Increase (fold)a | |
|---|---|---|---|
| 1 | 25 | ||
| IP2790c/GFP | 3.10 ± 0.6 | 16 ± 8 | 5.16 |
| IP2790.1c/GFP | 3.05 ± 0.55 | 14.5 ± 9.5 | 4.75 |
| IP2515c/GFP | 1.40 ± 0.62 | 7.05 ± 3.05 | 5.05 |

| YPIII(p−)/GFP | 1.39 ± 0.21 | 0.55 ± 0.13 | 0.42 |
a
The n-fold increase was calculated by dividing the average number at 25 h by the average number at 1 h.
b
The numbers represent the averages ± standard deviations from two independent experiments.
