Procedural guidelines
•
Minimize freeze-thaw cycles of Oncomine™ Comprehensive Assay Plus panels and the RMC by
aliquoting into low bind tubes as needed for your experiments. Panels can be stored at 4°C for 1
year. Store RMC at –30°C to –10°C.
•
Use good laboratory practices to minimize cross-contamination of products. If possible, perform
PCR setup in an area or room that is free of amplicon contamination. Always change pipette tips
between samples.
•
Use a calibrated thermal cycler.
•
Pipet viscous solutions, such as 5X Ion AmpliSeq™ HiFi Mix, FuPa Reagent, Switch Solution, DNA
Ligase, and panels, slowly and ensure complete mixing by vortexing or pipetting up and down
several times.
•
Arrange samples in alternating columns on the plate for easier pipetting with multichannel pipettes
during purification with the DynaMag™ Side Magnet.
Before you begin
Before each use of the kit
•
Thaw components that contain enzymes—such as 5X Ion AmpliSeq™ HiFi Mix, FuPa Reagent, DNA
Ligase, and 1X Library Amp Mix —on ice, and keep on ice during procedure. All other components,
including primer pools, can be thawed at room temperature. Gently vortex and centrifuge before
use.
•
If there is visible precipitate in the Switch Solution after thawing, vortex or pipet up and down at
room temperature to resuspend.
•
Bring the Agencourt™ AMPure™ XP Reagent to room temperature.
IMPORTANT! Do NOT substitute a Dynabeads
AMPure™ XP Reagent.

Guidelines for RNA isolation, quantification, and input
Guidelines for RNA isolation, quantification, and input
•
We recommend the MagMAX™ FFPE DNA/RNA Ultra Kit (Cat. No. A31881) for isolating RNA.
•
We recommend the Qubit™ RNA HS Assay Kit (Cat. No. Q32855) for quantifying RNA.
•
Treat total RNA with DNase before use.
•
We recommend using 20 ng of total RNA for reverse transcription. Increasing the amount of
total RNA will usually result in higher quality libraries, especially when RNA quality or quantity is
unknown. With high-quality, well-quantified samples, as little as 1 ng total RNA can be used.
•
In general, library yield from high quality RNA is greater than from degraded samples. Library yield
is not indicative of sequencing performance.
Guidelines for DNA isolation, quantification, and input
•
We recommend the MagMAX™ FFPE DNA/RNA Ultra Kit (Cat. No. A31881) for isolating DNA.
•
We recommend the TaqMan™ RNase P Detection Reagents Kit (Cat. No. 4316831) for quantifying
amplifiable human genomic DNA (see Demonstrated Protocol: Sample Quantification for Ion
AmpliSeq™ Library Preparation Using the TaqMan™ RNAse P Detection Reagents Kit (Pub. No.
MAN0007732) available at thermofisher.com).
•
The Qubit™ dsDNA HS Assay Kit (Cat. No. Q32851 or Q32854) can also be used for quantification,
particularly for FFPE DNA, and highly degraded DNA samples.
•
Quantification methods such as spectrophotometry (for example, using a NanoDrop
spectrophotometer) are not recommended, because they are not specific for DNA. Use of these
methods can lead to gross overestimation of the concentration of sample DNA, under-seeding of
the target amplification reaction, low library yields, and poor chip loading.
•
We recommend using 20 ng of DNA for manual library preparation and automated library
preparation. Increasing the amount of DNA results in higher-quality libraries, especially when DNA
quality or quantity is unknown.

RMC in DNA target amplification reactions
Oncomine™ Comprehensive Assay Plus has been developed to support a wide range of biomarkers,
including assessment of microsatellite instability (MSI). MSI arises from defects in the mismatch repair
(MMR) system and is associated with hypermutability of short DNA sequence repeats (microsatellite
locations) throughout the genome.
RMC is composed of in-sample standards that function as internal references in the analysis pipeline to
ensure the robustness of MSI assessment in case of variations in sample preparation or run conditions.
RMC is added to the DNA target amplification reaction.

Remove deaminated bases from FFPE DNA
Sample age, storage conditions, and FFPE preservation methods can lead to significant cytosine
deamination of the isolated DNA. This deamination can result in an artificially high deamination score
when determining the tumor mutational burden result. We have demonstrated that deaminated cytosine
(uracil) bases can be enzymatically removed by treatment with Uracil DNA Glycosylase (UDG).
Note: We recommend treating all samples including FFPE and high quality (for example, commercial
controls or DNA isiolated from cell lines) DNA with UDG to remove deaminated bases before target
amplification.

DNA preparation and amplification
Use the components of the Oncomine™ Comprehensive Assay Plus, DNA, Manual Library Preparation
(Cat. No. A47620) for the following procedures.
RMC in DNA target amplification reactions
Oncomine™ Comprehensive Assay Plus has been developed to support a wide range of biomarkers,
including assessment of microsatellite instability (MSI). MSI arises from defects in the mismatch repair
(MMR) system and is associated with hypermutability of short DNA sequence repeats (microsatellite
locations) throughout the genome.
RMC is composed of in-sample standards that function as internal references in the analysis pipeline to
ensure the robustness of MSI assessment in case of variations in sample preparation or run conditions.
RMC is added to the DNA target amplification reaction.
Remove deaminated bases from FFPE DNA
Sample age, storage conditions, and FFPE preservation methods can lead to significant cytosine
deamination of the isolated DNA. This deamination can result in an artificially high deamination score
when determining the tumor mutational burden result. We have demonstrated that deaminated cytosine
(uracil) bases can be enzymatically removed by treatment with Uracil DNA Glycosylase (UDG). For this
reason, we recommend treating DNA isolated from FFPE samples with UDG to remove deaminated
bases before target amplification.
Chapter 4

Note: We recommend treating all samples including FFPE and high quality (for example, commercial
controls or DNA isiolated from cell lines) DNA with UDG to remove deaminated bases before target

Ligate adapters to the amplicons and purify
When sequencing multiple libraries on a single run, you must ligate a dierent barcode to each library.
DNA and RNA libraries from the same sample also require dierent barcodes.
IonCode™ Barcode Adapters are provided at the appropriate concentration and include forward and
reverse adapters in a single well. No further handling is necessary.
Ion Xpress™ Barcode Adapters require handling and dilution as described in “Ion Xpress™ Barcode
Adapters only: Combine and dilute adapters”.
IMPORTANT! When handling barcoded adapters, be careful to avoid cross contamination by changing
gloves frequently and opening one tube at a time.
Ion Xpress™ Barcode Adapters only: Combine and dilute adapters
For each barcode X selected, prepare a mix of Ion P1 Adapter and Ion Xpress™ Barcode X at a final
dilution of 1:4 for each adapter. Scale volumes as necessary. Use 2 μL of this barcode adapter mix in

The dilution factor is 300 pM/50 pM = 6.
•
Therefore, 10 μL of library that is mixed with 50 μL of Low TE (1:6 dilution) yields
approximately 50 pM.
42
Note:
Good results have been observed with libraries ≤50 pM. Proceed to the next step without further
·
dilution.
Libraries that yield significantly less than 50 pM can be rescued with library amplification. See
·
“Tips” on page 87.

Proceed to “Combine libraries” then template preparation, or store libraries as described below.
STOPPING POINT
Libraries can be stored at 4–8°C for up to 1 month. For longer term, store at
–20°C. We recommend transferring the supernatant to an RNase‑free microcentrifuge tube for
long-term storage. Alternatively, seal the plate with a new MicroAmp™ Clear Adhesive Film for
long-term storage.
Oncomine™ Comprehensive Assay Plus User Guide
Combine libraries
% Reads, % Volume
of Combined Library
When comparing genomic DNA and RNA libraries that are prepared from the same sample, unequal
volumes of libraries can be combined to produce dierent read depths for the paired DNA and RNA
libraries.
•
Combine DNA and RNA library pools from the same samples prepared on an Ion Chef™ Instrument.
Note: Upon completion of the Ion Chef™ Instrument run libraries have already been adjusted to
a final concentration of ~100 pM each and pooled on the Ion Chef™ Instrument. Libraries from
samples A–D are in the Recovery Tube in Position C and samples E–H in Position D of the Ion
AmpliSeq™ Chef Reagents DL8 cartridge.
a.
Combine the DNA library pool with the RNA library pool for a given set of 4 samples at a 90:10
ratio (DNA:RNA—18 µL of DNA library pool + 2 µL of RNA library pool).
Note: This ratio diers from previous Oncomine™ Comprehensive Assay protocols.
IMPORTANT!
The combined DNA and RNA library pools must be from matched Recovery Tubes. For
·
example, combine Position C libraries, do NOT combine sample DNA libraries from Position
C (samples A–D) with sample RNA libraries from Position D (samples E–F) or vice versa.
Each combined library must have a unique barcode.

Dilute the combined (90:10 DNA:RNA) pooled libraries 2‑fold (~50 pM final concentration).
Note: We recommend sequencing up to 4 research samples (one library pool, either samples
A–D or E–H) on a single Ion 550™ Chip.
Combine each uniquely barcoded DNA and RNA library (~50 pM each) from the same sample

About Planned Runs
Planned Runs are digital instructions that are created in Torrent Suite™ Software for controlling the
template preparation and sequencing instruments. Planned Runs contain settings such as number
of flows, kit types, barcodes, sample information, and reference files (if any). Planned Runs are also
used to track samples, chips, and reagents throughout the workflow, from template preparation on
the Ion Chef™ Instrument through sequencing on an Ion S5™ XL Sequencer, Ion GeneStudio™ S5 Plus
Sequencer, or Ion GeneStudio™ S5 Prime Sequencer and subsequent data analysis. Each chip that is
prepared in an Ion Chef™ run requires its own Planned Run.
IMPORTANT! For more information on creating a Planned Run in Torrent Suite

Parameter nameDescription
Main tab
Enable MSI DetectionWhen set to true, this parameter enables detection of MSI markers for the
workflow. These markers can identify a form of genomic instability in the
replication of repetitive DNA. MSI often occurs in tumor cells. It leads to
the appearance of multiple alleles at microsatellite loci, which can be easily
identified.
This parameter is set to True by default in the Oncomine™ Comprehensive
Assay Plus analysis workflows. If you do not want to include MSI results
in an analysis, you can set to the parameter to False. Do not change this
setting in other Oncomine™ analysis workflows.
MSI-High ThresholdThe MSI score above which a sample is considered MSI-High. This score is
reported in analysis results.
MSS ThresholdThe MSI score below which a sample will report MSS in analysis results.

Genomic segmentation analysis
The Ion Reporter™ Software Oncomine™ Comprehensive Assay Plus, DNA analysis workflow utilizes
heterozygous population SNPs covered by the assay to determine the ploidy levels of genomic
segments. The genome is divided into contiguous segments of similar ploidy levels using a circular
binary segmentation (CBS) algorithm. Log odd ratios for variant allele frequency of observed population
SNPs (by TVC) and copy-number (CN) ratios (by CNV pipeline) for each segment are calculated. Log
odd ratio and CN ratios are then used to infer:
•
Tumor cellularity percentage (percentage of tumor cells in the sample)
•
Loss-of-heterozygosity (LOH) for each genomic segment. Segment level LOH events are
intersected with targeted gene boundaries to determine LOH events in selected genes. Segment
level LOH events are also aggregated to determine sample level % LOH.

In Ion AmpliSeq™ assays, Copy Number estimates are made by counting reads for each amplicon,
making adjustments to account for certain types of variability, comparing those read counts to
expected counts for those amplicons in a "normal" sample, and then making further adjustment.
Known sources of variability include pool imbalance (when the assay has more than one pool of
amplicons), total number of reads and per amplicon attributes of GC proportion, and length of the
amplicon insert. In practice, we observe other variability that does not associate with known attributes
yet is systematic. The method that we use trains on many diverse samples, captures systematic eects,
and encodes these into a file (the "baseline").
When augmenting a baseline, new samples are run, the size of each systematic eect encoded in the
baseline is estimated, and a correction is applied to remove the eect. These added samples need not
be normal, and should be diverse so as to capture likely systematic variation.
The following instructions walk you through using the new Variability Correction Information Baseline
(VCIB) CNV baseline, creating a new VCIB CNV baseline, or augmenting an existing VCIB CNV baseline
for Oncomine™ Comprehensive Assay panels.
