Note from the differential equations above that the steady-state concentration of free promoter (when d[P]/dt=0) will be independent of the concentration of IPTG introduced into the system. The pre-steady-state maximum concentration of GFP attained will differ, however - this is illustrated on the [[Genetic_Circuits|Genetic Circuits]] and can be explored further using the [[Media:insert link here|matlab simulations]]

Simple Model (1)

More Sophisticated Model(2)

Equilibria

Assumptions:

No intermediary P-IPTG-LacI complex is formed.

We assumed 2 LacI molecules bind to the promoter.

Equations

Qualitative effect of parameters on behaviour
