In this PacBio User Group Meeting presentation, Garth Ehrlich of Drexel University College of Medicine shares his work on developing a microbiome assay that uses SMRT Sequencing to provide high-quality coverage of the 16S bacterial rRNA for species identification. The microbiome analysis pipeline, MCSMRT, takes advantage of PacBio circular consensus sequencing (CCS) technology and second-generation pathway analysis system for generating extremely high-fidelity sequences that provide the user with ultra-high-confidence species-level microbiome data.
In this PacBio User Group Meeting presentation, Zev Kronenberg of PacBio presents on using the combination of PacBio and Phase Genomics data and analysis tools to create highly contiguous genome assemblies.
In this PacBio User Group Meeting presentation, Chris Boles of Sage Science presents updates on the Sage System for getting the largest DNA fragments using the SageHLS.
In this PacBio User Group Meeting presentation, Bruce Kingham of the DNA Sequencing & Genotyping Center at the University of Delaware describes tips on using the FEMTO Pulse for large-insert libraries.
In this PacBio User Group Meeting presentation, Tina Graves-Lindsay of the McDonnell Genome Institute and the Genome Reference Consortium speaks about the importance of phasing human reference genomes. Her team is now working on its fifteenth human genome assembly — part of a major effort to improve genomic representation of ethnic diversity — with a pipeline that generates 60-fold PacBio coverage for a de novo assembly, followed by scaffolding with other technologies. They are also using FALCON-Unzip to separate haplotypes, leading to reference-grade diploid assemblies. This approach has already helped resolve errors seen in other genomes and even the gold-standard…
In this PacBio User Group Meeting presentation, Jonas Korlach and Roberto Lleras share the latest updates to the structural variation application and analysis tools.
PacBio CSO, Jonas Korlach, kicks off the North America 2018 User Group Meeting with a recap of how SMRT Sequencing has evolved and a preview of the Sequel System 6.0 release. Learn more about this release at: https://www.pacb.com/products-and-services/sequel-system/latest-system-release/
In this PacBio User Group Meeting presentation, Tim Smith of the USDA’s Agricultural Research Service describes efforts to generate reference-grade genome assemblies for various bovine species and analyze them to understand factors such as how selective breeding has affected certain breeds. Genome assemblies he presents span cattle, water buffalo, and gaur. Smith shows data for each assembly, noting that as data production shifted to the Sequel System, long-read PacBio data became even better at producing highly contiguous assemblies.
Jonas Korlach kicks off Day 2 of the 2018 User Group Meeting by discussing a recent collaboration and technique for low-input starting material and high quality de novo assembly projects. While new and not yet fully supported, many researchers have interest in starting with lower amounts of DNA for whole genome sequencing. This protocol requires Express Kit v2, which will be available in early 2019.
Jonas Korlach closes the 2018 User Group Meeting with an outlook and perspectives on SMRT Sequencing, highlighting what possibilities the Sequel System 6.0 release. Learn more about this release at: https://www.pacb.com/products-and-services/sequel-system/latest-system-release/
PacBio Customers present their latest research in short talks at our User Group Meeting. The applications presented span the range of SMRT Sequencing applications from users from around North America.
In this PacBio User Group Meeting lightning talk, Alexandra Pike of MIT presents a study of TIN2, a telomere-binding protein, which is mutated in some short telomere syndromes. By pairing the Iso-Seq method with CRISPR, her team revealed a previously uncharacterized TIN2 isoform that may have a functional difference for individuals with these syndromes.
In this PacBio User Group Meeting lightning talk, Masako Nakanishi presents a study of how the gut microbiome alters an organism’s susceptibility to colonic ulceration; next, she plans to examine cause and effect by evaluating results of fecal transplants in mice.
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, Mount Sinai’s Ethan Ellis presents results from the HLS-CATCH method, which involves the use of the SageHLS instrument with CRISPR design methods to target and extract large genomic fragments for sequencing while avoiding pseudogenes and other confounding regions.
