Structural variation accounts for much of the variation among human genomes. Structural variants of all types are known to cause Mendelian disease and contribute to complex disease. Learn how long-read sequencing is enabling detection of the full spectrum of structural variants to advance the study of human disease, evolution and genetic diversity.
With highly accurate long reads (HiFi reads) from the Sequel II System, powered by Single Molecule, Real-Time (SMRT) Sequencing technology, you can comprehensively detect variants in a human genome. HiFi reads provide high precision and recall for single nucleotide variants (SNVs), indels, structural variants (SVs), and copy number variants (CNVs), including in difficult-to-map repetitive regions.
With the Sequel II System powered by Single Molecule, Real-Time (SMRT) Sequencing technology and SMRT Link v8.0, you can affordably and effectively detect structural variants (SVs), copy number variants, and large indels ranging in size from tens to thousands of base pairs. PacBio long-read whole genome sequencing comprehensively resolves variants in an individual with high precision and recall. For population genetics and pedigree studies, joint calling powers rapid discovery of common variants within a sample cohort.
Discover the benefits of HiFi reads and learn how highly accurate long-read sequencing provides a single technology solution across a range of applications.
As the foundation for scientific discoveries in genetic diversity, sequencing data must be accurate and complete. With highly accurate long-read sequencing, or HiFi sequencing, there is no longer a compromise between read length and accuracy. HiFi sequencing enables some of the highest quality de novo genome assemblies available today as well as comprehensive variant detection in human samples. PacBio HiFi libraries constructed using our standard library workflows require at least 3 µg of DNA input per 1 Gb of genome length, or ~10 µg for a human sample. For some samples it is not possible to extract this amount of…
Learn why it is critically important to understand accuracy in DNA sequencing to distinguish important biological information from sequencing errors.
Learn how Single Molecule, Real-Time (SMRT) Sequencing and the Sequel IIe System will accelerate your research by delivering highly accurate long reads to provide the most comprehensive view of genomes, transcriptomes and epigenomes.
Marc Salit is the leader of the Genome Scale Measurement Group at the National Institute of Standards and Technology or NIST. In this Mendelspod podcast, he explains how NIST played a pivotal, foundational role in enabling the ‘Century of Physics.’ Now Marc and NIST are looking for the right set of standards to enable the already-upon-us “Century of Biology.” The human reference genome is an example of a standard that Marc and his team are developing. Currently they are piloting what they call “Genome in a Bottle,” a physical reference standard to which all other human genomes can be measured.…
PacBio bioinformatician Aaron Wenger presents this ASHG 2016 poster demonstrating human structural variation detection at varying coverage levels with SMRT Sequencing on the Sequel System. Results were compared to truth sets for well-characterized genomes. Results indicate that even low coverage of SMRT Sequencing makes it possible to detect hundreds of SVs that are missed in high-coverage short-read sequencing data.
Jonas Korlach spoke about recent SMRT Sequencing updates, such as latest Sequel System chemistry release (1.2.1) and updates to the Integrative Genomics Viewer that’s now update optimized for PacBio data. He presented the recent data release of structural variation detected in the NA12878 genome, including many more insertions and deletions than short-read-based technologies were able to find.
In this AGBT presentation, Mike Hunkapiller shares insights on using highly accurate long (HiFi) reads generated in circular consensus sequencing (CCS) mode for comprehensive genomic analysis and provides examples such as the sequencing of a Genome in a Bottle reference sample, which concluded with Q48 accuracy, 18 Mb contigs, and clearly phased haplotypes.
In this ASHG workshop presentation , Jonas Korlach, CSO of PacBio, walked attendees through recent product updates and the coming technology roadmap. The Sequel System 6.0 release offered major improvements to accuracy, throughput, structural variant calling, and large-insert libraries, he said, showing examples of 35 kb libraries. Looking ahead, Korlach said that the V2 express library preparation product should be available early in 2019, with the new 8M SMRT Cell being introduced sometime later.
In this webinar, Sarah Kingan, Staff Scientist, PacBio, presents recent work on de novo genome assembly using PacBio HiFi reads. She highlights the benefits of HiFi data for base level accuracy, haplotype phasing, and ease of computation. And in samples ranging from human to plants, she benchmarks various tools for HiFi assembly and phasing, including the newly extended FALCON-Unzip assembler. Subsequently, Andrew Carroll, Genomics Product Lead, GoogleAI, explores how the GoogleAI team retrained DeepVariant, a highly accurate SNP and Indel caller, for PacBio HiFi data. The resulting DeepVariant models achieve comparable accuracies to short-read methods with the additional benefit of…
In this webinar, Kristin Mars, Sequencing Specialist, PacBio, presents an introduction to PacBio’s technology and its applications followed by a panel discussion among sequencing experts. The panel discussion addresses such things as what long reads are and how are they useful, what differentiates PacBio long-read sequencing from other technologies, and the applications PacBio offers and how they can benefit scientific research.
In this presentation, Emily Hatas of PacBio offers a look a how SMRT Sequencing has changed over the years as well as the most common applications in human genome analysis: high-throughput structural variant detection; comprehensive variant detection; and de novo assembly of reference genomes.
