After three minutes of denaturation at 94°C, PCR was performed as follows: 30 cycles of denaturation at 94°C (one minute), annealing at 50°C (1.5 minutes), extension at 72°C (two minutes), final extension at 72°C for 10 minutes (human COX-1, COX-2); 32 cycles of denaturation at 94°C (15 seconds), annealing at 60°C (15 seconds), extension at 72°C (one minute), final extension at 72°C for seven minutes (mouse COX-1); 35 cycles of denaturation at 94°C (15 seconds), annealing at 55°C (15 seconds), extension at 72°C (one minute), final extension at 72°C for seven minutes (mouse COX-2).
