Long Read Sequencing Industry: Global Long Read Sequencing Market Surges Forward New Advancements and Growing Demand

Long Read Sequencing Industry

A New Era of Long Read Sequencing Industry

Recent advances in long read sequencing technologies are enabling unprecedented insights into genome structure and function. By generating reads that can span entire genes or repeat regions in a single piece of DNA, long read sequencers like the Oxford Nanopore Technologies' MinION and Pacific Biosciences' Sequel II overcome many of the limitations of short read sequencing. Long reads allow for complex genomic regions like tandem repeats to be resolved that were previously intractable with short reads. Researchers can now generate contig assemblies that more fully reconstruct entire genomes and transcriptomes.

Clinical Applications of Long Read Sequencing Industry

Global Long Read Sequencing  is being applied to important clinical applications. Structural variant detection from long reads has helped identify the genetic causes of many rare Mendelian disorders. Assembling complete genomic sequences from long reads enables more accurate characterization of disease-causing mutations, especially in repetitive regions. In cancer genomics, long read methods are illuminating the complex structural changes that occur during tumor evolution. Characterizing genomic rearrangements at nucleotide resolution reveals new insights into cancer progression and has implications for precision oncology. Long read RNA sequencing is also improving clinical diagnosis and surveillance by enabling full-length transcript mapping and isoform variation discovery.

Enhancing reference genomes

Reference genomes underpin modern biomedicine and evolutionary biology. However, many existing reference genomes are fragmented assemblies based on short reads alone. The addition of long read data massively improves reference quality by resolving repetitive regions. Complete chromosome-scale assemblies anchored with long reads now exist for model organisms like Arabidopsis thaliana and Caenorhabditis elegans. In humans, the addition of Nanopore reads to the Human Pangenome Reference Consortium's integrative approach resulted in a human pangenome assembly with far fewer gaps and misassemblies compared to previous references. Long reads are revolutionizing our understanding of structural variation in populations and facilitating more accurate clinical interpretation.

Going global with portable sequencers

Portable long read sequencing devices have enabled genomic research and applications to take place virtually anywhere. The portable MinION sequencer from Oxford Nanopore weighs only about as much as a smartphone and sequences DNA directly without needing complex robotics. This has allowed long read sequencing to be performed in remote locations and low resource settings for the first time. MinIONs have been used in projects as diverse as Ebola surveillance, sequencing at the International Space Station, characterizing outbreak strains in real-time, and sequencing ancient DNA in Siberia. Portable sequencers empower local scientists and physicians around the world with genomic technologies that were previously only available in big labs. This global dissemination will drive innovation tailored to local health challenges.

Nanopores make transcripts tangible

Direct RNA sequencing with Nanopore protocols produces full-length transcript sequences without the need for cDNA conversion or PCR amplification. This represents a huge step forward for transcriptomics. For the first time, the complexity of eukaryotic transcriptomes, including alterative splicing, modifications, and isoform diversity, can be comprehensively understood at a whole new level. Nanopore direct RNA sequencing is accelerating biomarker and therapeutic target discovery by elucidating cellular responses at single-cell resolution. Regulated alternative splicing alterations have been uncovered in disease states like cancer that would be difficult to detect by other methods. Direct RNA sequencing also facilitates sensitive detection of viral quasispecies and transcriptome profiling in clinically relevant sample types difficult to analyze previously such as liquid biopsies. The ability to characterize full-length RNA transcripts opens exciting new avenues of discovery.

Democratizing genomics

By lowering both capital costs and complexity, long read technologies from Nanopore and PacBio are democratizing genomic research and applications. Benchtop sequencers costing under $10,000 USD now provide throughput sufficient for many projects. Easy-to-use, rapid sequencing chemistries require little hands-on time. Automated, cloud-based analysis and data storage keeps downstream bioinformatics accessible for non-experts. Grassroots 'citizen science' initiatives are using portable Nanopore sequencers to characterize environmental microbiomes and track antibiotic resistance worldwide. Crowdfunded projects are also applying long reads to questions in evolutionary and population genomics previously unexplored due to cost prohibitions. Lower barriers to genomic research will empower scientists everywhere to answer questions relevant to their local communities. Overall, long read sequencing technologies are opening up genomic insights worldwide on an unprecedented scale.

Developments in global long read sequencing will revolutionize genomic science in the coming years. By generating complete genomic and transcriptomic information in a single read, long reads overcome many previous limitations. Their applications in human healthcare, agriculture, evolutionary biology and more are providing insights that were not possible before. Portable sequencers are disseminating these technologies worldwide. Democratization of long read platforms through lower costs will empower researchers globally. Overall, long reads are poised to transform life sciences research on a truly global scale, accelerating discoveries in both large laboratories and more grassroots settings for the benefit of all.
