Usage and Biology

This composite part is made up with seven basic parts, the His tag, T7 promoter, RBS ,Linker h ,Linker f,T7 terminatorand and our target protein VIM-66. It encodes a protein which is VIM-66 fused with His tag.Linker h is from the vector pET-28a, which connects the RBS to His tag sequence.Linker f from vector pGEX-6p-1, contains the thrombin restriction site and T7 tag. The fusion protein is about 28.3 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of VIM-66 . It is convenient for us to purify our target protein.

Molecular cloning

We insert VIM-66 gene into the standard vector then transfer it into E.coli.
