In this short video, Aaron Wenger, a Principal Scientist at PacBio, explains what highly accurate long reads, or HiFi reads, are and how they help to detect all variant types including single nucleotide, indels, and structural variants. He goes on to recap the precisionFDA Truth Challenge V2 which used Genome in a Bottle (GIAB) benchmarks to evaluate various sequencing technologies. In the 2020 challenge, when ranked for accuracy, PacBio HiFi reads delivered the highest precision and recall in all categories.
Hear how scientists have used PacBio sequencing to develop pangenome collections and to study population genetics of plant and animal species to power their research. Learn about the advantages of sequencing multiple individuals to gain comprehensive views of genetic variation, and understand the speed, cost, and accuracy benefits of using highly accurate long reads (HiFi reads) to sequence your species of interest.
In this webinar, Adam Ameur of SciLifeLab at Uppsala University shares how he uses Single Molecule, Real-Time (SMRT) Sequencing applications for medical diagnostics and human genetics research, including sequencing of single genes and de novo assembly of human genomes as well as a new method for detection of CRISPR-Cas9 off-targets.
In this webinar you will hear how several researchers have overcome the challenges of sequencing organisms with small body size using the new low and ultra-low DNA input methods from PacBio. Learn about the advantages of using highly accurate long reads (HiFi reads) to sequence and de novo assemble genomes of single individuals.
Dr. Wenger gives attendees an update on PacBio’s long-read sequencing and variant detection capabilities on the Sequel II System and shares recommendations on how to design your own study using HiFi reads. Then, Dr. Sund from Cincinnati Children’s Hospital Medical Center describes how she has used long-read sequencing to solve rare neurological diseases involving complex structural rearrangements that were previously unsolved with standard methods.
Studying microbial genomics and infectious disease? Learn how the PacBio Sequel II System can help advance your research, with first-hand perspectives from scientists who are investigating SARS-CoV-2 and COVID-19. In this webinar, Melissa Laird-Smith (Mt. Sinai School of Medicine) discusses her work evaluating the impact of host immune restriction in health and disease with high resolution HLA typing.

The utility of new highly accurate long reads, or HiFi reads, was first demonstrated for calling all variant types in human genomes. It has since been shown that HiFi reads can be used to generate contiguous, complete, and accurate human genomes, even in repeat structures such as centromeres and telomeres. In this virtual workshop scientists from PacBio as well as Tina Graves-Lindsay from the McDonnell Genome Institute at Washington University share the many improvements we’ve made to HiFi sequencing in the past year, tools that take advantage of HiFi data for variant detection and assembly, and examples in numerous genomics…
The Earlham Institute was one of the first labs to adopt the PacBio Sequel II System. Karim Gharbi, Head of Genomics Pipelines, discusses how SMRT Sequencing and HiFi reads have increased throughput and reduced costs for genome, transcriptome, and metagenomics projects.
Jeremy Schmutz discusses the increased throughput and reduced project costs using HiFi reads from the PacBio Sequel II System in his work sequencing, assembling, and analyzing a variety of genomes at the HudsonAlpha Institute for Biotechnology.
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.
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.
Richard Kuo’s research at the Roslin Institute exploring non-coding RNA of avian species requires high accuracy. SMRT Sequencing on the PacBio Sequel II System and the Iso-Seq method have given him confidence in annotations across entire genomes and transcriptomes.
In this LabRoots webinar, Jonas Korlach the CSO of PacBio provides an introduction to PacBio HiFi sequence reads, which are both long (up to 25 kb currently) and accurate (>99%) at the individual single-molecule sequence read level andhave allowed for advances in de novo genome assemblies. Korlach reviews the characteristics of HiFi read data obtained with the Sequel II System, followed by examples of high-quality genome assemblies for human, plant and animal genomes including the different aspects of evaluating genome assemblies (contiguity, accuracy, completeness and allelic phasing) and illustrates their high quality by examples of resolving centromeres, telomeres, segmental duplications…
Zinc finger nucleases (ZFNs) are promising tools for genome editing for biotechnological as well as therapeutic purposes. Delivery remains a major issue impeding targeted genome modification. Lentiviral vectors are highly efficient for delivering transgenes into cell lines, primary cells and into organs, such as the liver. However, the reverse transcription of lentiviral vectors leads to recombination of homologous sequences, as found between and within ZFN monomers.We used a codon swapping strategy to both drastically disrupt sequence identity between ZFN monomers and to reduce sequence repeats within a monomer sequence. We constructed lentiviral vectors encoding codon-swapped ZFNs or unmodified ZFNs from…
Well-developed genetic tools for thermophilic microorganisms are scarce, despite their industrial and scientific relevance. Whereas highly efficient CRISPR/Cas9-based genome editing is on the rise in prokaryotes, it has never been employed in a thermophile. Here, we apply Streptococcus pyogenes Cas9 (spCas9)-based genome editing to a moderate thermophile, i.e., Bacillus smithii, including a gene deletion, gene knockout via insertion of premature stop codons, and gene insertion. We show that spCas9 is inactive in vivo above 42 °C, and we employ the wide temperature growth range of B. smithii as an induction system for spCas9 expression. Homologous recombination with plasmid-borne editing templates…
