Product information
IMPORTANT! Before using this product, read and understand the information in the
“Safety” appendix in this document.
Product description
The TrueMark™ Prostate Protein Assay kit enables protein expression analysis in
human plasma research samples of ve proteins of interest in prostate cancer
research. The kit includes all reagents, assay probes, and calibrator proteins for
sensitive, specic, and reproducible assessment of protein expression of the
following proteins:
•Human kallikrein 2 (KLK2)
•Prostate secretory protein 94 (PSP94)
•Free prostate-specic antigen (FPSA)
•Total prostate-specic antigen (PSA)
•Growth/differentiation factor 15 (GDF15)
The kit supports a combination of plasma samples and a positive control in a
384-well plate format. The fully automated research workow is compatible with the
Biomek™ FXP and Biomek™ FX instruments.
The TrueMark™ Prostate Protein Assay uses TaqMan™ Protein Assays technology.
The technology combines the sensitive, specic protein-binding capabilities of
antibodies with the quantication capabilities of 5′‑nuclease real-time PCR (see “How
the TrueMark™ Prostate Protein Assay works” on page 10). TaqMan™ Protein Assays
enable identication and quantication of proteins from initial sample volumes as
small as 2.5 µL in a single, homogeneous assay format.

Procedure overview
The TrueMark™ Prostate Protein Assay uses TaqMan™ Protein Assays technology.
TaqMan™ Protein Assays use a matched pair of target-specic antibodies, each
conjugated to a DNA oligonucleotide. This technology leverages the sensitivity and
large dynamic range of TaqMan™ real-time PCR. During antibody-analyte binding, the
two DNA oligonucleotides are brought into close proximity, which allows ligation of
the two strands and subsequent creation of the template strand for amplication.
Binding Ligation Real-time PCR
Assay probe B
Assay probe A
Protein target
Cycle number
ΔRn
Assay probes A and B are
introduced to the test and
reference samples. Each
probe consists of a single-
stranded oligonucleotide with
a streptavidin-biotin linkage
to an antibody that
recognizes an epitope of the
target protein.
When combined in solution,
the antibody portions of the
probes bind to the
corresponding epitopes on
the target protein.
A third oligonucleotide
(shown in green) is
introduced that hybridizes to
the oligonucleotide ends of
the assay probes. The hybrid
structure forms preferentially
when the assay probes are
bound to the same protein
and are consequently in
proximity to each other.
DNA ligase then covalently
links the hybridized ends of
the assay probes to form a
continuous DNA molecule
linking the bound antibodies.
The samples undergo real-
time PCR amplication that
specically targets ligated
assay probes.

Procedure overview
10 TrueMark™ Prostate Protein Assay User Guide
The TrueMark™ Prostate Protein Assay workow uses the Biomek™ FXP instrument
for automated setup of binding, ligation, and real-time PCR in the same 384-well
plate. The Ligation-qPCR Master Mix, DNA Ligase, and Master Mix Additive enable
ligation and real-time PCR to be performed sequentially in the sealed plate without
further intervention. The ligation reaction is performed on the ProFlex™ System, then
the 384-well plate is transferred to the QuantStudio™ 12K Flex Instrument for
real‑time PCR. TaqMan™ Protein Concentration Software calculates protein
concentrations from the real-time PCR results that are obtained with the
QuantStudio™ 12K Flex Software.

Methods
Procedural guidelines
•Handle plasma samples according to applicable guidelines and regulations.
•Perform all centrifugation steps as described in the procedure.
•Place each 11‑mm insert in the designated locations of the 24-Position Tube
Rack before placing a tube in the insert. Ensure that the insert is ush with the
rack.
•See the Biomek™ Liquid Handler User’s Manual for proper use of the instrument.
•This procedure is optimized for processing on the Biomek™ FXP and Biomek™ FX
instruments.
•The methods run on the Biomek™ FXP instrument require specied deck layout
and pod names. See “Biomek™ FXP instrument deck layout” on page 45.
•Before starting a run on the Biomek™ FXP instrument, place a biohazardous
waste bag in the tip waste location.
•The Biomek™ FXP instrument must be homed before the rst run of the day. See
“Initialize the Biomek™ FXP instrument” on page 45.
•The Peltiers must be initialized and allowed to reach set temperature before the
start of the procedure. See “Initialize the Biomek™ FXP instrument” on page 45.
•Do not reach across the Biomek™ FXP instrument light curtain while the arms are
in motion. See “Biomek™ FXP instrument light curtain” on page 47.
Day 1—Prepare the Sample Stocks Plate
Before starting this procedure, collect EDTA plasma samples according to your
laboratory methodology and keep frozen until use.
IMPORTANT! Do not dilute samples before use.
1. Thaw plasma test samples and the TrueMark™ Prostate Positive Control as
indicated.
•For small volumes ≤100 µL, thaw the samples on ice or at 4°C until
completely thawed.
•For large volumes of plasma test samples in 4‑mL or 8‑mL tubes, thaw the
samples at room temperature with gentle rotation to allow for even mixing.
Note: User‑dened control samples can be used instead of test samples.
TrueMark™ Prostate Protein Assay User Guide 15
2. Briey vortex test and control samples for 10–15 seconds, then centrifuge the
samples at 1,400 × g for 30 seconds to collect the contents at the bottom of the
tubes.
3. Label the side of a Fast 96‑well plate "Sample Stocks", then place the plate in a
96‑well base on ice.
4. Transfer each test or control sample
to the Sample Stocks Plate,
following the layout shown.
•Test samples—transfer 30 µL
(recommended volume; the
volume can range from a
minimum of 15 µL up to 50 µL).
•TrueMark™ Prostate Positive
Control—transfer 20 µL to each of 2 wells of the Sample Stocks Plate.
Note: A minimum of 1 positive control well should be run on each plate.
Note: Columns 8–12 are not used in the methods. Do not place samples in
those wells.
5. Seal the plate with a MicroAmp™ Clear Adhesive Film.
6. Centrifuge the Sample Stocks Plate at 2,800 × g for 10 minutes at 4°C.
Keep the plate at 4°C or on ice until use.
Proceed to the next step, “Day 1—Set up, then run the Plate 1 binding reaction on
the Biomek™ FXP instrument” on page 16, within 30 minutes.
Do not store or reuse the Sample Stocks Plate.
Day 1—Set up, then run the Plate 1 binding reaction on the
Biomek™ FXP instrument
•Ensure that the Biomek™ FXP instrument is homed and the Peltiers are at set
temperature before the rst run of the day (see “Initialize the Biomek™ FXP
instrument” on page 45).
•Approximately 30 minutes before starting this procedure, thaw the following
reagents at room temperature.
–2 tubes of Probe Buffer
–1 tube of PSP94 Buffer
–1 bottle of Sample Buffer
•After the reagents have thawed, keep at 4°C or on ice until use.
•Store Probes and Calibrators at −20°C until use.
