Discover how HiFi reads enable every aspect of viral research, from understanding viral genomes to the host immune response.
Learn how Single Molecule, Real-Time (SMRT) Sequencing and the Sequel IIe System and will accelerate your research by delivering highly accurate long reads to provide the most comprehensive view of genomes, transcriptomes and epigenomes.
In this BioConference Live webinar, PacBio CSO Jonas Korlach highlights how multi-kilobase reads from SMRT Sequencing can resolve many of the previously considered ‘difficult-to-sequence’ genomic regions. The long reads also allow phasing of the sequence information along the maternal and paternal alleles, demonstrated by full-length, fully phased HLA class I & II gene sequencing. In addition, characterizing the complex landscape of alternative gene products is currently very difficult with short-read sequencing technologies, and he describes how long-read, full-length mRNA sequencing can be used to describe the diversity of transcript isoforms, with no assembly required. Lastly, in the exciting area of…
Dr. Nezih Cereb, CEO & co-founder of HistoGenetics shares his reasons for adopting the PacBio DNA Sequencing platform for their operations and elaborates how the system’s unique ability to sequence full-length HLA amplicons irrespective of insert size and to provide fully phased HLA alleles will be used for HLA typing.
At the PacBio ASHG workshop, Hagen Tilgner describes how he used long-read sequencing with Iso-Seq method to generate the first personal transcriptomes for three individuals. From these three family members, he and his collaborators were able to unambigously assign allele-specific RNA haplotypes, including HLA haplotypes, and demonstrated Mendelian inheritance of RNA molecules.
Ulf Gyllensten speaks about advances in screening for HPV, his predictions for the widespread use of genome sequencing in the clinic, and applications using Single Molecule, Real-Time (SMRT) Sequencing for human genome studies.
Q&A session following the 2014 ASHI PacBio Workshop with speakers Martin Maiers, Steven Marsh and Nezih Cereb
Ulf Gyllensten from Uppsala University describes his AGBT poster showing the use of SMRT Sequencing for HLA allele typing. He says long reads are essential for sequencing the HLA genes because they link exons in a single read and do not introduce bias, as short-read sequencers can. Looking at fusion transcripts from CML patients generated information that couldn’t be achieved with any other technology, he adds.
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.
Masao Nagasaki from Tohoku University presents in his ASHG 2015 poster on typing of HLA class I genes using SMRT Sequencing. By using long-read sequencing he was able to successfully type these genes for 220 individuals. This included samples that he had previously been unsuccessful typing using short-read sequencing.
One of the popular questions on the Mendelspod program is how those doing sequencing decide between the quality of PacBio’s long reads and the cheaper short read technology, such as that of Illumina or Thermo Fisher. Steve Marsh, the Director of Bioinformatics at the Anthony Nolan Research Institute in London, provides the most clear and dramatic answer yet: use the PacBio system exclusively. Established in 1974 by the mother of a boy with a rare blood disease, the Anthony Nolan Institute is a world leader in blood crossmatching and donor/patient registries. Steve and his team at the Institute have dramatically…
