Usage and Biology

This composite part is made up with six basic parts(Tac promoter,RBS a , Linker g, GST, Linker e and PEDO-1). It encodes a protein which is PEDO-1 fused with GST tag. The fusion protein is about 58.2 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of PEDO-1 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.
