Usage and Biology

This composite part is made up with six basic parts(Tac promoter，RBS a , Linker g, GST, Linker e and 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.
