Product description
The Applied Biosystems™ VetMAX™ Neospora caninum Detection Kit (Cat. No. NEOSP) enables detection of Neospora caninum in
ruminant tissues by real-time PCR amplification of the Neospora Nc5 gene.
The assay is a single-well real-time PCR in which Neospora and exogenous Internal Positive Control (IPC) targets are amplified and
detected using fluorescent TaqMan®probes. The kit includes:
•3 - Mix Neospora: master mix for optimized duplex real-time PCR amplification of Neospora and IPC targets. It contains primers, TaqMan®
probes, and PCR buffer and enzyme.
•4a -EPC Neospora: nucleic acid template for Nc5 target. It serves as an external positive control for the real-time PCR components, and it
is used to set the threshold cycle (Ct) for evaluating test results.
•5 - IPC: internal positive control that is added to each sample and control at the lysis step of the DNA extraction procedure. It serves as a
control for the DNA purification process, and it is used to monitor for the presence of PCR inhibitors.

Important procedural guidelines
•For each real-time PCR run, include the controls indicated in step 1.
•Thaw amplification reagents in one ice bucket or refrigerated rack and controls and samples in a separate ice bucket or refrigerated rack.
•Keep thawed reagents, controls, and samples cooled (2–8ºC).
•Thoroughly mix the contents of each tube by vortexing, then briefly centrifuge before use.
•Follow “Good laboratory practices for PCR” on page 4 to prevent false positives and contamination of test samples with PCR products.
Input DNA requirements
The assay is performed on DNA extracted from 20 mg of tissue. DNA extraction methods that are validated for use with the
VetMAX™ Neospora caninum Detection Kit are available from technical support upon request. In addition, prepare mock-purified
sample using Nuclease-Free Water as starting material and the same DNA isolation method used for test samples (extraction control).
IMPORTANT! Add 5 µL of 5 - IPC to the lysis solution used for DNA isolation for each sample and extraction control.
Perform real-time PCR
Set up the real-time PCR reactions
1. Dispense 20 µL of 3 - Mix Neospora to the appropriate number of PCR plate wells or strip tubes
2. Add sample or control according to the following table:
Sample type Component Volume per reaction
Sample DNA
5.0 µL
Positive control 4a - EPC Neospora 5.0 µL
Extraction control Mock-purified sample 5.0 µL
Nuclease-Free water
5.0 µL
3. Seal each reaction vessel.

Set up and run the real-time PCR instrument
1. Following the manufacturer’s instructions, set up the real-time PCR run using the following parameters.
•Reaction volume: 25 µL
•Passive reference: ROX™ dye (included in 3 - Mix Neospora).
Note: ROX™ dye must be set up if the thermal cycler is capable of detecting it. Thermal cyclers that do not detect ROX™ dye
may be used without affecting the accuracy of the reading.
•Select detectors and assign TaqMan® probe reporter dyes and quenchers for each well or tube used in the analysis:
Target Reporter Quencher
Neospora
FAM™ dye NFQ (Non-Fluorescent Quencher)
IPC
VIC
™
dye
TAMRA

dye
(1)
(1) TAMRA™ dye must be set up for real-time PCR analysis if the thermal cycler is capable of detecting it. Thermal cyclers that do not detect TAMRA™
dye may be used without affecting the accuracy of the reading.

2. Run the thermal cycler program and collect real-time amplification data during the elongation step (1 minute at 60ºC).
Data analysis
Refer to the recommendations of the thermal cycler manufacturer for raw data analysis.
1. Set thresholds separately for each real-time PCR target.
2. Interpret the results for each control and sample according to the obtained Ct values as indicated in the following sections.
Validation
Refer to the Ct QC values listed in the Certificate of Analysis of the batch used for the test. The run is validated if the following criteria
are met:

(2) The result is invalid due to a non-compliant IPC result.
Handling of non-validated samples
1. Dilute the DNA of non-validated samples 1:10 in 1X TE buffer.
2. Perform real-time PCR analysis with 5 µL of this dilution.
3. If the diluted DNA is positive for Neospora or negative for Neospora with a compliant IPC result, the result is then validated.
4. If the diluted DNA is negative for Neospora with a non-compliant IPC result, the result is still not validated. In this case, repeat
the analysis on a new sample.

Good laboratory practices for PCR
When preparing samples for PCR amplification:
•Wear clean gloves and a clean lab coat (not previously worn while handling amplified products or used during sample preparation).
•Change gloves whenever you suspect that they are contaminated.
•Maintain separate areas and dedicated equipment and supplies for:
•Sample preparation and reaction setup.
•Amplification and analysis of products.
•Do not bring amplified products into the reaction setup area.
•Open and close all sample tubes carefully. Avoid splashing and spraying samples.
•Keep reactions and components capped as much as possible.
•Use a positive-displacement pipettor or aerosol-resistant barrier pipette tips.
•Clean lab benches and equipment periodically with 10% bleach solution or DNAZap™ Solutions (Cat. No. AM9890).
