Usage and Biology=

This composite part is made up with three basic parts, the His tag, T7 promoter, RBS and our target protein GIM-2. It encodes a protein which is GIM-2 fused with His tag. The fusion protein is about 27.4 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of GIM-2. It is convenient for us to purify our target protein.
