| lhi | 25 | high-copy plasmid number | Estimate | llo | 5 | low-copy plasmid number | Estimate | |
| a | 1% | basic production levels | Estimate | |||||
| Degradation constants | ||||||||
| dlacI | 2.31e-3 [per sec] | degradation of lacI | Ref. [10] | dtetR | 1e-5 [pro sec]/2.31e-3 [per sec] | degradation of tetR |
Ref. [9] Ref. [10] | |
