switch device(LTT gfp)for our bio-compass

We use this device as a part of a switch device designed for our bio-compass. It can help us screen out the possible path way which include the start point, terminal point, and the particular intermediate nodes(such as the museum(No.5 node)in our story).It has a LTT Promoter,with elements of the tet, lac, they will compose as a device and is responsive to the commonly used inducers IPTG and aTc, producing GFP as an output signal.If this device and tetR(BBa_K1341003)&lacI(BBa_K1341002)successful inserted in the path way by using the typically enzyme site. It will drive expression of green fluorescent protein (GFP). This characteristic will help us to screen out the possible way we want to find.PS: We build a measurement system to test the screen functional about this device in our project(BBa_K1341001).

model

The x and y axes form a grid of 36 pairs of inducer concentrations. The concentrations tested were 0, 1, 10, 50,

100, and 200 ng/mL for aTC and 0, 0.001, 0.002, 0.005,0.010, 0.100, and 1.000mM for IPTG behavior is depicted 6 h after induction.

The plotted model values are the means of 1000 independent stochastic kinetic simulations, the source and the reference are in the design page.

characterizationc

Conditions are ±100 ng/mL aTc and ±1mM IPTG, e.g., ± refers to 100 ng/mL aTc and 1mM IPTG. This panel depicts an LTT promoter design, where the single lac operator site has been moved upstream of the −35 sequence. In this case, LacI is no longer able to entirely suppress transcription and an intermediate level of induction (leakiness) occurs at conditions of high aTc but no IPTG. All data is obtained 6 h after induction.
