If PCR yield is low when running small reaction volumes with the
Standard ramp rate
✔ If you are using sealing films/mats, shorten the duration of the
denaturation step during cycling. Denaturation times as short as 3–5
seconds may be appropriate. Alternatively, switch to using capped
reaction tubes.
✔ Increase the reaction volume to 50 μl.
✔ Try switching to the Fast ramp rate.
If no actual temperature is displayed during the run
The thermal block unit may not be correctly seated on the instrument.
✔ Check that the unit is installed correctly and reboot the cycler.
If the program does not start
