FAQ: How should I set up an amplification reaction using Crimson Taq DNA Polymerase?

We recommend assembling all reaction components on ice and quickly transferring the reactions to a thermocycler preheated to the denaturation temperature (95°C).

Notes: Gently mix the reaction.  Collect all liquid to the bottom of the tube by a quick spin if necessary.  Overlay the sample with mineral oil if using a PCR machine without a heated lid.

Transfer PCR tubes from ice to a PCR machine with the block preheated to 95°C and begin thermocycling:
