Calibration
Recommended frequency
Background
• Every two years (recommended)
• Background calibration can also be performed, as needed:
– To check for contamination (depends on usage and laboratory
conditions).
– To obtain the most accurate data for the removal of background
fluorescence.
Note:
Performing a Background calibration does
not
invalidate any other
calibration.
Dye
• Every two years (recommended)
• During a Dye calibration, only the dyes on the given spectral calibration
plate are calibrated.
Note:
Performing a Dye calibration for a given dye plate does
not
invalidate
any other calibration.
RNase P instrument
verification
• After installing or moving the instrument
• After performing instrument calibrations
• As needed to confirm instrument performance
Note:
To prepare custom dye plates and to perform custom calibrations, see “Calibrate custom dyes”
.
Calibration descriptions
Calibration description and purpose
Pass Criteria
ROI/Uniformity
• The software captures images for each optical filter.
• The software uses calibration data to map the increase in fluorescence
to the plate wells during subsequent runs and to evaluate well-to-well
consistency of the signals.
The image for each filter
distinguishes all wells of the plate.
Each well in the image is distinct.
Background
• The software captures background images for each optical filter in the
absence of sample and reagent, and it checks that the fluorescence
from each well is below a fluorescence threshold.
• The software uses calibration data to remove background fluorescence
during a run.
Note:
You can also run this calibration to determine if contamination is
related to the sample block or the plate.
The plate images for all filters are free
of abnormal fluorescence.
