Protocol
Thaw the 2X PCR Master Mix at room temperature.Vortex the Master Mix gently, and spin it briefly in a micro-centrifuge to collect the material in the bottom of the tube.
Reaction Set Up:
Assemble reaction components on ice and quickly transfer the reactions to a thermocycler preheated to the denaturation temperature (95 ºC). The recommended reaction volume is 25 µL. Reaction volumes between 10 and 50 µL may be used; scale up/down the reaction components accordingly. Final concentration of the Master Mix in the reaction should be 1X.
