FAQ

The nucleotides can only be ordered as part of the PyroMark Gold Reagents which also contain enzyme and substrate mix.

FAQ ID -2827

PyroMark Gold Q24 reagent and the PyroQ24 Advanced reagent can only be used on the intended instrument model. The chemistry in the PyroMark Q24 Advanced reagent has been improved. Using PyroMark Q24 reagent on a PyroMark Q24 Advanced instrument can lead to much lower peaks; while using PyroMark Q24 Advanced reagent on a PyroMark Q24 instrument can result in increased background and running out of enzyme and substrate prematurely.

FAQ ID -9070

All new assays have to be validated by the user. Interaction between primers or loops formed on single-strangled DNA can serve as priming sites for base incorporation by DNA polymerase. The following controls should be included when an assay is analyzed for the first time:

1. PCR without template DNA —shows if the primers interact to give a background signal in Pyrosequencing reactions

2. PCR with template DNA but with no sequencing primer — shows if the template can loop back on itself and give a background signal in Pyrosequencing reactions

3. Sequencing primer without any PCR product — shows if the sequencing primer can form duplexes or hairpins and give background signal in Pyrosequencing reactions

4. Biotinylated primer without any PCR product — shows if the biotinylated primer can form duplexes or hairpins and give background signal in Pyrosequencing reactions

5. Sequencing primer and biotinylated primer together without PCR product —shows if the sequencing primer and the biotinylated primer can form duplexes and give background signal in Pyrosequencing reactions

Programs from these controls ought not to show any significant peaks after any nucleotide addition.

When using the PyroMark Q24 v2.0, PyroMark Q24 Advanced v3.0, and PyroMark ID 2.5 software, the Sequence to Analyze can be modified if an unexpected mutation is detected. Enter the Sequence to Analyze that fits the detected mutation and apply the change to re-analyze the data.

When using the PyroMark ID 1.0 and PyroMark MD 1.0 software, the Sequence to Analyze cannot be modified. If an unexpected mutation is detected, you will need to re-run the assay with the new Sequence to Analyze.

FAQ ID -9045

The PyroMark Control Oligo is a self-priming oligo which can be used directly in the pyrosequencing reaction without an extra sequencing primer. It was designed for installation of the different PyroMark systems and can be used for general troubleshooting.

It can be used directly for sequencing without previous PCR setup and sample preparation by the vacuum prep tool. By this test, the performance of the instrument can be checked.

In addition, it can also be processed through the vacuum sample preparation to check the performance of this procedure. The control oligo run results in a defined pyrograms with certain peak heights for the individual instruments which are described in the handbook.

The PyroMark Control Oligo can be used on all PyroMark systems including the Q24, Q24 advanced, Q96 ID, and Q96 MD.

FAQ ID -9067

In the case of mistakes and instrument failure, the single stranded DNA can be re-used without re-run PCR. Perform the vacuum prep steps with the streptavidin beads and release them to a new Pyrosequencing plate for a fresh run.

FAQ ID -9063

Cracked waste bottle cap, dirty or wet inline filter between the waste bottle and the vacuum pump, and more than 100-time usage of the vacuum prep probes are the most common causes of slow suction.

Check the integrity of the waste bottle cap. Replace the dirty or wet inline filter. Each system comes with two inline filters. You can order extra inline filters from Millipore with catalog number SLFG05010. Replace the probes after 100 times of usage.

FAQ ID -9041

Mutation assays designed by QIAGEN detect the most common mutations. In addition, QIAGEN provides plug-ins to analyze more mutations and convenient reports for PyroMark KRAS, PyroMark EGFR, and PyroMark BRAF kits. The plug-ins can be obtained by emailing pyro.plugin@qiagen.com

If the mutation cannot be analyzed successfully, please send the original run files to QIAGEN Technical Service for further assistance.

FAQ ID -9047

Blocked reagent cartridge/tips, reagent issue, and incorrect pipetting are the common causes of the substrate peak being absent. Test cartridge/tips before adding reagent. Ensure reagent is pipetted to the correct positions and is collected at the bottom of the cartridge/tips.

If the substrate peak is present, loss of template during the vacuum prep steps, no or incorrect sequencing primer, and camera failure are the common causes. Ensure no residual vacuum pressure before releasing the streptavidin beads and that the correct sequencing primer is used. Perform camera function test, see FAQ ID 9046.

If the issue persists, please send the run files (see FAQ ID 9048) to QIAGEN Technical Service for further assistance.

FAQ ID -9042

The camera function test is intended for the PyroMark Q96 ID, PyroMark Q96 MD/MDA, PSQ MA, and PSQ HS/HSA instruments.

FAQ ID -9064

Insufficient amount of PCR template, loss of streptavidin bead during vacuum prep steps, incorrect instrument method, and incorrect reagent are the common causes of low peak signals.

Check the PCR product with QIAxcel instrument or agarose gel electrophoresis and determine the appropriate amount of PCR product to be used. Perform vacuum prep function test. Determine the vacuum prep station functionality using the PyroMark Control Oligo with and without the vacuum prep steps. Ensure the correct instrument method is used. Refer to Managing PyroMark Instrument Methods. Ensure the correct reagent is used for the specific instrument model.

FAQ ID -9069

Clogged cartridge/tips, and excessive PCR product are the most common causes. Test cartridge/tips before adding reagent.
