Applications of BBa_K602013

2011 Osaka

This part was assayed for DNA damage detection ability as follows. E. coli transformed with this part was irradiated with UV light, and then incubated for 2 hours to provide sufficient time for lycopene production. Following that, the lycopene was extracted using acetone. The lycopene concentration was measured by absorbance at 474 nm and regarded as an approximate indicator of promoter activity.

In general, a high background level of lycopene was measured even in the absence of any irradiation. This might be due to basal expression from the SOS promoter which is needed for the SOS genes' rapid response to damage. Therefore, promoter response to UV irradiation was defined as the fractional increase of lycopene production over non-irradiated controls, for each irradiated sample/UV energy dosage.
