Several biobricks from the distribution kit were used during our project. These were retrieved from the kit using the protocols provided by iGEM, transformed into E. coli and isolated in elution buffer NE. We also ordered several constructs from IDT (Table 1). These Biobricks were used to create several new biobricks that were relevant to our project. BBa_K2736000, were created to be used as BRET pair to measure the activity of our customized Tar receptors (BBa_K2736003, BBa_K2736004, and BBa_K2736005). To test whether it was possible to switch ligand binding domains of the Tar receptor and two component receptors we created BBa_K2736002, and BBa_K2736006.
