Product description
The Applied Biosystems™ VetMAX™ PRRSV EU & NA 2.0 Kit
enables real-time RT-PCR detection of the porcine reproductive
and respiratory syndrome virus (PRRSV). The kit has an updated
design with the ability to detect circulating PRRSV strains. The kit
provides assays and reagents for single-well, real-time RT-PCR
detection of PRRSV EU, PRRSV NA, and internal positive control
(IPC) targets using uorescent hydrolysis probe chemistry.
The kit has been validated for use on RNA extracted from serum,
whole blood, semen, tissue, oral uid, and cell culture
supernatant. A validation report is available by request from your
sales representative or technical specialist.
PRRSV causes signicant losses in the swine industry due to
reproductive disorders, respiratory conditions, and growth
retardation. PRRSV RNA can be detected in blood and semen
24–48 hours after infection. Real-time RT-PCR is the most sensitive
method for detecting PRRSV virus, and is a powerful tool for herd
health management.
The kit includes the following assays and reagents.
•3 – Mix PRRS EU/NA 2.0: Contains primers, probes, buer,
and enzyme for optimized triplex real-time RT-PCR detection
of PRRSV EU, PRRSV NA, and IPC targets.
•4a – EPC PRRS EU/NA 2.0: RNA template with PRRSV EU
and PRRSV NA target sequences. It serves as an external
positive control for the real-time RT-PCR components, and is
used to set validation criteria for test results.
•5 – IPC PRRS: Added to each test and control sample at the
lysis step of the RNA isolation procedure. It serves as an
exogenous internal positive control for the RNA isolation
procedure, and is used to monitor for the presence of PCR
inhibitors.

Procedural guidelines
• Include the following control reactions for each real-time RT-
PCR run.
– Positive control—use 4a – EPC PRRS EU/NA 2.0.
– Extraction control—use mock-puried samples that
have been prepared in the same RNA isolation
procedure as the test samples.
– No-template control (NTC)—use nuclease-free water.
• Follow good laboratory practices to prevent false positives
and contamination of test samples with PCR products (see
“Good laboratory practices for PCR and RT-PCR“ on
page 4).
Guidelines for input RNA
Step, process, or parameter Recommendation
RNA isolation method Applied Biosystems™ MagMAX™
CORE Nucleic Acid Purification
Kit (Cat. No. A32700)
Change to the RNA isolation
method for test samples and
mock-purified samples
Add 4 µL of 5 – IPC PRRS to the
lysis solution used for RNA
isolation.
Preparation of mock-purified
samples, for use in extraction
control PCRs
Prepare at least one mock-
purified sample, using Nuclease-
free Water (not DEPC-Treated) as
the starting material.
Process the mock-purified
sample concurrently in the same
RNA isolation procedure that is
used for test samples.
Before you begin
1. Thaw reagents and samples:
a. Thaw 3 – Mix PRRS EU/NA 2.0 in an ice bucket or
refrigerated rack.
b. Thaw 4a – EPC PRRS EU/NA 2.0, 5 – IPC PRRS, and
RNA samples in a separate ice bucket or refrigerated
rack.
2. Thoroughly mix the contents of each tube by vortexing, then
centrifuge briey to bring the contents to the boom of the
tube.
Store thawed reagents and samples at 2–8°C until use.
Set up the PCR reactions
1. Dispense 12 µL of 3 – Mix PRRS EU/NA 2.0 to the required
number of plate wells or tubes.
2. Add the indicated component for each reaction type.
Reaction type Component Volume per
reaction
Test sample Sample RNA 8.0 µL
Positive control 4a – EPC PRRS EU/NA 2.0 8.0 µL
Extraction control Mock-purified sample 8.0 µL
No-template
control (NTC)
Nuclease-free water 8.0 µL
3. Seal each plate or tube, mix, then centrifuge briey to bring
the contents to the boom of the plate wells or tubes.
Set up and run the real-time PCR instrument
1. Following the manufacturer's instructions, set up the real-
time RT-PCR run using the following parameters.
• Reaction volume: 20 µL
• Passive reference: ROX™ dye (included in 3 – Mix PRRS
EU/NA 2.0)
Note: ROX™ dye must be selected if the instrument is
capable of detecting it. Real-time PCR instruments that
do not detect ROX™ dye may be used without aecting
the accuracy of the reading.

3. Run the appropriate PCR instrument program, collecting
real-time amplication data during the 60°C incubation.
Guidelines for data analysis
• Follow the instrument user guide for raw data analysis.
• Analyze each uorescent dye channel independently.
• Manually set the baseline and threshold seings for data
analysis.
a. For each reporter dye, congure the analysis seings for
manual Ct seing.
b. Save the analysis seings, then export the results.
• Ensure that samples showing amplication in the
normalization data also show amplication in the raw
uorescence data.
• See the Certicate of Analysis for the manufacturing batch of
the kit to validate the run and interpret the results.
Validation criteria
Refer to the CtQC values in the Certicate of Analysis for the manufacturing lot of the kit. The test is validated if the following criteria are
met:
Reaction type PRRSV EU target
(VIC™ dye)
PRRSV NA target
(FAM™ dye)
IPC target
(Cy5™ dye) Interpretation
Positive control Ct = CtQC EU of 4a – EPC
PRRS EU/NA 2.0 ± 3 Ct[1] Ct = CtQC NA of 4a – EPC
PRRS EU/NA 2.0 ± 3 Ct[1] Any value[2] PCR is validated.
Extraction control Ct > 40 Ct > 40 Ct = CtQC 5 – IPC PRRS ± 3 Ct[3] RNA isolation is validated.
No-template control Ct > 40 Ct > 40 Ct > 40 PCR reagents are validated.
[1] See the EPC table in the Certificate of Analysis.
[2] The IPC Ct value of the positive control reaction is not used for validation.
[3] See the IPC table in the Certificate of Analysis.
Interpretation of results
PRRSV EU target
(VIC™ dye)
PRRSV NA target
(FAM™ dye)
IPC target
(Cy5™ dye) Interpretation
Ct < 40 Ct > 40 Any value PRRSV EU is detected.

Retest samples with invalid results
1. Dilute the RNA samples 1:10 in 1X TE buer.
2. Repeat the real-time RT-PCR procedure with 8 µL of the diluted RNA, then interpret the results as follows.
Result Interpretation
The diluted RNA is positive for at least one PRRSV target (NA or EU)
The result is validated.
The diluted RNA is negative for both PRRSV targets (NA and EU), and the IPC result is compliant.
The diluted RNA is negative for both PRRSV targets (NA and EU), but the IPC result is non-compliant. The result is invalid.
3. For diluted samples with invalid results, repeat the RNA isolation procedure on a new aliquot of the original sample lysate.
Good laboratory practices for PCR and RT-PCR
• Wear clean gloves and a clean lab coat.
– Do not wear the same gloves and lab coat that you have
previously used when handling amplied products or
preparing samples.
• Change gloves if you suspect that they are contaminated.
• Maintain separate areas and dedicated equipment and
supplies for:
– Sample preparation and reaction setup.
–Amplication and analysis of products.
• Do not bring amplied products into the reaction setup area.
• Open and close all sample tubes carefully. Avoid splashing or
spraying samples.
• Keep reactions and components capped as much as possible.
• Use a positive-displacement pipeor or aerosol-resistant
barrier pipee tips.
• Clean lab benches and equipment periodically with
10% bleach solution or DNA decontamination solution.
