A brief animated introduction to Pacific Biosciences’ Single Molecule, Real-Time (SMRT) Sequencing, including the SMRT Cell and ZMW (zero mode waveguide).
Mario Caccamo, head of bioinformatics at The Genome Analysis Centre (TGAC) in the UK, integrates many different sequencing technologies to get the best of each for optimal genome assemblies, analysis, and annotation. He uses PacBio’s SMRT Sequencing due to its unique long reads for scaffolding and finishing genomes.

Stanford University developmental biologist Lucy Shapiro discusses a collaborative research effort with PacBio sequencing that revealed previously unknown aspects of how chromosome methylation regulates cell cycle progression in Caulobacter. The ability to detect DNA modifications through SMRT Sequencing proved critical in determining methylation states throughout the cell cycle.
Paul Hagerman, MD/PhD, a professor in the biochemistry and molecular medicine department at UC Davis discusses the use of PacBio SMRT sequencing technology for the fragile X gene. Hagerman says the PacBio RS is able to sequence through more than a kilobase of the CGG trinucleotide repeat element underlying Fragile X Syndrome — something no other sequencing platform has achieved. He also plans to use the data to study methylation of this gene, which tends to occur in cases where there are more than 200 copies of the CGG element.
Penelope Bonnen, an assistant professor at Baylor College of Medicine, discusses her use of PacBio SMRT sequencing to look at whole mitochondrial genomes as she reviews her AGBT 2012 poster. Dr. Bonnen is studying a Micronesian population with unusually high rates of obesity, diabetes, and cardiovascular disease to figure out how mitochondrial genetics contributes to adult-onset metabolic syndrome. She describes two approaches in a pilot project for full-length mitochondrial sequencing: one using a 500-base pair insert library and another directly sequencing the single 17 kb amplicon.
This animation depicts a process by which single molecule SMRTbells are loaded in the Zero Mode Waveguides (ZMWs) of the PacBio RS II sequencing system using the automated MagBead Station.
Bart Weimer, a professor at the University of California, Davis, who is leading the 100K Foodborne Pathogen Genome Project, talks about using PacBio sequencing to produce long reads for microbial genomes as well as to study how bacteria use epigenetics to regulate gene expression.
PacBio customers discuss their applications of PacBio SMRT Sequencing and long reads, including Lemuel Racacho (Children’s Hospital of Eastern Ontario Research Institute), Matthew Blow (JGI), Yuta Suzuki (U. of Tokyo), Daniel Geraghty (Fred Hutchinson Cancer Center), and Mike Schatz (CSHL)
The Sequel System, powered by Single Molecule, Real-Time (SMRT) Technology, delivers long reads, high consensus accuracy, uniform coverage and epigenetic characterization. This newly introduced platform provides higher throughput, a reduced footprint and lower sequencing project costs compared to the PacBio RS, the original long-read sequencer.
In this webinar, the presenters describe a targeted sequencing workflow that combines Roche NimbleGen’s SeqCap EZ enrichment technology with PacBio’ SMRT Sequencing to provide a more comprehensive view of variants and haplotype information over multi-kilobase, contiguous regions. They demonstrate that 6 kb fragments can also be utilized to enrich for long fragments that extend beyond the targeted capture site and well into (and often across) the adjacent intronic regions. When combined with SMRT Sequencing, multi-kilobase genomic regions can be phased and variants, including complex structural variants, can be detected in exons, introns and intergenic regions.
Grant Cramer from the University of Nevada, Reno, and Dario Cantu from the Univeristy of Callifornia, Davis, discuss past challenges with sequencing Clone 8 of Cabernet Sauvignon (Vitis vinifera). An assembly of the genome was attempted with approximately 110x Illumina reads and 5x PacBio reads. The PacBio SMRT Sequencing read made major improvements in the assembly compared with the results of Illumina reads only. However, the assembly results were still unsatisfactory, so an additional 100-fold SMRT Sequencing coverage had been generated. An update on the current sequencing results and status of the assembly are presented.
Jonas Korlach presents data from the new Sequel System and discussed the value of SMRT Sequencing for addressing complex disease. He shows comparisons of Sequel data to PacBio RS II data in applications such as targeted sequencing of structural variants, somatic variation detection of cancer samples, and full-length isoform transcript sequencing.
In this AGBT 2017 poster, Ulf Gyllensten from Uppsala University presents two local reference genomes generated with PacBio and Bionano Genomics data. These assemblies include structural variation and repetitive regions that have been missed with previous short-read efforts, including some new genes not annotated in the human reference genome.
PacBio SMRT Sequencing is fast changing the genomics space with its long reads and high consensus sequence accuracy, providing the most comprehensive view of the genome and transcriptome. In this webinar, I will talk about the various data analysis tools available in PacBio’s data analysis suite – SMRT Link – as well as 3rd party tools available. Key applications addressed in this talk are: Genome Assemblies, Structural Variant Analysis, Long Amplicon and Targeted Sequencing, Barcoding Strategies, Iso-Seq Analysis for Full-length Transcript Sequencing
