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.
At the Icahn Institute for Genomics and Multiscale Biology, scientists use automated DNA sizing together with long- read sequencing to analyze human samples, conduct routine surveillance on microbes, and more.
Scientists from WashU, Macrogen, and Mount Sinai are using long-read sequencing with single-molecule, next-generation genome mapping to create gold-quality de novo assemblies of human genomes. Unbiased de novo assembled genomes also highlight the substantial amount of structural variation unique to individuals and populations, which cannot be accessed by short-read technologies that use a reference-based re-sequencing approach.
Scientists are utilizing long-read PacBio sequencing to provide uniquely comprehensive views of complex plant and animal genomes. These efforts are uncovering novel biological mechanisms, enabling progress in crop development, and much more. To date, scientists have published over 1000 papers with Single Molecule, Real-Time (SMRT) Sequencing, many covering breakthroughs in the plant and animal sciences. In this case study, we look at examples in model organisms Drosophila and C. elegans and non-model organisms coffee, Oropeitum, danshen, and sugarbeet, where SMRT Sequencing has contributed to a more accurate understanding of biology. These efforts underscore the broad applicability of long-read sequencing in…
At Cold Spring Harbor Laboratory, scientists used SMRT Sequencing to decode one of the most challenging cancer genomes ever encountered. Along the way, they built a portfolio of open-access analysis tools that will help researchers everywhere make structural variation discoveries with long-read sequencing data.
Scientists at the USDA and Cold Spring Harbor Laboratory know that better breeding of maize to feed a growing population will depend on an accurate reference assembly. They tackled the previously intractable crop with a combination of PacBio Sequencing and BioNano Genomics® genome maps, leading to the first-ever high-quality reference assembly.
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.
Single Molecule, Real-Time (SMRT®) Sequencing combines long reads with uniform coverage to provide uniquely comprehensive views of plant and animal genomes and transcriptomes. High-quality genome assemblies and evidence-based annotations promote improved genetic marker development, discovery of novel genes, and structural variation characterization.
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.
Structural variation accounts for much of the variation among human genomes. Structural variants of all types are known to cause Mendelian disease and contribute to complex disease. Learn how long-read sequencing is enabling detection of the full spectrum of structural variants to advance the study of human disease, evolution and genetic diversity.
Explore how long-read sequencing enables solving of rare and mendelian diseases.
The Sequel System, powered by Single Molecule, Real Time (SMRT) Technology, delivers long reads, high consensus accuracy, uniform coverage and epigenetic characterization.
