This composite part is made up with nine basic parts, T7 promoter, the RBS b， the linker h， His tag，the linker a, Sumo tag, linker b, the gene of Elbla2-1 and T7 terminator.It encodes a protein which is Elbla2-1 fused with His and Sumo tag. The fusion protein is about 39.5 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of Elbla2-1 and combine Sumo tag to increased protein solubility. The fusion protein can be cut off at the cutting site by Prescission Protease. It is convenient for us to purify our target protein.<br>

Usage and Biology

This composite part is made up with nine basic parts, T7 promoter, the RBS b， the linker h， His tag，the linker a, Sumo tag, linker b, the gene of ElblaII and T7 terminator.It encodes a protein which is ElblaII fused with His and Sumo tag. The fusion protein is about 39.5 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of ElblaII and combine Sumo tag to increased protein solubility. The fusion protein can be cut off at the cutting site by Prescission Protease. 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.
