GFP reporter protein under the control of the J23100 constitutive promoter and LexA 2 operator

This part is a DNA damage reporter. See experience part for more Experimental details.

The Northwestern 2019 iGEM team provided novel characterization data to part BBa_K079050. The 2008 Bologna Team reported their part was unable to be induced by UV light. However, after exposing it to various doses of UV-C (0 J/m^2, 50 J/m^2, and 125 J/m^2), we found that their part showed different responses for different amounts of UV exposure. Specifically, the rate of decrease in Fluorescence/OD is significantly different between each exposure time, providing evidence that this part may actually be able to differentiate between different UV doses, just not in the way it was originally designed for (Figures 3 and 4). Fluorescence measurements were taken every 3 minutes immediately after exposure in a 96-well plate reader for 3 hours.
