Technical note: Preparing samples for PacBio whole genome sequencing for de novo assembly – Collection and storage
Single Molecule, Real-Time (SMRT) Sequencing uses the natural process of DNA replication to sequence long fragments of native DNA. As such, starting with high-quality, high molecular weight (HMW) genomic DNA (gDNA) will result in better sequencing performance across difficult to sequence regions of the genome. To obtain the highest quality, long DNA it is important to start with sample types compatible with HMW DNA extraction methods. This technical note is intended to give general guidance on sample collection, preparation, and storage across a range of commonly encountered sample types used for SMRT Sequencing whole genome projects. It is important to note that all samples and projects are unique and may not be comprehensively addressed in this document.

Technical note — Preparing DNA for PacBio HiFi sequencing – Extraction and quality control
Single Molecule, Real-Time (SMRT) Sequencing uses the natural process of DNA replication to sequence long fragments of native DNA in order to produce highly accurate long reads, or HiFi reads. As such, starting with high-quality, high molecular weight (HMW) genomic DNA (gDNA) will result in longer libraries and better performance during sequencing. This technical note is intended to give recommendations, tips and tricks for the extraction of DNA, as well as assessing and preserving the quality and size of your DNA sample to be used for HiFi sequencing.

Product note — SMRTbell express template prep 2.0 for large-insert libraries
The SMRTbell Express Template Prep Kit 2.0 provides a streamlined, single-tube reaction strategy to generate SMRTbell libraries from 500 bp to >50 kb insert size targets to support large-insert genomic libraries, multiplexed microbial genomes and amplicon sequencing. 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 support SMRTbell library generation in only 4 hours, making complete construction in less than a day. This significantly reduces time to results for generating high-quality genome assemblies to fully characterize SNPs and structural variants. Additional key benefits of this template preparation kit and updated protocol include library generation with as little as 2 to 3 µg input gDNA and flexibility to accommodate and adjust input amount in accordance with the extracted gDNA quality.

Product note — Fast, high-resolution DNA sizing with the fragment analyzer system
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.

Product note — SMRTbell express template prep 2.0 for microbial multiplexing
The SMRTbell Express Template Prep Kit 2.0 provides a streamlined, single-tube reaction strategy to generate SMRTbell libraries from 500 bp to >50 kb insert size targets to support large-insert genomic libraries, multiplexed microbial genomes and amplicon sequencing. 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 obtaining complete microbial genome assemblies with multiplexed sequencing. By using a single-tube, addition-only strategy, the streamlined workflow reduces the number of AMPure clean-up steps. This provides an opportunity to explore automation solutions for high-volume projects, while using as little as 1 ug of input DNA.

Application note — Microbial multiplexing workflow on the Sequel system
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), samples are sheared to approximately 12 kb distribution, ligated with barcoded overhang adapters, pooled at equimolar representation, and sequenced. Demultiplexing of samples is automated, allowing for immediate genome assembly on our SMRT Link analysis software solution.
