The Targeted Locus Amplification (TLA) Technology from Cergentis enables the targeted, hypothesis-neutral, amplification of any genomic locus of interest over 50 kb using just one primer pair complementary to a short locus-specific sequence. TLA is a strategy to selectively amplify complete loci on the basis of crosslinking physically proximal sequences. Unlike other targeted sequencing methods, TLA works without prior detailed locus information, as one primer pair is sufficient to amplify tens to hundreds of kilobases of DNA surrounding that locus. In a separate application of TLA, the unamplified template can be used for genome-wide phasing and assembly. TLA enables targeted…
Target enrichment capture methods allow scientists to rapidly interrogate important genomic regions of interest for variant discovery, including SNPs, gene isoforms, and structural variation. Custom targeted sequencing panels are important for characterizing heterogeneous, complex diseases and uncovering the genetic basis of inherited traits with more uniform coverage when compared to PCR-based strategies. With the increasing availability of high-quality reference genomes, customized gene panels are readily designed with high specificity to capture genomic regions of interest, thus enabling scientists to expand their research scope from a single individual to larger cohort studies or population-wide investigations. Coupled with PacBio long-read sequencing, these…
The Agilent 5200, 5300, and 5400 Fragment Analyzer instruments are fast, high-resolution benchtop capillary electrophoresis (CE) platforms that utilize proprietary markers to accurately size fragments ranging from 10 to 50 kb. This platform allows important DNA quality checkpoints to be completed in one hour for de novo large-genome sequencing projects and other PacBio applications leveraging multi-kilobase read lengths. The instrument can be used in place of time-consuming QC steps involving pulsed field gel electrophoresis (PFGE), saving time by avoiding multiple overnight gel runs when preparing large-insert SMRTbell libraries. Alternative DNA-sizing instruments cannot accurately resolve large DNA fragments in this range.

With this new formulation, we have increased both the yield and efficiency of SMRTbell library preparation for SMRT Sequencing while further minimizing handling-induced DNA damage to retain the integrity of genomic DNA (gDNA). This product note highlights the key benefits, performance, and resources available for supporting de novo genome sequencing and structural variant detection projects. Our large-insert gDNA protocol has been streamlined to…
Obtaining microbial genomes with the highest accuracy and contiguity is extremely important when exploring the functional impact of genetic and epigenetic variants on a genome-wide scale. A comprehensive view of the bacterial genome, including genes, regulatory regions, IS elements, phage integration sites, and base modifications is vital to understanding key traits such as antibiotic resistance, virulence, and metabolism. SMRT Sequencing provides complete genomes, often assembled into a single contig. Our streamlined microbial multiplexing procedure for the Sequel System, from library preparation to genome assembly, can be completed with less than 8 hours bench time. Starting with high-quality genomic DNA (gDNA),…

Obtaining plant and animal genomes with the highest accuracy and contiguity is extremely important when exploring the functional impact of genetic diversity. A comprehensive view of the genome provides power to capture undetected SNVs, fully intact genes, and regulatory regions embedded in complex structures that fragmented draft genomes often miss. Single Molecule, Real-Time (SMRT) Sequencing has become the gold standard for easy and affordable generation of high-quality de novo genome assemblies of even the most complex plant and animal genomes.
With Single Molecule, Real-Time (SMRT) Sequencing and the Sequel Systems, you can easily and affordably sequence complete transcript isoforms in genes of interest or across the entire transcriptome. The Iso-Seq method allows users to generate full-length cDNA sequences up to 10 kb in length — with no assembly required — to confidently characterize full-length transcript isoforms.
With Single Molecule, Real-Time (SMRT) Sequencing and the Sequel System, you can easily and cost effectively generate highly accurate long reads (HiFi reads, >99% single-molecule accuracy) from genes or regions of interest ranging in size from several hundred base pairs to 20 kb. Target all types of variation across relevant genomic regions, including low complexity regions like repeat expansions, promoters, and flanking regions of transposable elements.
With highly accurate long reads (HiFi reads) from the Sequel II System, powered by Single Molecule, Real-Time (SMRT) Sequencing technology, you can comprehensively detect variants in a human genome. HiFi reads provide high precision and recall for single nucleotide variants (SNVs), indels, structural variants (SVs), and copy number variants (CNVs), including in difficult-to-map repetitive regions.
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.
