Usage and Biology
This composite part is made up with seven basic parts, the His tag, T7 promoter, RBS and our target protein Myxo. It encodes a protein which is Myxo fused with His tag. The fusion protein is about 27.9 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of Myxo . It is convenient for us to purify our target protein.
Molecular cloning
First, we used the vector pGEX-28a 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.
