LAB Experiment
In our genetic bi-stable, the amount of molecules produced to switch the system from the two possible steady state is ruled by LacI and TetR protein. The production of LacI molecules by UV induction can be tested replacing the LacI gene by GFP, so it is possible to have a relation of the strength of LacI synthesis measuring the value of its fluorescence. BBa_K079049 and BBa_K079050 are two new construct submitted to the registry by Bologna’s Igem Team 2008. These UV test circuits can be presented schematically by the following sequence:
- Promoter Constitutive Family: BBa_J23118 (1429 strength ) or BBa_23100 (2547 strength);
- LexA Operator Site Binding (K079040 ) ;
- Rbs with Green fluorescence Protein LVA and Terminator (BBa_I763020)
In order to generate the induction by Uv, a box with UV lamp was realized.
UV Side Effect
In addiction to the germicidal effect UV radiation can also cause erythema (reddening of the skin)
and conjunctivitis (inflammation of the mucous membranes of the eye). Because of this,exist limit
to the exposure[1]that depends by the irradiance of the ultraviolet- lamps(next figure).
