oprF-GS-Sitag-FLAG

The report part of our circuit. It can be expressed to bind silicon

Usage and Biology

oprF is motif cell wall anchor domain protein. GS stands for GS linker. Sitag-FLAG is designed to express specially protein. The genetic engineering bacteria can produce the protein on its membrane. Then the bacteria can be absorbed by silica surface. So we can capture them. Figure 1 shows the circuit of it.

Figure 1: The circuit of oprF-GS-Sitag-FLAG.

As we have said, this part is a final part. After sensing and capture finish, the bacteria will be bound onto silica surface. We can achieve our goal to get them(with lanthanum). Figure 2 shows how it works.

Characterization

We did some experiment to prove it works.

SDS-PAGE

After oprF-GS-Sitag-FLAG is expressed successfully,we centrifuged the bacteria liquid and separated different proteins by SDS-PAGE. As figure 3 shows.
