Usage and Biology
This composite part is made up with four basic parts, the His tag, the Sumo tag, three cutting sites(NdeI, NheI and BamHI) and our target protein MUS-2. It encodes a protein which is MUS-2 fused with His-Sumo tag. The fusion protein is about 40.3kD. In order to gain the highly purified target protein, we add His-Sumo tag in N-terminal of MUS-2 and combine the three parts with these three cutting sites. The fusion protein can be cut off at the cutting site BamHI. It is convenient for us to purify our target protein.
Molecular cloning
We used the vector pET28-sumo to construct our expression plasmid.

After verification, it was determined that the construction is successful.
