About the ViiA™ 7 system
The Applied Biosystems™ ViiA™ 7 Real-Time PCR System uses uorescent-based polymerase chain reaction (PCR) reagents to provide:
• Quantitative research detection of target nucleic acid sequences (targets) using real-time analysis.
• Qualitative research detection of targets using post-PCR (endpoint) analysis.
• Qualitative analysis of the PCR product (achieved by melt curve analysis that occurs post-PCR).

Prepare the calibration plate or array card
IMPORTANT! Wear powder-free gloves and safety glasses when you prepare plates or array cards.
1.
Remove the calibration plate or the calibration solution from the freezer, then allow it to thaw to room temperature in the dark
(approximately 5 minutes).
IMPORTANT! Pr
otect the calibration plate and the calibration solution from light. The uorescent dyes in the calibration plate wells
and calibration solutions are photosensitive. Prolonged exposure to light can diminish the uorescence of the dye.
Do not remove the calibration plate from its packaging until you are ready to run it.
2.
epare the calibration plate or array card.
Pr
• To prepare an array card, ll it with calibration solution. For a normalization calibration, ll two cards with separate normalization
solutions.
• To prepare a plate:
a. Remove the plate from its packaging.
IMPORTANT! Do not discar
d the packaging. The plate can be used up to three times if it is stored in its original packaging
sleeve.
b. Vortex the plate for 5 seconds, then centrifuge it for 2 minutes.
Verify that the liquid is at the bottom of each well of
c.
the plate. If not, centrifuge the plate again at a
higher rpm and for a longer period of time.
IMPORTANT! Do not allow the bottom of the plate
to become dirty
. Fluids and other contaminants that
adhere to the bottom of the plate can contaminate
the sample block(s) and cause an abnormally high
background signal.

Guidelines for preparing the reaction plate or array card
Include excess volume in your calculations to provide for loss during reagent transfers.
•
• Use TE buffer or water to dilute the standards and samples.
• Prepare the reagents according to the manufacturer’s instructions.
• Keep the dilutions and assay mix protected from light, in the freezer, until you are ready to use it. Excessive exposure to light may
affect the uorescent probes or dyes.
• To prepare the reactions:
– Mix the master mix thoroughly by swirling the bottle.

– Resuspend the assay mix by vortexing, then centrifuge the tube briey.
– Thaw any frozen samples, resuspend them by vortexing, then centrifuge the tubes briey.
• (Genotyping only) Prepare the reactions for each SNP separately
• Place the reaction plate or array card at 4°C in the dark until you are ready to load it into the instrument.
Prepare the reaction plate
1.
Load the plate with the prepared reactions.
2.
Remove a single optical adhesive lm from the box and bend both end-tabs upward. Hold the lm backing side up.
3.
In one swift movement, peel back the white protective
backing from the center sealing surface. Do not touch the
center sealing surface.
IMPORTANT! Impr
may result in haziness, but it will not affect results. Haziness
disappears when the lm comes into contact with the heated
cover in the instrument.
4.
Holding the lm by the end-tabs, lower the lm onto the
r
eaction plate (adhesive side facing the reaction plate). Be
sure that the lm completely covers all wells of the reaction
plate.
5.
While applying rm pressure, move the applicator slowly
across the lm, horizontally and vertically, to ensure good
contact between the lm and the entire surface of the
reaction plate.
6.
While using the applicator to hold the edge of the lm in
place, grasp one end of the end-tab and pull up and away
sharply. Repeat this step for the other end-tab.
7.
To ensure a tight, evaporation-free seal, repeat step d on
page 15: While applying rm pressure, run the edge of the
applicator along all four sides of the outside border of the
lm.
Note: Optical adhesive lms do not adhere on contact. The
lms require the application of pressure to ensure a tight,
evaporation-free seal.

8.
Inspect the reaction plate to be sure that all wells are sealed.
You should see an imprint of all wells on the surface of the

avoid plates sticking to the instrument after a run.
IMPORTANT! Remove all excess adhesive fr
perimeter of the optical adhesive cover. When the lm is
applied, the glue from the optical adhesive cover can adhere
to the edges of the plate. If the excess glue is not removed,
the plate may adhere to the sample block of the ViiA™ 7
System.
Centrifuge the plate for 2 minutes, then verify that the liquid is
at the bottom of each well of the plate. If not, centrifuge the
plate again at a higher rpm and for a longer period of time.
IMPORTANT! Do not allow the bottom of the plate to become dirty. Fluids and other contaminants that adhere to the bottom of the
plate can contaminate the sample block(s) and cause an abnormally high background signal.

IMPORTANT! Do not try to save time by doing one spin for 2 minutes. The two sets of ramps are important for a good ll into the
array card.

When the second run is nished, open the centrifuge, then check that the uid levels in the r
eservoirs of each array card have
decreased by the same amount. Also, check for the formation of bubbles in all wells, then note possible problems.

If needed, centrifuge the array cards for an extra minute to ll any unlled wells. Do not exceed thr
ee 1‑minute runs or centrifuge the
array card for longer than 1 minute at a time.
8.
Seal the array card(s):
a.
With the carriage (roller assembly) of the Array Card
Staker/Sealer in the Start position, place a lled array
card into the xture with the foil side up so that the ll
reservoirs are the farthest away from the carriage.
b.
Press down on all four corners of the array card to
ensure that it is fully seated within the xture.
c.
Use the two alignment pins in the xture to position the
array card correctly.
Seal the array card by running the carriage slowly over
it. Run the carriage over the array card in one direction
only. Do not apply downward force on the carriage as
you move it forward over the card.
e.
Remove the sealed array card from the xture, then trim
the ll reservoirs from the array card assembly using
scissors. Trim the foil array card so that the edge is even
with the plastic carrier.
IMPORTANT! Completely remove the ll reservoirs
from the array card so that the edge is free of residual
plastic. The plastic from the ll reservoirs that extends
beyond the edge of the card can prevent the array card
from seating properly on the sample block and can
affect amplication.

IMPORTANT! Keep the lled array car
d our of the light. The uorescent dye in the array card is photosensitive. Prolonged exposure to
light can diminish the uorescence of the dye.
