Tac promoter+RBS a+Linker g+GST+Linker e+ARL-1

This part consists of Tac promoter,RBS and protein coding sequence (GST+Linker e+ARL-1),and the biological module can be built into E.coli for protein expression.

Usage and Biology

This composite part is made up with six basic parts(Tac promoter，RBS a , Linker g, GST, Linker e and ARL-1). It encodes a protein which is ARL-1 fused with GST tag. The fusion protein is about 57.0 kD. In order to gain the highly purified target protein, we add GST tag in N-terminal of ARL-1 and combine the two parts with the cutting site of Prescission Protease. The fusion protein can be cut off at the cutting site by Prescission Protease. It is convenient for us to purify our target protein.

Molecular cloning

First, we used the vector pGEX-6p-1 and the vector to construct our expression plasmid. And then we converted the plasmid constructed to E. coli DH5α to expand the plasmid largely.
