A sensitive expression assay was then conducted on the functioning BBa_K3189015 by, growing multiple E. coli BBa_K3189015 transformants in a 96-well plate in varying concentrations of tetracycline labeled in Figure 1. A dark pigment was seen at 100 ng/mL tetracycline, with less colour visible at 50 ng/mL for some of the samples, and no colour visible in the absence of tetracycline. This shows that we have improved BBa_1343002 by introducing BBa_K3189001 upstream to act as its new promoter sequence.
Figure 1: E. coli BL21(DE3) BBa_K3189015 transformants from 11 different colonies grown in LB+tetracycline. The three wells in the top right hand corner are negative controls (E. coli without BBa_K3189015). A dark colour of variable intensity is visible at 100 ng/mL tetracycline for all of the samples.
The construct BBa_K3189015 containing the chromoprotein amilCP (BBa_K1343022) under the control of BBa_K3189001. When the system is induced with 100 ng/mL of tetracycline, a dark blue colour is produced (Figure 2 and Figure 3). This shows BBa_K3189001 is able to function with different reporter proteins other than just gfp.
