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 PEDO-1. It encodes a protein which is PEDO-1 fused with His-Sumo tag. The fusion protein is about 44.2kD. In order to gain the highly purified target protein, we add His-Sumo tag in N-terminal of PEDO-1 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

First, we used the vector pET28b-sumo to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
