Usage and Biology
This composite part is made up with three basic parts, the GST tag, the cutting site of Prescission Protease and our target protein GIM-2. It encodes a protein which is GIM-2 fused with GST tag. The fusion protein is about 53.4 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of GIM-2 and combine the two parts with the cutting site of Prescission Protease. 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 pGEX-6p-1 to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
