When this happens, the analysis was set to use ‘Relative Threshold' but the CRT values do not show up in the exported data. (Note: To use ‘Relative Threshold', go to “Analysis Settings”, and under the default Ct Settings tab, choose ‘Relative Threshold' under “Algorithm Settings”.)
To export the data, go to ‘Export' and make sure the ‘Results' section is checked. You will notice that the column header will still say ‘Ct' even if you have CRT in the well table like above. If you export the data but notice that the numbers still correspond to the ‘Ct' values (and not the CRT values), then you will need to use the ‘Load Export Set' button. Just click ‘OK' to the pop-up window. and the changes will be applied. The next time you export, the values should reflect the CRT values.

Sometimes an error can occur when the file is downloaded to the computer. When this occurs you may see an abrupt break in the data. If you see this, you can repair the data by going to Analysis then Analyze from Raw Data. You should then see a fixed plot. Please note that you would need to have at least v1.2 of the QuantStudio 12K Flex software to use this feature. If you do not have this version, or if you do but the error persists, please send your data file to techsupport@thermofisher.com so that we can attempt to recover the data.

The ‘reveal traces' feature for genotyping runs allows you to trace the clusters throughout the PCR process. For some assays you may find better cluster discrimination at, say, cycle 40, as opposed to cycle 50. To use this feature, the amplification data needs to have been collected for the run.
- Go to 'Analysis Settings'.
- Under the default ‘Call Settings' tab, Choose 'Analyze Real-Time Run (?) Data'.
- Click ‘Apply Analysis Settings'.
- Under the Allelic Discrimination Plot, check the box next to ‘Reveal Traces'. You can then move the slide bar to see how the data change with the cycle number.

You will need an oligo sequence with the custom dye but without the quencher molecule. Set up a plate of dye dilutions such as seen in the “Custom Dye Calibration” section of this link:
https://tools.thermofisher.com/content/sfs/manuals/4474347B.pdf
1.Set up a dummy run using the ‘Standard Curve' option. Alter the thermal profile so that it simply ramps to 60 degrees C with a 2 min hold. Ensure that the filters of interest are selected.
2.When the run is complete, export and examine the raw data. Select the concentration to use by finding the dilution that will give you an acceptable signal in the following ranges:
- For a 384-well plate: between 400,000 and 1,200,000
- For a 96-well plate: between 1,400,000 and 4,300,000
3.Create a full plate of the dye using the selected concentration and run the custom dye calibration as normal, using 20 µL.

All the calibration plates can be stored and reused three times for up to 6 months after you first open them, so make sure to return them to their original packaging and return them to -20 degrees C storage until the next use. (Note: Due to the small volumes, calibration array cards cannot be reused. Please discard them after use.) If needed, you can make your own background plate using deionized water. Please follow the directions in the QuantStudio 12K Flex Real-Time PCR System Maintenance and Administration Guide (Appendix C) for more details at http://www.thermofisher.com/content/dam/LifeTech/migration/files/pcr/pdfs.par.4982.file.dat/4470689b.pdf.

The uniformity calibration generates data that allows the software to compensate for the physical effects of the QuantStudio 12K Flex Real-Time PCR System filters using the ROI plate. The normalization calibration generates factors that the software uses when comparing data from multiple QuantStudio instruments within a study. There are 2 normalization plates provided in the calibration kit, one containing FAM/ROX dye and the other with VIC/ROX dye.

Yes. You will need to match all the accessories (heated cover and plate adapter) to the block you have installed. For the QuantStudio 12K Flex system, the 96-Standard and 96-Fast blocks use the same heated cover. The 384-well and TaqMan Array Card block also use the same heated cover. The OpenArray block uses it own separate heated cover.

The issue might be due to the block not being properly seated in the instrument. Please follow the steps below:
If you are running software v1.5.1 and below on the QuantStudio 12K Flex Real-Time PCR instrument and using a 384-well plate, you may reach out to our Specialty Oligos team at Specialty_Oligos@thermofisher.com to request Cy5 dye calibration oligos. Each tube is provided at 800 µL, 0.2 µM. For a 384-well plate at 10 µL/well, you will need to order two tubes, or at 20 µL/well, you will need to order three tubes. Please provide your shipping address to Specialty Oligos and they will provide you with a formal quote.
If you are using a 96-well block, the Cy5 dye plate contained in either 7500 Real Time PCR Systems Spectral Calibration Kit II (Cat. No. 4351151) (Standard, 0.2 mL) or 7500 Fast Real-Time PCR Systems Spectral Calibration Kit II (Cat. No. 4362201 (Fast, 0.1 mL) can be used in place of the Cy5 dye calibration oligos.

The calibration files are stored on the QuantStudio 12K Flex instrument; therefore, when you need to perform a new calibration, you will have to delete the old calibration files. From the instrument console, go to the QuantStudio 12K Flex instrument touch screen and select 'Collect Results'. You should then see a list of files stored on the instrument. Manually select a calibration file such as "Fast-96-cal" and press the 'Delete' button to remove the old calibration file. Occasionally, users cannot delete the file off the instrument and may encounter this error: "Some experiments did not collect results therefore cannot be deleted." For these situations, launch the software, go to 'maintenance', manage files, and download the calibration file. The status of the experiment should be displayed as 'complete'. Next, delete the old calibration file and rerun the calibration.

To perform pre-read and post-read, choose Get Plate IDs and input the setup file either with Genotyping.edt or spf for your runs.
- Check the box for “Include Pre-read” and uncheck “Include Amplification”.
- Edit the file location and the file name and start the run.
- After your pre-read run has ended, you can either keep the run console on to continue with the post-read, or you can close it and perform other pre-read runs.
If you closed the run console and wish to perform the post-read, put the OpenArray in the same position as it was when you did the pre-read and choose Get Plate IDs again. Select the eds file that you had performed pre-read as the setup file and start the run. Note: it is important here that you select the .eds file, NOT the .spf or .edt file.
If you have placed the array at the wrong position, the software will prompt you to select the correct position.
