DIAGENODE MYCOPLASMA PNEUMONIAE / CHLAMYDOPHILA PNEUMONIAE REAL-TIME PCR USER MANUAL<br />

Troubleshooting guide<br />

> Nucleic Acid isolation<br />

Refer to the manufacturer’s product insert.<br />

NB:<br />

Perform preventive maintenance of workstations for automated extraction (according to the<br />

manufacturer’s recommendations). Check the expiration date and storage conditions for<br />

solutions provided.<br />

> PCR<br />

The signal detected for the positive <strong>Mycoplasma</strong> <strong>pneumoniae</strong> and <strong>Chlamydophila</strong> <strong>pneumoniae</strong><br />

control, the DNA extraction & inhibition control (DIA-EIC/DNA-050) are negative or weak.<br />

The PCR conditions do not comply with the protocol:<br />

1. Check extraction procedure.<br />

It’s important to select an appropriate extraction procedure. The extraction procedure<br />

must be validated and limit the presence of inhibitory factors.<br />

2. Check PCR reaction set-up.<br />

To obtain a high sensitivity, you must respect volumes described and the master<br />

mixes suggested.<br />

NB:<br />

Check the calibration of pipettes used (according to the manufacturer’s recommendations).<br />

Check the expiration date and storage conditions of master mixes suggested.<br />

3. Check the PCR profile.<br />

To obtain a high sensitivity, respect the protocol adapted to the real-time PCR used.<br />

4. Check dyes selected.<br />

Check and select dyes adapted for each real-time PCR platform.<br />

5. Interpretation of results.<br />

Check the table and select the appropriate channel.<br />

Important note:<br />

Check storage conditions (during and after experiments) and expiration date . These two<br />

conditions highly influence results obtained .<br />

> Real time PCR system<br />

Refer to the manufacturer’s product insert.<br />

NB:<br />

Perform maintenance of the real-time PCR platform (according to the manufacturer’s<br />

recommendations).<br />
