* Amounts recommended for submission represent quantities needed for one SMRTbell library prep and
includes extra quantity needed for any additional QC and conservative excess. In most cases one library
prep produces enough template for multiple SMRT cells. For insert sizes >1 KB, a magnetic bead loading
protocol is used in the SMRT Cell calculation. Two size-selection protocols for large-insert libraries are
available using either AMPure or BluePippin strategies.
II. Sample requirements for PacBio sequencing
The Pacific Biosciences® library preparation process does not utilize amplification techniques and
resulting library molecules are directly used as templates for the sequencing process. As such, the
quality of the DNA starting material will be directly reflected in the sequencing results. Any irreversible
DNA damage present in the input material (e.g., interstrand crosslinks, etc.) will result in impaired
performance in the system. High-quality, high-molecular-weight genomic DNA is imperative for
obtaining long read lengths and optimal sequencing performance.

III. Important measures impacting DNA quality
To maximize read length and quality, it is essential that your DNA sample:
 Is double-stranded; single-stranded DNA is not compatible with the library preparation process.
 Has not undergone multiple freeze-thaw cycles as they can lead to DNA damage.
 Has not been exposed to high temperatures (e.g.: > 65ºC for 1 hour can cause a detectable
decrease in sequence quality), pH extremes (< 6 or > 9).
 Has an OD260/OD280 ratio of 1.8 to 2.0.
 Does not contain insoluble material.
 Does not contain RNA contamination.
 Has not been exposed to intercalating fluorescent dyes or ultraviolet radiation. SYBR dyes are
not DNA damaging, but do avoid ethidium bromide.
 Does not contain denaturants (e.g., guanidinium salts or phenol) or detergents (e.g., SDS or
Triton X100).
 Does not contain carryover contamination from the original organism/tissue (e.g., heme, humic
acid, polyphenols, etc.)
IV. General guidelines for DNA extraction to maintain high molecular weight and clean DNA
-
Before DNA extraction:
 Avoid incubation in complex or rich media
 Harvesting from several cultures rather than a single, high-density culture during earlyto mid-logarithmic growth phase is preferred.
 Extraction of small volumes is preferred over large volumes to avoid accumulating high
concentrations of potentially inhibiting secondary components.
V. Removal of inhibitors. Some of the genomic DNA extraction methods (see II and IV) – especially fungi
and plant ones – can leave substances in the solution that can inhibit the PacBio sequencing reaction.
PacBio recommends using MoBio PowerClean Pro DNA Clean-Up Kit to remove them. We can do this for
you (please mark the Additional genomic DNA clean-up box) but it results in the loss of some of the
DNA. Choosing this option means we may request additional DNA if there is not enough after clean-up.
