Utah State 2015 iGEM Team Use

The Utah State 2015 iGEM Team paired this fluorescent protein with three Lactococcus lactis constitutive promoters and tested function in Escherichia coli. It showed activity relative to the strength of the promoters (see Figure 1).

Applications of BBa_K1365020

This part was used in the composite part BBa_K1365555 for characterization.

The graph shown above helps us to know distribution of the fluorescence in the cells of E.coli with different CP promotor fused to superfoldedGFP-terminator-RBS collection (CP1, CP11, CP29, CP30, CP41, CP44) and J23101 as reference. We used this method to characterize the CP promoter collection that was BioBricked by the Uppsala 2013 team.
