iGEM TU Eindhoven 2015

We as iGEM TU Eindhoven 2015 used NanoLuc in a BRET sensor together with mNeonGreen. The main goal of our project was to design a universal, modular biosensor that can detect molecules by using aptamers. NanoLuc worked very well for us. We've inserted NanoLuc in a pETDuet-1 vector together with Outer Membrane Protein X (OmpX) and a BsoBI-linker, which is a long and flexible GGSGGS-linker with two BsoBI restriction sites. Several experiments gave very strong results for NanoLuc.

We've characterized NanoLuc by performing a bioluminescence assay with the OmpX-NanoLuc construct. This gave the following results (see Figure 1).

Figure 1: Bioluminescence results of our OmpX-NanoLuc construct.

We've also performed a bioluminescence assay for the construct that both contains OmpX-NanoLuc and OmpX-mNeonGreen. This gave the following results (see Figure 2). From this it can be concluded that both the construct were present, that NanoLuc worked well as a BRET donor and that mNeonGreen worked well as a BRET acceptor.

This part works very well. We used NanoLuc in a BRET sensor, connected to OmpX with a BsoBI-linker. When furimazine is added, NanoLuc will work as a donor, which means that the energy of an electron falling back to its ground state is coupled to a transition of an electron in the RET Acceptor from its ground state to the excited state. We used mNeonGreen as acceptor in this BRET sensor. For more information and further characterization, see the Applications section above.
