Summary
The aim of our project is to create a device to detect Sexually Transmitted Infections (STIs). To that end, we have created three series of BioBricks that enabled us to investigate and characterize the function of different pieces of our self-test.
Characterization of pTAC promoter
Using synthetic biology principles, we have created a self-diagnostic device to detect several Sexually Transmitted Infections (STIs), starting with two major health threats, the Human Immunodeficiency Virus (HIV) and the Hepatitis B Virus (HBV), as an alternative to sampling and laboratory testing.
BBa_K1934040: RFP under control of pTAC promoter
This composite part contains the coding sequence of the RFP reporter gene downstream of pTAC and strong RBS sequences.
BBa_K1934050: CFP under control of pTAC promoter.
This composite part contains the coding sequence of the CFP reporter gene downstream of pTAC and strong RBS sequences.
One of the targets: HIV reverse transcriptase
The objective of our project is to detect some Sexually Transmitted Infections (STIs) and especially, HIV with the HIV reverse transcriptase and HBV with its surface antigen HBsAg. In order to test our detection device, we created two composite parts which contain the coding sequences of p51 and p66 subunits of HIV reverse transcriptase respectively.
BBa_K1934060: p51 subunit of HIV reverse transcriptase.
This composite part contains the coding sequence of the p51 subunit under the control of T7 promoter, a RBS and a T7 terminator.
BBa_K1934061: p66 subunit of HIV reverse transcriptase.
This composite part contains the coding sequence of the p66 subunit under the control of T7 promoter, a RBS and a T7 terminator.
The anchor: streptavidin chimeric protein
As an anchor, we chose to use the streptavidin protein combined with one or two cellulose binding domain(s) in order to be easily fixed onto a cellulose paper.
BBa_K1934020: Streptavidin with Cellulose Binding Domains (CBDs).
This composite part contains the coding sequence of the streptavidin protein combined with two CBDs, which corresponds to the Stanford-Brown 2014 iGEM team part (BBa_K1499004) , under the control of a pTAC promoter, a strong RBS and a bidirectional terminator.
BBa_K1934000: RFP with Cellulose Binding Domains (CBDs)
To verify the efficacy of the CBDs for binding to the cellulose, we created this composite part in which the coding sequences for two different CBDs were fused respectively upstream and downstream of the coding sequence for RFP.
BBa_K1934030: Streptavidin with CBD-CipA (Cellulosomal scaffolding protein A)
In order to test another type of CBDs, we created this composite part which presents the coding sequence of streptavidin followed by the coding sequence of CBD-CipA (Cellulosomal scaffolding protein A) protein. We have submitted this part to the “Best new composite part” special prize.
