General Information on Sequel II and Revio Sequencing Systems

The PacBio platform is based on Single Molecule, Real-Time (SMRT) technology. It is ideal for rapidly and cost-effectively generating high-quality whole genome de novo assemblies, full-length transcriptomes, cell type-specific isoforms (MAS-Seq) and long-read targeted amplicon sequences.

The new PacBio Revio system has all the capabilities of the Sequel II but with a higher throughput (up to 3X per SMRT-cell), better accuracy, and shorter run times for a lower cost per base than on the Sequel II.

At this time, Iso-Seq libraries and libraries for fragments shorter than 3 kb (e.g. short amplicons) need to be sequenced on the Sequel II. However, new library preparation kits for the Revio will be available shortly. Note that the yield per SMRT cell is dependent on original material source or organism and cannot be guaranteed.

DNA Extraction Protocols

High-quality, high-molecular-weight genomic DNA is crucial for obtaining long read lengths and optimal sequencing performance. The SMRT library preparation process does not utilize amplification techniques and resulting library molecules are used directly as templates for the sequencing process. The quality of the DNA and RNA starting material will directly impact the extent of sequencing success or failure. Any unrepaired or irreversible DNA damage present in the input material (e.g., interstrand crosslinks, nicks, etc.) or contaminants will result in impaired performance in the system.

Upon receiving your DNA sample, a QC of Qubit, Nanodrop, and Fragment Analyzer is performed to ensure the DNA meets our concentration, purity, and size requirements, respectively.

Ideally, the 260/230 should be within the 2.0-2.2 range, and the 260/280 within 1.8-2.0 range. Initial DNA/RNA quality is critical for a successful run.

If you are submitting 24 or more samples, please submit samples in a 96-well plate and include an Excel file with the sample layout in your order.

If your samples do not meet the requirements in the table below, please contact us to discuss potential options for processing your project.

A Note About Single SMRTcell Projects:
SMRTcell sequencing results depend on the final loading concentration of the library. Due to the nature of the technology, optimal concentrations can vary greatly between libraries and PacBio recommends running 2 titration SMRTcells to find the optimal concentration before running production SMRTcells. With this in mind, please be aware that projects requesting a single SMRTcell may have variable results. In most cases the first SMRTcell performs well and this is not an issue, but sometimes additional sequencing is needed. When this happens, the customer is expected to cover the cost of additional sequencing.
