Characterization

(Waterloo iGEM 2019)


To characterize our promoter we cloned it upstream of the RBS in BBa_E0240 (RBS-GFP-Term) and compared it's GFP expression with the already well characterized BBa_J23101 promoter in BBa_I20260. To limit the impact of other variables we insured that BBa_I20260 and BBa_E0240 shared the same backbone, RBS and terminator. In addition to characterizing this promoter with respect toBBa_I20260 we also confirmed proper function of this promoter in the pRJPaph-bjGFP plasmid which was used for expression in Bradyrhizobium for our 2019 project.

==Note:== empty DH5alpha was used as a negative control for GFP expression

1. Cell were grown overnight in LB media at 37 degrees

2. The following morning GFP expression was quantified using the Synergy 4 BioTek plate reader.
