RBS+Linker h+His+Linker f+TMB-2+T7 terminator

This part consists of RBS, Linker h, protein coding sequence(His+Linker f+TMB-2) and T7 terminator,and the biological module can be build into E.coli for protein expression. This part can be prefaced with promoters of different strengths and types to regulate expression function.

Usage and Biology

This composite part is made up with six basic parts(RBS , Linker h, His, Linker f , TMB-2 and T7 terminator ). It encodes a protein which is TMB-2 fused with His tag. The fusion protein is about 27.2 kD. It is convenient for us to purify our target protein.

Molecular cloning

First, we used the vector pET-28a to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
