Exp1: PCR debugging[edit]

In this experiment, I'm setting up a number of PCR reactions with different template DNA, batches of primers, dNTPs and Taqs. The purpose is to find out what went wrong in the last three experiments.

Thermocycling protocol:
95C 15min (3min for iTaq reactions) -> 40 cycles of (94C 30S -> 56C 30S -> 72C 1min) -> 72C 3min
