You will need a PCR machine and computer. 2. Download the PCR software onto the computer. 3.Thaw the GoTaq Colorless Master Mix at room temperature. Vortex the Master Mix, then spin it briefly in a microcentrifuge to collect the material at the bottom of the tube. 4 . Prepare the following reaction mix on ice: Reagent Volume Template DNA (20 ng) 0.2 µL 10 µM forward primer 1.0 µL 10 µM reverse primer 1.0 µL GoTaq master mix 50.0 µL dH2O 47.8 µL Total Volume 100.0 µL 5. If using a cycler without a heated lid, overlay the reaction mix with 1-2 drops of mineral oil to prevent evaporation during thermal cycling. Centrifuge the reaction mix in a microcentrifuge for 5 seconds. 6. Place the reactions in a thermal cycler that has been preheated to 95 degrees Celsius. Perform PCR. What Occurs In the PCR Machine 1. Denaturation: a 2-minute denaturation at 95 degrees celsius. 2. Annealing: perform the reaction about 5 degrees Celsius below the calculated melting temperature of the primers and increasing the temperature in increments of 1°C to the annealing temperature; this should occur anywhere between 30 seconds and 1 minute. 3. Extension: performed between 72-74 degrees Celsius, extension allows 1 minute for every 1 kb of DNA to be amplified; the suggested time for extension is 5 minutes. 4. Refrigeration: refrigerate the tubes at 4 degrees Celsius for several hours; this will minimize the opportunity for DNA polymerase to continue to be active at higher temperatures. 5. Cycle Number: the optimal amplification is 25-30 cycles, but up to 40 may be performed. DNA Measurement Protocol Research and Development Background on Disease Markers Primer Design Illustration
