Usage and Biology=
This composite part is made up with seven basic parts, the His tag, T7 promoter, RBS and our target proteinAFM-1 NDM-23. It encodes a protein which is AFM-1 fused with His tag. The fusion protein is about 28.2 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of AFM-1. It is convenient for us to purify our target protein.
Molecular cloning
First, we used the vector pGEX-6p-1 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.
