expected to double this year and again next year. Together with a new higher-capacity SMRT Cell expected to be released by the end of 2018, these improvements result in a ~30-fold increase or ~150 Gb / SMRT Cell allowing a real $1000 real de novo human genome assembly. Also discussed: Additional application protocol improvements, new chemistry and software updates, and a look at…
