FAQ
Reader questions
Can I use standard PCR tubes instead of 0.2 ml tubes on the Thermo Scientific SimpiAmp block?
It is not recommended, as standard tubes may not fit securely in the gradient block and can lead to uneven heating and inconsistent results.
How do I determine the optimal annealing temperature when using a gradient across 0.2 ml tubes?
Run a series of reactions with a temperature ramp across the block and analyze amplicon yield and specificity by gel electrophoresis or real-time detection.
What maintenance schedule is required to keep the thermal gradient accurate for 0.2 ml tube experiments?
Verify block calibration every six months or after extended heavy use, and clean the block after each run to prevent residue buildup.
Is the Thermo Scientific SimpiAmp system compatible with fast polymerase enzymes for gradient PCR using 0.2 ml tubes?
Yes, the thermal cycler gradient settings are compatible with fast polymerases, but follow the enzyme manufacturer’s recommended ramp and extension profiles.
