Usage and Biology=
This composite part is made up with seven basic parts, the His tag, T7 promoter, RBS and our target protein CPS-1. It encodes a protein which is CPS-1 fused with His tag. The fusion protein is about 33.2 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of CPS-1 . It is convenient for us to purify our target protein.
Molecular cloning
Figure 1. The PCR result of CPS-1.
After verification, it was determined that the construction is successful. We converted the plasmid to E. coli BL21(DE3) for expression and purification.
