Ulf Gyllensten from Uppsala University used SMRT Sequencing to study multi-drug-resistant bacteria. Time to results was faster than other NGS platforms and generally resulted in complete genome assemblies, even for an organism with a 70% AT-rich genome. He also applied SMRT Sequencing for the characterization of HPV subtypes, important in cervical cancer.
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.
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)
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.
Ulf Gyllensten shares how whole genome sequencing with PacBio is revealing variation and regions of the genome never previously known.
Yuta Suzuki from the University of Tokyo details his experience using SMRT Sequencing for generating data for haplotype-specific epigenetic analysis.
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.
At AGBT 2020, Adam Ameur from Uppsala University discussed the use of long-read PacBio sequencing to detect off-target results from CRISPR/Cas9 gene editing studies. His team uses HiFi reads from the Sequel II System to perform whole genome sequencing and figure out exactly where guide RNAs bind. In one example using a human embryonic kidney cell line, they found 55 off-target sites for three guide RNAs. Ameur’s group has already generated preliminary data on results from editing living cells.
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.
Sequence based typing (SBT) is considered the gold standard method for HLA typing. Current SBT methods are rather laborious and are prone to phase ambiguity problems and genotyping uncertainties. As a result, the NGS community is rapidly seeking to remedy these challenges, to produce high resolution and high throughput HLA sequencing conducive to a clinical setting. Today, second generation NGS technologies are limited in their ability to yield full length HLA sequences required for adequate phasing and identification of novel alleles. Here we present the use of single molecule real time (SMRT) sequencing as a means of determining full length/long…
