Usage and Biology
This composite part is made up with six basic parts(Tac promoter，RBS a , Linker g, GST, Linker e and MUS-2). It encodes a protein which is MUS-2 fused with GST tag. The fusion protein is about 54.3 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of MUS-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
We used the vector pGEX-6p-1 to construct our expression plasmid.

After verification, it was determined that the construction is successful.
