After chip analysis on the instrument is complete, the results are stored on the
instrument.
• If you have not removed the chip from the tray, the touchscreen will display
the results after analysis (see “About the results screen” on page 47).
• If you have already removed the chip, the touchscreen will return to the
Main Menu. To view the saved results, touch the
button in the Main
Menu, then touch
Run History
and select from the list of results files.
Note:
If analysis results in a red flag (
) for either the FAM
™
or VIC
™
dye,
inspect the chip for problems and read the chip again.
After a chip has been read:
• You can reread imaged chips, but we recommend storing them in the dark if you
plan to reread them later. We recommend rereading them within 1 hour after the
initial reading, though storing them in the dark may prolong their read life.
• If you read multiple chips in succession, touch the scroll buttons (
/
) to
scroll through the results screens.
• The instrument retains a copy of the imaged chip data that you can access from
the Run History screen.
Note:
The instrument can store approximately 600 experiment files before it begins
purging the files from memory. When the instrument reaches the limit, it replaces the
oldest file exported from the cache with the data from the current run.
Primary analysis
After the QuantStudio
™
3D Digital PCR Instrument images a chip, the instrument
performs an initial evaluation of the raw data to determine its viability. The instrument
identifies the wells within the captured images and performs a quality assessment of
the composite results to determine whether the instrument has collected usable data.
If the data pass the initial quality assessment, the instrument calculates the
concentration of the nucleic acid sequence targeted by the FAM
™
and VIC
™
dye-
labeled probes. The results are reported in copies per µL along with the results of the
quality assessment displayed using colored flags.
