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…
A high-quality reference genome is an essential tool for studies of plant and animal genomics. PacBio Single Molecule, Real-Time (SMRT) Sequencing generates long reads with uniform coverage and high consensus accuracy, making it a powerful technology for de novo genome assembly. PacBio is the core technology for many large genome initiatives, however, relatively high DNA input requirements (5 µg for standard library protocol) have placed PacBio out of reach for many projects on small, non-inbred organisms that may have lower DNA content. Here we present high-quality de novo genome assemblies from single invertebrate individuals for two different species: the Anopheles…
A high-quality reference genome is an essential tool for studying the genetics of traits and disease, organismal, comparative and conservation biology, and population genomics. PacBio Single Molecule, Real-Time (SMRT) Sequencing generates long reads with uniform coverage and high consensus accuracy, making it a powerful technology for de novo genome assembly. Improvements in throughput and concomitant reductions in cost have made PacBio an attractive core technology for many large genome initiatives. However, relatively high DNA input requirements (3 µg for standard library protocol) have placed PacBio out of reach for many projects on small organisms that may have lower DNA content…
