Part:BBa_K2638400
Combination of BBa_K2638500 + BBa_K2638560
To identifiy the optimal strength of the gene knock-down through our RNAi / siRNA vectors (BBa_), we tested different promoters and RBS combinations for the expression of the RNAi/siRNA system.
To test the expression strength of our promoter-RBS combination, we constructed this part.
We integrated an eCFP (BBa_) under the control of a promoter from the Anderson collection, a synthetic RBS and two terminators (BBa_) in the pSB1C3 backbone. This expression unit is used as a reference.
To test the expression strength of our promoter-RBS combination a second reporter gene (mRFP BBa_) under control of the target promoter-RBS combination was integrated between the pSB1C3 prefix and suffix.
With the combination of the reporter gene in the backbone and the gene of interest integrated between the pSB1C3 prefix and suffix, the expression strength of the different promoter-RBS combinations can be normalized to the certain expression of the reporter gene in the backbone.
The detection of the differential expression strength of the different promoter-RBS combinations can be calculated through the ration of the fluorescence signals at 608 nm and 485 nm.
