Usage and Biology

This composite part is made up with three basic parts, the HiS tag, the thrombin restriction site and our target protein BlaB-14. It encodes a protein which is BlaB-14 fused with His tag. The fusion protein is about 28.3 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.We then extracted plasmids and performed double enzyme digestion verification.
