Usage and Biology

This composite part is made up with six basic parts(RBS , Linker h, His, Linker f , AFM-1 and T7 terminator ). It encodes a protein which is AFM-1 fused with His tag. The fusion protein is about 28.2 kD. It is convenient for us to purify our target protein.

Molecular cloning

First, we used the vector pET28Ba to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.

After verification, it was determined that the construction is successful. We converted the plasmid to E. coli BL21(DE3) for expression and purification.
