3.
Determine the location of the failed wells again as in step 1.
Position of failed wells Action
Identical The sample block is contaminated.
Decontaminate the sample block (see page 159).
Reversed The plate is contaminated.
Discard the plate, then perform the calibration using a new
calibration plate.
4.
Use Smar
t Help if the calibration fails after you decontaminate the sample block and replace the
plate (see “Request technical support with Smart Help” on page 172).
Create a background plate (optional)
Whenever possible, use a background plate listed in “Required materials to prepare calibration plates”
on page 90. These plates contain a buer that accurately simulates the reagents used for PCR, and,
therefore, produces high-quality calibration data.
If a background plate is not available, you can create one as described below.
Required materials:
•
MicroAmp
™
optical 96-well reaction plate
•
Optical adhesive cover or optical flat caps
•
Pipettor, 200‐µL (with pipette tips)
•
Powder‐free gloves
•
Safety glasses
•
Deionized water
IMPORTANT! W
ear powder-free gloves while creating the background plate.
1.
Remove a r
eaction plate from its box and place it on a clean, dry surface.
2.
Aliquot 50 µL of deionized water to each well of the reaction plate.
3.
Seal the plate using an optical adhesive cover or optical flat caps.
4.
Use the plate for background calibration.
