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: Comparison of parts BBa_K862000 and BBa_K862001 via ONPG assay of Bl21(DE3) UV-irradiated for different times. Both constructs show a strong correlation between the UV-irradiation time and the LacZ activity (as measured by the production of o-nitrophenol).



Fig. 2: X-gal assay of Bl21(DE3) transformed with precA/precB/psulA_LacZ parts (BBa_K862000, BBa_K862001, BBa_K862002) and irradiated for different times. All constructs show a strong positive correlation between UV induction time and coloring of the wells. PrecA-LacZ (BBa_K862000) gives the lowest reporter background expression whereas psulA-LacZ (BBa_K862001) gives the highest overall coloring of the samples.
