With highly accurate long reads (HiFi reads) from the Sequel IIe System, powered by Single Molecule, Real-Time (SMRT) Sequencing technology, you can efficiently and cost effectively validate gene editing techniques including adeno-associated virus (AAV) and CRISPR-Cas9 approaches.
In this webinar, Lori Aro and Cheryl Heiner of PacBio describe how high-throughput amplicon sequencing using Single Molecule, Real-Time (SMRT) Sequencing and the Sequel System allows for the easy and cost-effective generation of high-fidelity, long reads from amplicons ranging in size from several hundred base pairs to 20 kb. Topics covered include the latest advances in SMRT Sequencing performance for detection of all variant types even in difficult to sequence regions of the genome, multiplexing options to increase throughput and improve efficiency, and examples of amplicon sequencing of clinically relevant targets.
In this AGBT presentation, Marty Badgett shares a look at the latest results from circular consensus sequencing (CCS) mode for highly accurate reads and data from our soon-to-be-released Sequel II System. As he demonstrates, CCS reads cover the same molecule many times, delivering high consensus accuracy despite noisy raw reads; on average, reaching 10 passes achieves Q30 accuracy. Badgett offers several examples where this is useful, such as pharmacogenomic gene analysis and resolving metagenomic communities. He also provides an update on the Iso-Seq method, which can now segregate transcripts into haplotype-specific alleles using a new tool called Iso-Phase.
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.
Discover how the CRISPR-Cas9 system and PacBio long-read sequencing enable targeting of previously unsequencable regions of the genome, including long repeat expansions.

To start Day 1 of the PacBio User Group Meeting, Jonas Korlach, PacBio CSO, provides an update on the latest releases and performance metrics for the Sequel II System. The longest reads generated on this system with the SMRT Cell 8M now go beyond 175,000 bases, while maintaining extremely high accuracy. HiFi mode, for example, uses circular consensus sequencing to achieve accuracy of Q40 or even Q50.
In this PacBio User Group Meeting presentation, PacBio scientist Kristin Mars speaks about recent updates, such as the single-day library prep that’s now possible with the Iso-Seq Express workflow. She also notes that one SMRT Cell 8M is sufficient for most Iso-Seq experiments for whole transcriptome sequencing at an affordable price.
In this webinar, Jonas Korlach, Chief Scientific Officer, PacBio provides an overview of the features and the advantages of the new Sequel II System. Kiran Garimella, Senior Computational Scientist, Broad Institute of MIT and Harvard University, describes his work sequencing humans with HiFi reads enabling discovery of structural variants undetectable in short reads. Luke Tallon, Scientific Director, Genomics Resource Center, Institute for Genome Sciences, University of Maryland School of Medicine, covers the GRC’s work on bacterial multiplexing, 16S microbiome profiling, and shotgun metagenomics. Finally, Shane McCarthy, Senior Research Associate, University of Cambridge, focuses on the scaling and affordability of high-quality…
In this PacBio User Group Meeting presentation, Mitchell Vollger of the University of Washington used HiFi reads from SMRT Sequencing to study segmental duplications in the human genome. The technique significantly reduced the complexity of accurately mapping these nearly identical sequences throughout the genome; it also reduced the amount of compute power needed compared to a previous PacBio assembly using continuous long reads instead of circular consensus sequencing. Despite generating less data with the HiFi assembly, the team still resolved 30% more segmental duplications with the new approach.
To start Day 2 of the PacBio User Group Meeting, Jonas Korlach, PacBio CSO, provides an update on lowering DNA input amounts for SMRT Sequencing workflows. Updates include a more robust shearing method, a revised AMPure size selection, and introduction of multiplexing low input samples. Finally, the use of HiFi sequencing with low input results in a more complete genome assembly. Jonas closes by mentioning that the low DNA input protocol is now available and further advancements to lower input requirements even more will open opportunities for different samples, such as cancer needle biopsies.
In this PacBio User Group Meeting presentation, PacBio scientist Meredith Ashby shared several examples of analysis — from full-length 16S sequencing to shotgun sequencing — showing how SMRT Sequencing enables accurate representation for metagenomics and microbiome characterization, in some cases even without fully assembling genomes. New updates will provide users with a dedicated microbial assembly pipeline, optimized for all classes of bacteria, as well as increased multiplexing on the Sequel II System, now with 48 validated barcoded adapters. That throughput could reduce the cost of microbial analysis substantially.
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 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.
In this presentation at PAG 2020, Bart Nijland of Genetwister Technologies explains how his team set out to make a haplotype-aware assembly of the highly complex tetraploid Rosa x hybrida L. genome in order to capture its full range of genetic variation. HiFi reads generated from PacBio’s Sequel II System have made it possible to parse out critical information from many of the plant’s parental genes.
