precB-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 recB Promoter (part BBa_K862003) fused to a LacZ reporter cloned in front of a double terminator (part BBa_K173004).

Fig. 1: X-gal assay of Bl21(DE3) transformed with precA/precB/psulA_LacZ parts (BBa_K862000, BBa_K862001, BBa_K862002) and UV-irradiated for different times. All constructs show a strong positive correlation between 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.
