Usage and Biology
This composite part is made up with three basic parts, the HiS tag, the thrombin restriction site and our target protein Elbla2-1. It encodes a protein which is Elbla2-1 fused with His tag. The fusion protein is about 27.5 kD. It is convenient for us to purify our target protein.
Molecular cloning
First, we used the vector pET28a to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
