FAQ

Why does the QIAxcel System or QIAxcel Advanced need to be calibrated?

The QIAxcel System or QIAxcel Advanced works on the basis of fluorescence detection technology. Each channel has a separate excitation light source, with its own optical detection. So each gel cartridge channel is different in the fluorescence emission signal collection mode with its own background and/or baseline noise. When you use a new cartridge, calibration (intensity normalization) is necessary to equalize the variations.

FAQ ID -9019
Why is no signal detected in a lane?

First, check that the glass capillaries at the bottom of the cartridge are intact. You should see approximately 1 mm of glass capillary. Second, check that each tube has at least 10 µl sample volume.

Check the capillary is unblocked by performing the gel-droplet test as outlined in Appendix D in the QIAxcel DNA handbook.

Perform a detector test.

If the issue persists, please send data to QIAGEN Technical Service. The instructions for QIAxcel data folder can be found in FAQ ID-9008.  
FAQ -9015
Why do I hear a grinding sound during transportation when first installing the QIAxcel System or QIAxcel Advanced?
When the QIAxcel or QIAxcel Advanced is first installed and the Transport Locking assembly is removed, there is a possibility that the Transport lower stop is hitting the bottom. When the Transport Locking assembly is first removed, it is recommended to slowly pull up on the Transport assembly so that the lower stop is not hitting the bottom (be sure that the power is turned off before the Transport Lock is removed).
FAQ ID -9017
If a different method is used with the QIAxcel System or QIAxcel Advanced, does a new reference marker table need to be created?

Yes, if a different method is used with the QIAxcel System or QIAxcel Advanced, a new reference marker table needs to be created because of different relative migration time.

Please follow the instructions described in the manual and run the DNA marker and the Calibration marker with the new method.

FAQ ID -1857
When running RNA samples using the QIAxcel System or QIAxcel Advanced, are there any special things to consider?

When running RNA samples on the QIAxcel System or QIAxcel Advanced, the standard RNA denaturation process has to be followed prior to running the sample.

  • Add an equal volume of QX RNA Denaturation buffer to your RNA sample and/or QX RNA size Marker.
  • Heat the solution at 70°C for 2 minutes on a heating block or in a PCR machine, then place on ice for 1 minute.
  • Bring the total sample volume to 10 μl using QX RNA Dilution Buffer and mix the solution by gently pipetting up and down a few times.
  • Analyze the samples immediately.
FAQ ID -1842
What to do if alignment marker and samples are migrating too slowly and the upper alignment marker does not appear on the gel- and/or electropherogram view with the QIAxcel System or QIAxcel Advanced?

Make sure the Gel Cartridge has been calibrated with the computer currently connected.  If not, please re-calibrate the Gel Cartridge.

Make sure the cartridge has equilibrated to room temperature (20°–25°C [68°– 77°F]) and stood upright in the cartridge stand for 20 min prior to use. Empty the buffer tray.

Wash the buffer tray in warm water and rinse thoroughly with deionized or reverse-osmosis water. Refill the buffer tray. Perform a control run with the alignment marker and bland samples (10 μl QX DNA Dilution Buffer). The marker bands should now appear within the chosen separation time.

FAQ ID -1833
How can any clogged capillaries be cleared for use with the QIAxcel System and QIAxcel Advanced?

 

Refer to Appendix D of the QIAxcel DNA Handbook for hot water soaking and gel droplet testing.  The handbook can be accessed by going to the Resources tab in the link below:

http://www.qiagen.com/products/catalog/automated-solutions/detection-and-analysis/qiaxcel-dna-kits#

 

 

FAQ ID -1838
Why does an intensity calibration of the gel cartridge for the QIAxcel System and QIAxcel Advanced need to be performed?

The intensity calibration procedure on the QIAxcel System and QIAxcel Advanced is performed to normalize the signal intensities across all 12 channels of the gel cartridge. This corrects for natural intensity reading variations between each capillary in the cartridge. A correction factor is determined and applied for every subsequent run performed with the cartridge.

FAQ ID -1824
Why does the Power LED not function with the QIAxcel or QIAxcel Advanced instrument plugged in and the main power switch turned on?

Unplug the QIAxcel or QIAxcel Advanced instrument and remove the fuse holder to verify that the fuses are good. If not, please replace the fuses (Cat No. 9241178 Fuse, 4A, 250VAC, QX). If this does not correct the problem, contact QIAGEN Technical Services.

FAQ ID -1851
What should I do if I hear a 'hissing" sound when the QIAxcel System or QIAxcel Advanced is purging?
If you hear a 'hissing" sound when the QIAxcel System or QIAxcel Advanced  is purging, remove the Gel Cartridge and verify that the Cartridge Purge Port label is removed.
FAQ ID -9018
What can be done if lower and upper alignment markers used with the QIAxcel System or QIAxcel Advanced are not aligned correctly?

If lower and upper alignment markers used with the QIAxcel System or QIAxcel Advanced are not aligned correctly, open the channel of the sample that was incorrectly aligned. Check whether any unexpected extra peaks have been detected or if the alignment marker peaks do have any “shoulders” that are detected as separate peaks. Delete any extra peaks if necessary and re-analyze your data.

FAQ ID -1834
If a different DNA size and/or alignment marker is to be used with the QIAxcel System or QIAxcel Advanced, does the Gel Cartridge need to be recalibrated?

The Gel Cartridge does not need to be recalibrated when using a new alignment marker and/or DNA size marker with the QIAxcel System or QIAxcel Advanced. Calibration is required only once, i.e. when the first cartridge is run or when the cartridge is used on a different QIAxcel system than the one it has been calibrated on, or when using a different PC than the one used to calibrate initially.

FAQ ID -1858
What is the QIAxcel Advanced System?

The revolutionary QIAxcel Advanced System replaces traditional, labor-intensive gel analysis of DNA and RNA.

  • Rapid analysis of up to 96 samples without manual intervention
  • Safety and convenience with ready-to-use gel cartridges

See:  http://www.qiagen.com/Knowledge-and-Support/Videos-and-Virtual-Demos/Assay-Demos/QIAxcelAdvancedDemo/  for a virtual demonstration of the special software, features, and applications of the QIAxcel Advanced System.

 

FAQ ID -2650
Why do DNA samples appear in only a few channels when the alignment marker is working using the QIAxcel System or QIAxcel Advanced?

The working alignment marker is an indication that the cartridge channel is working well. DNA samples that do not appear in all channels of the QIAxcel System or QIAxcel Advanced may be caused by:

  1. Low sample volume (< 10 ul). The minimum required sample volume is 10 ul. 
  2. Trapped air bubble in the well. The air bubble must be removed. 
  3. High salt concentration in the sample. Dilute the sample with the QX DNA or RNA dilution buffer and rerun the sample.
FAQ ID -1844
Why are bands compacted together on the gel image

Check that the lower and upper alignment markers are detected correctly, and that the threshold is set properly.

If the issue persists, please send data to QIAGEN Technical Service. The instructions for QIAxcel data folder can be found in FAQ ID-9008.
FAQ ID -9015
Why are there no peaks in all channels during a run with the QIAxcel System or QIAxcel Advanced??

Verify that the Cartridge Purge Port label is removed. If it has been removed, verify that the alignment marker and samples are in the appropriate locations in the Buffer Tray and the 96-well Sample Tray used with the QIAxcel System or QIAxcel Advanced?.

FAQ ID -1847
Why is the alignment marker for the 1.8 kb fragment not visible when using the 25 bp/1.8 kb DNA Size Marker together with the 15 bp/400 bp marker on the QIAxcel System and QIAxcel Advanced?

When using this specific marker combination with the QIAxcel System or QIAxcel Advanced, i.e. for STR analysis, the 1.8 kb fragment lies outside of the range of detectable fragments and does not show up on the electropherogram and/or the gel view image.

 

FAQ ID -1835
When should the N2 bottle used with the QIAxcel Advanced System be changed?

N2 cylinders on the QIAxcel Advanced should be changed when one or both low pressure warnings are shown in the "Status Information" panel.

The left panel of the screen in the "Process" environment is called the "Status Information" panel.  

"Pressure 1" status: OK/Low. OK indicates adequate pressure for the sample run. LOW indicates that the N2 pressure is sufficient for the current sample run; however, the N2 cylinder should be replaced once the run has finished.

"Pressure 2" status: OK/Low. OK indicates adequate pressure for the sample run. LOW indicates that the N2 pressure is insufficient for the current sample run and the analysis will not be performed. The N2 cylinder should be replaced.

FAQ ID -3001
How often should the solutions in the Buffer Tray for the QIAxcel System or QIAxcel Advanced be replaced?

The solutions used with the QIAxcel System or QIAxcel Advanced should not have to be changed for the life of the Gel Cartridge (based on the number of runs).  However, if any contamination is suspected, the Buffer Tray should be cleaned and the buffers should be changed immediately.

FAQ ID -1840
How can drying out of the gel cartridge tips used on the QIAxcel System and QIAxcel Advanced be prevented?

If the gel cartridge tips for the QIAxcel System and QIAxcel Advanced are in contact with air, the tips will dry out. There are 3 ways of preventing the tips from drying.

FAQ ID - 3983

I’m getting the low pressure error on a brand new nitrogen cylinder — why?

The BioCalculator (version 3.2.05) and ScreenGel software have a feature to close the pressure valve after the software is idled for more than 30 minutes. To re-open the pressure valve, execute a command with the software, such as move the buffer tray, unlatch and latch the cartridge; alternatively, you can also exit the software and re-launch it. Also see FAQ ID 3001.

FAQ -9011
What are the common causes of low signal?

The sample DNA concentration might be too low. You can increase sample injection time.

A very strong sample in the same run can cause the threshold to be set too high. As a result, the signal from weaker samples is below this threshold. Try diluting the sample with high concentration with the QX dilution buffer.

High salt concentration in the samples, such as restriction enzyme digested DNA, can interfere with sample injection. Try reducing the salt concentration by diluting such samples with the QX dilution buffer.

If the issue persists, please send data files to QIAGEN Technical Services. See  <a href="/knowledge-and-support/faq/?ID=71818D37-21EF-40B0-BA30-6C8CC8CA82B9"><b>Where are the QIAxcel data stored</a></b>.

FAQ -9013
Why are PCR bands relatively weak and "smearing" but the alignment marker bands are sharp when running samples on the QIAxcel System and QIAxcel Advanced?

High or very low salt concentration could lead to the described appearance when running samples on the QIAxcel System and QIAxcel Advanced. Make sure QX DNA Dilution buffer has been used to dilute your samples. Dilute your samples 1:2 in QX DNA Dilution buffer and re-analyze.
