In this introductory talk to our PAG 2020 workshop, PacBio Chief Scientific Officer Jonas Korlach presents the evolution of Single Molecule, Real-Time (SMRT) Sequencing technology over the past decade and highlights recent developments, including the Sequel II System performance and reliability
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.
Jana U’Ren of the University of Arizona discusses the fungi that live inside of plants at a PacBio workshop at the PAG 2020 conference. U’Ren studies the biology and evolution of mycorrhizal fungi found in the photosynthetic tissue of plant leaves, which are grouped together functionally as endophytes. In this video, she shares some of her preliminary findings collecting and analyzing samples from Boreal forests around the world.
In this PacBio User Group Meeting presentation, Shawn Trojahn of Washington State University describes transcriptome sequencing and analysis of grizzly bears focused on differential gene expression during hibernation and active cycles, potentially offering human-relevant information about muscle atrophy and insulin resistance. The team was able to identify more unique isoforms just from liver tissue than had been previously characterized in the entire reference genome. Of particular interest: more than 2,000 transcripts differentially expressed between hibernation and active season, including 86 genes that have isoforms expressed in opposite directions.
In this webinar we present Single Molecule, Real-Time (SMRT) Sequencing and the Iso-Seq method, which allow you to generate full-length cDNA sequences — no assembly required — to characterize transcript isoforms within targeted genes or across an entire transcriptome. The presenters share how the Iso-Seq method: (1) Provides high quality, full-length transcript sequences of up to 15 kb; (2) Allows for one-day library prep on a single SMRT Cell 8M to comprehensively characterize a whole transcriptome; (3) Facilitates discovery of alternative splicing events, fusion gene detection, and allelic specific isoform detection; and (4) Enables discovery of potential cancer-specific isoforms in…
Understanding interactions among plants and the complex communities of organisms living on, in and around them requires more than one experimental approach. A new method for de novo metagenome assembly, PacBio HiFi sequencing, has unique strengths for determining the functional capacity of metagenomes. With HiFi sequencing, the accuracy and median read length of unassembled data outperforms the quality metrics for many existing assemblies generated with other technologies, enabling cost-competitive recovery of full-length genes and operons even from rare species. When paired with the ability to close the genomes of even challenging isolates like Xanthomonas, the PacBio Sequel II System is…
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, Shawn Levy from the HudsonAlpha Institute for Biotechnology and HudsonAlpha Discovery offers a look at his team’s early access experience with the Sequel II System. Recent work includes a project designed to improve sequencing results from FFPE samples with long-read data. The protocol is still being optimized, but preliminary results indicate that SMRT Sequencing improves the quality of data that can be produced from these highly degraded samples. Looking ahead, Levy’s team will be using SMRT Sequencing to generate about 7,000 long-read genome assemblies for the All of Us program.
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.
Highly accurate long reads, known as HiFi reads, are a new tool in scientists’ sequencing toolbox. Hear PacBio users share how they are using HiFi reads to explore the genomes, transcriptomes, metagenomes and the benefits HiFi reads provide for their addressing critical life science questions.
During a PAG 2020 workshop, Zev Kronenberg, a senior bioinformatics engineer at PacBio, describes how he used the PacBio Iso-Seq transcriptome sequencing and analysis method to annotate great ape genomes, detangle several complicated loci, and enrich our biological understanding of the differences between apes and humans.
In this talk at PAG 2020, PacBio Plant and Animal Sciences Marketing Manager Michelle Vierra discusses recent updates to Single Molecule, Real-Time (SMRT) Sequencing technology, including the Sequel II System, updated protocols for low-input as well as other upcoming developments.
Accurate sequencing data is key for University of Florida scientist Ana Conesa. She is using PacBio HiFi reads from the Sequel II System to identity alternative isoforms and determine the functional impact of different isoform expression in her transcriptome research.
PacBio Sequencing is powered by Single Molecule, Real-Time (SMRT) Sequencing technology. The Sequel II System offers the affordable, highly accurate long reads needed to gain comprehensive views of genomes, transcriptomes, and epigenomes. Watch this video to get to know the Sequel II System, explore the key advantages of SMRT Sequencing, and learn how its applications can be used to drive new discoveries.
In this webinar, Dr. Ashby gives attendees a brief update on PacBio’s metagenomics solutions on the Sequel II System. Then, Dr. Ma, University of Maryland School of Medicine, discusses her work using long read sequencing to identify high-resolution microbial biomarkers associated with leaky gut syndrome in premature infants. Finally, Dr. Weinstock, The Jackson Laboratory, talks about the potential of highly accurate long reads to enable strain-level resolution of the human gut microbiome by resolving intraspecies variation in multiple copies of the 16S gene.
