20 QX600 Droplet Reader and QX Manager Software, Standard Edition

Chapter 1 Introduction to Droplet Digital PCR
Droplet Digital™ PCR is a digital polymerase chain reaction method based on water-oil emulsion droplet
technology. Droplet Digital PCR™ (ddPCR™) uses a combination of microfluidics and proprietary
surfactant chemistries to divide each sample into water-in-oil droplets. The technology uses reagents andworkflows similar to those used for most standard TaqMan probe-based assays, and provides absolute
quantification of nucleic acid target sequences by counting nucleic acid molecules encapsulated indiscrete, volumetrically defined water-in-oil droplet partitions.
ddPCR is highly effective in the following areas:nAbsolute quantification — ddPCR provides a concentration of target DNA copies per input sample
without the need for running standard curves, making this technique ideal for target DNA
measurements, viral load analysis, and microbial quantification.

n

Genomic alterations such as gene copy number variation (CNV) — CNVs result in too few or
too many dosage-sensitive genes responsible for phenotypic variability, complex behavioral traits,
and disease. ddPCR enables measurement of 1.2x differences in gene copy number.

n

Detection of rare sequences — researchers must amplify single genes in a complex sample, suchas a few tumor cells in a wild-type background. ddPCR is sensitive enough to detect rare mutations orsequences.

nGene expression and microRNA analysis — ddPCR provides stand-alone absolute quantificationof expression levels, especially low-abundance microRNAs, with sensitivity and precision.

n

Next-generation sequencing (NGS) — ddPCR quantifies NGS sample library preparations toincrease sequencing accuracy and reduce run repeats. Validate sequencing results such as single
nucleotide polymorphisms or copy number variations with absolute quantification.

nSingle cell analysis — the high degree (10-fold to 100-fold) of cell-cell variation in gene expression
and genomic content among homogeneous post-mitotic, progenitor, and stem cell populations drives
a need for analysis from single cells. ddPCR enables low copy number quantification and gene
expression of individual cells.

nGenome edit detection — ddPCR enables fast, precise, and cost-effective assessment of HDR(Homology directed repair) and NHEJ (non-homologous end joining) generated by CRISPR-Cas9 orother genome editing tools.

User Guide | 21

Chapter 1 Introduction to Droplet Digital PCR

ddPCR has the following benefits for nucleic acid quantification:n

Unparalleled precision — The massive sample partitioning afforded by ddPCR enables small folddifferences in target DNA sequence between samples to be reliably measured.

nIncreased signal-to-noise ratio — High-copy templates and background are diluted, effectively
enriching template concentration in target-positive partitions. This allows for the sensitive detection ofrare targets and enables a ±10% precision in quantification.

nRemoval of PCR efficiency bias — Error rates are reduced by removing the amplification efficiency
reliance of qPCR, enabling accurate quantification of targets to near zero.

n

Simplified quantification — There is no requirement for a standard curve for absolute
quantification.

ddPCR Workflow
The ddPCR process adheres to the following workflow:nPrepare samples for PCR by combining DNA or RNA with primers, probes dye, and
Bio-Rad ddPCR supermix.

n

A droplet generator fractionates a sample into thousands of nanoliter-sized droplets with target andbackground DNA distributed randomly into the droplets during the partitioning process.

n

Following droplet generation, the droplets are run through a thermal cycler, which performs PCRamplification of the nucleic acid target in each individual droplet.

n

A droplet reader reads each droplet to determine the fraction of positive droplets in the original
sample and uses Poisson statistical formulas to determine the absolute quantity.
Note: Positive droplets containing at least one copy of the target DNA molecule exhibit
increased fluorescence compared to negative droplets.

Chapter 2 About the QX600 Droplet Reader
Using the QX600™ Droplet Reader, you can detect rare DNA target copies, determine copy number
variation, and precisely measure gene expression levels. Applications and uses include:n

Copy number variationnAbsolute quantificationnRare sequence detectionnRare mutant detectionn

Next generation sequencing (NGS) library quantificationn

NGS sample preparationn

Viral load determination, including SARS-CoV-2 assaysn

GMO detectionnmRNA analysisnContaminant testingnGene expression analysis and single cell gene expression
analysisnHigh-order multiplexing

Following the droplet generation and thermal cycling processes, the QX600 Droplet Reader collects
binary data for analysis as it singulates the nanoliter-sized droplets in each sample, and then streams
them in single-file past a six-color detector to determine which droplets contain target molecules (positive
reading) and which do not (negative reading).
Note: Your QX600 Droplet Reader performs the post-PCR droplet reading function only. A droplet
generator and a thermal cycler are required to perform a full ddPCR cycle. You can purchase adroplet generator and thermal cycler, as well as associated accessories and consumables, from
Bio-Rad. For information, see Appendix D, Ordering Information.
The QX600 Droplet Reader detects multiple targets in six fluorescent dyes using three interrogation
points across defined spectrums. The first interrogation point detects targets in FAM or EvaGreen® andHEX or VIC, the second in Cy5 and Cy5.5, and the third in ROX and ATTO 590.
Important: Use only the dyes listed above (FAM or EvaGreen®, HEX or VIC, Cy5, Cy5.5, ROX, and
ATTO 590).

Experiment Types
QX Manager Software offers the experiment types described in Table 18, each enabling different assay
options and analysis tools. You can assign multiple experiment types across the plate, but you can assign
only one experiment type to each well.
Table 18. Experiment types

Type

Description

Direct

DQ uses absolute quantification to determine the concentration (copies/μl) of target

quantification

DNA copies in a sample. DQ measures the number of positive and negative droplets(DQ)

for each target in a well based on their fluorescence amplitude, and uses a Poisson
algorithm to calculate the starting concentration of each target DNA molecule.
Note: The ABS experiment type created in QuantaSoft Software versions 1.4
through 1.7 is automatically mapped into the software as a DQ experiment type.

Copy number

CNV determines concentration and calculates the copy number of an unknown (CNV)

variation (CNV)target relative to a known reference or references within the same well.

Mutation

MUT determines concentration and calculates the fractional abundance of andetection (MUT)

unknown mutant present at a low frequency in a wild-type background.

Rare event

RED determines the concentration of a known mutant or a rare target species relative

detection (RED)to a given reference species within a large pool of background DNA.

Drop-off (DOF)

DOF determines absolute quantification of targets for assays designed to detect nonwild type sequences, such as indels and genome edits; DOF is designed to support anassay strategy where one probe counts all alleles and one “drop-off” probe sits on topof a predicted cut site or mutation site.

Gene expression

GEX determines concentration (as with DQ) and calculates relative expression levels(GEX)of an unknown target relative to a known reference or references within the same well.

Residual DNA

RDQ provides a precise method for residual host cell DNA quantification.

quantification

Note: Users can enter a conversion factor (1/C-value) for a given genome(RDQ)(human, mouse, etc.) to calculate the mass for a well based on the number ofcopies measured, up to three decimals. The software displays the result in pg/ulof the ddPCR well in the Molecular Weight column of the Data Table. Starting
sample concentration can then be back-calculated based on dilution factor.

Sample Descriptions
QX Manager Software allows you to enter descriptive words or phrases for your sample in up to four fields
per well. Descriptors can include information such as research type, dilution factors, and so forth.
Tip: Only the information from the first field appears in the Plate Editor layout. However, you can see
entries in the second, third, and fourth fields in the Well Data table, or you can pause on a well to
display a tool tip, as shown in the following graphic.

Sample Types
You can assign multiple sample types within the plate, but you can assign only one sample type to eachwell.
QX Manager Software provides four sample types for selection:nUnknownn

NTC (no template control)n

Pos Ctrl (positive control) where one or more targets are expectedn

Neg Ctrl (negative control), where no response is expected

Important: Beginning in v1.2, QX Manager Software can automatically calculate thresholds for
positive control wells, but you must select Pos Ctrl from the Sample Type dropdown list. You canselect Pos Ctrl during plate setup or in the Analysis module after the run is finished.

Chapter 7 Data Analysis Module Overview
As the instrument reads droplets in each well, the QX600 Droplet Reader collects raw data. At the end ofeach run, QX Manager Software uses the raw data to produce a data file, which contains analysis
information based on the number of positive and negative droplets identified for each target in eachsample. The fraction of positive droplets is fit to a Poisson algorithm to determine the starting
concentration of the target DNA molecule in units of copies/µl input.
This section summarizes the analysis functionality, and also describes the general options governing yourchart displays. More detailed information, including specific information and uses for each analysis
window, as well as information on data calculations, is contained in Chapter 8, Data Analysis
Methodology.
When you select the Data Analysis tab, you can access the Analysis module and the Gene Study module.

Amplitude Charts
Amplitude charts illustrate the droplets by degree of dye fluorescence. QX Manager Software displays

Data Visualization Charts
Data visualization charts show calculations based on positive droplet concentrations. QX Manager
Software counts the number of positive and negative droplets for each fluorophore in each sample, andthen fits the fraction of positive droplets to a Poisson algorithm to determine the starting concentration of
the target DNA molecule in units of copies/µl input in the following analysis windows:nConcentrationn

Fractional Abundance

When you open the analysis data file in QX Manager Software and select one or more wells in the grid,
the software plots each calculated Poisson distribution average as a data point in the grid. You can pause
on the data point to see the high, median, and low numbers.
Note: You can display the data using a confidence level of either 68% or 95% (default setting).

Event Counts
Event counts record the number of droplets in which the target was found (positive) and was not found(negative). The Event Counts tab shows a bar chart view of the number of positive, negative, and total
droplets for each of the targets in each of the selected wells.

Notes:
Copy Number analysis involves determining the number of copies of a given target DNA sequence ascompared to an invariant reference DNA sequence. Use the CNV analysis to determine structuralvariations, such as ploidy changes (addition or deletion of chromosomes), deletions (missing partial
chromosomes) or duplications (repeated target sequences) in the genome.
The ability to discriminate between consecutive CN states has been a technical challenge in copy number
assessment. Fundamentally, as CN state increases, the percentage difference in target genomic material
between states decreases. For example, for a given target locus, a CN of 3 is 50% more abundant inconcentration per genome than a CN of 2, while a CN of 5 is only 25% more abundant per genome than a
CN of 4, and so on.
Due to the massive partitioning of the reaction across up to 20,000 droplets per well, and the absolutenature and precision of the ddPCR concentration measurement, ddPCR CNV analysis enables thequantitative discrimination required to resolve consecutive copy number states beyond CN 3. For
example, a 20% difference in target concentration between a CN 5 versus CN 6 sample can be
reproducibly resolved using ddPCR. This discrimination is both a function of concentration differences
between consecutive CN states, as well as the amount of DNA assayed per well.

Drop-Off Probe in FAM

NHEJ Probe = HEX and Reference Probe =FAM

NHEJ Probe = FAM and Reference Probe =HEX

This type allows three groups of two targets per well; Group 1, shown by default, with 1 target in FAM and
HEX (reference), and 1 target in FAM or HEX (unknown). You can add a second group with 1 target in

Viewing and Adjusting Results
To view and adjust results
1.

Click the 2D Amplitude tab.
All droplets are unclassified by default and are colored red. Only the Threshold Cluster mode isavailable for setting thresholds in Advanced Classification experiments in the 2D plot.

2.

Use one of the Threshold Cluster mode tools (box, circle or freehand) to assign droplet clusters totargets.
When you select a droplet cluster, a cluster assignment box appears.

3.

Select a radio button to identify the composition of the cluster.
For example, if the cluster is composed of positive droplets for Target-2, select the positive radio
button for Target-2 and the negative radio buttons for the remainder.
Important: For calculations to occur, you must have at least one positive cluster for each target,
as well as the assigned negative cluster.
Note: The software sets aside unassigned for calculation purposes. If you are unsure ofdroplet/cluster composition, leave it unassigned (red).
You can view the concentration results in the data table and in the Concentration tab.
If one of your samples was identified as a Reference under AssayType, you can view a ratio ofconcentration for unknown versus reference in the Ratio tab.
