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 VIM-66.

Usage and Biology

This composite part is made up with five basic parts, the His tag, the Sumo tag, three cutting sites(NdeI, NheI and BamHI) and our target protein VIM-66. It encodes a protein which is VIM-66 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 VIM-66 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 insert VIM-66 gene into the standard vector then transfer it into E.coli.
