precA-LacZ-doubleTerminator
This is a part for the precise quantification of UV-radiation or radioactive radiation in E. coli (recA+) strains, i.e. BL21(DE3). It consits of a recA Promoter (part BBa_J22106) fused to a LacZ reporter cloned in front of a double terminator (part BBa_K173004).

Characterisation
This part was characterized during the 2012 HS competition by the Heidelberg LSL team
Fig. 1: ONPG assay of Bl21(DE3) irradiated for different times. Both constructs show a strong correlation between the UV-irradiation time and the LacZ activity (production of o-nitrophenol).
Fig. 2: X-gal assay of Bl21(DE3) transformed with precA/precB/psulA_LacZ parts and irradiated for different times. All constructs show a strong positive correlation between UV induction time and coloring of the wells. PrecA-LacZ gives the lowest reporter background expression whereas psulA-LacZ gives the highest overall coloring of the samples.
