Experiment 1: Cosmic 3760 probe preparation
Step 1: Real time PCR for cosmic probe

Primer sequence: forward primer Ap1V4IU and reverse primer Ap2V4
Reaction program:
94c 2min -> 94c 30sec -> 60C 2min -> 72C 1min-> Plate read -> (94c 30sec -> 60C 2min -> 72C 1min)x 22 cycles -> 72C 5min -> 15C hold.
Note: 8 tubes were prepared and ran first to test if the reaction system is working properly.
Result: THe PCR reaction did not work as the curve never shot up. I am suspecting either the Taq enzyme or the 10x buffer is not working, so I will do a comparison to test the hypothesis. Since I ran a PCR reaction with Platium Taq and buffer few weeks ago, and it worked fine. So it will be used as reference.
