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.
Scientists at UC Davis School of Medicine have used the PacBio RS to sequence a previously “unsequenceable” region of highly repetitive DNA on the X chromosome. Their research has provided a critical leap forward in understanding the genetic complexity of repeat expansion disorders such as Fragile X Syndrome. The new method provides a path towards the first accurate means of population screening for Fragile X Syndrome, which is the most common cause of inherited intellectual disability and the most common known genetic cause of autism.
In an interview with Theral Timpson — part of Mendelspod’s series on long-read sequencing — Ulf Gyllensten, a professor in Medical Molecular Genetics at Uppsala University, spoke about using PacBio technology for HLA typing, human genome studies, transcriptomics, and more.
Single Molecule Real-Time (SMRT) Sequencing delivers reads that span the lengths of the majority of HLA class I and II genes. Unambiguously phase 4-field HLA types without imputation. With a more accurate and complete picture, gain deeper understanding of immune-related disease causality, graft-versus-host disease in hematopoietic transplantation, and drug hypersensitivity.
In order to understand the molecular mechanisms governing the outcomes of disease, health and survival, immunologists have to characterize exceptionally complex genomic regions, like major histocompatibility complex (MHC), killer cell immune receptors (KIR), and the B and T-cell immune repertoire. Single Molecule, Real-Time (SMRT) Sequencing delivers the long read lengths, uniform coverage and high accuracy necessary to comprehensively and confidently resolve these immune sub-genomic regions. The granularity of data generated by PacBio® reads provides new access to imputation-free characterization of genes and haplotypes for invaluable genomic insights to advance disease association and evolutionary research.
With PacBio long-read sequencing, scientists are making exciting new discoveries about the microbes that live around and within us. From viruses to bacteria to fungi, SMRT Sequencing is shedding light on how these organisms function and evolve.
At the University of California, Davis, Dario Cantu is applying long-read PacBio sequencing to the heterozygous genome of the Cabernet Sauvignon grape. Now, his team has access to whole genome data that could help guard against the effects of climate change and disease.
To understand the genetic factors underlying health and disease and to address hidden heritability, scientists require a more comprehensive view of all the variations in the human genome. Single Molecule, Real-Time (SMRT) Sequencing delivers the read lengths, uniform coverage, and accuracy needed for accessing the complete size spectrum of sequence variant types — from single nucleotides to complex structural variants. PacBio’s long single-molecule reads also provide direct variant phasing information across full-length genes and chromosome haplotype blocks. With SMRT Sequencing, scientists gain new insight into the genetic basis of health and disease.
Several new high-quality human genome assemblies produce ethnicity-specific reference sequences and show how scientists can use this genetic information to improve precision medicine studies in Asian sub- populations. These projects demonstrate how long- read SMRT Sequencing provides robust detection of polymorphic structural variants in clinically relevant gene coding regions and phases variants into haplotypes.
The Wisconsin National Primate Research Center (WNPRC) is a leading Major Histocompatibility Complex (MHC) typing lab that focuses on monkeys. While many scientists are familiar with the importance of characterizing the histocompatibility region of the human genome for applications like disease research or tissue typing before organ transplantation, fewer are aware of the need to accurately type this region in non-human primates. At the primate research lab, part of the University of Wisconsin- Madison, scientists are analyzing immune regions to help test potential HIV vaccines and AIDS therapies. Their work is essential for understanding the effects of treatment ahead of…
With the PacBio no-amplification (No-Amp) targeted sequencing method, you can now sequence through previously inaccessible regions of the genome to provide base-level resolution of disease-causing repeat expansions. By combining the CRISPR/Cas9 enrichment method with Single Molecule, Real-Time (SMRT) Sequencing on the Sequel Systems you are no longer limited by hard-to-amplify targets.
The Sequel II System is powered by Single Molecule, Real-Time (SMRT) Sequencing, a technology proven to produce highly accurate long reads, known as HiFi reads, for sequencing data you and your customers can trust.

During the past decade, the search for pathogenic mutations in rare human genetic diseases has involved huge efforts to sequence coding regions, or the entire genome, using massively parallel short-read sequencers. However, the approximate current diagnostic rate is
