Usage and Biology

This composite part is made up with seven basic parts, the His tag, T7 promoter, RBS ，Linker h ，Linker f，T7 terminatorand and our target protein SHD. It encodes a protein which is SHD fused with His tag. Linker h is from the vector pET-28a, which connects the RBS to His tag sequence.Linker f from vector pGEX-6p-1, contains the thrombin restriction site and T7 tag.The fusion protein is about 29.0 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of SHD . It is convenient for us to purify our target protein.

Molecular cloning

First, we used the vector pGEX-28a to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.

After verification, it was determined that the construction is successful. We converted the plasmid to E. coli BL21(DE3) for expression and purification.
