This composite part is made up with seven basic parts, the His tag, T7 promoter, RBS and our target protein BcII-194. It encodes a protein which is BcII-194 fused with His tag. The fusion protein is about 28.1 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of BcII-194.  It is convenient for us to purify our target protein.<br>

Then 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.After verification, it was determined that the construction is successful. We converted the plasmid to ''E. coli'' BL21(DE3) for expression and purification.<br>

T7 promoter+RBS b+Linker h+His+Linker f+BCll-194+T7 terminator

This part consists of T7 promoter, RBS and protein coding sequence（His+Linker f+NDM-23），and the biological module can be built into E.coli for protein expression.

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 BcII-194. It encodes a protein which is BcII-194 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 28.1 kD. In order to gain the highly purified target protein, we add His tag in N-terminal of BcII-194. It is convenient for us to purify our target protein.

Molecular cloning

First,we obtained BcII by PCR.
