T7 promoter-RBS(B0034)_kil(Ekil)

Summary

The usage of T7 promoter and RBS is to highly express the Lysis protein for Colicin-E1.

Identification

When we wre building this circuit, we did the nucleic acid gel electrophoresis experiment to verify. After the circuit was built, we sent the plasmid to sequence, and got the correct sequencing. After new molecular cloning experiments, we did Enzyme-Cut identification to certify the plasmid was correct. We used the EcoRI and PstI to cut the plasmid, then we got the target separate fragment-204bp. (Fig.1)

Fig.1 The result of this plasmid cut with enzyme EcoRI and PstI.

The plasmid was transformed into BL21(DE3).After growing the single colonies,SDS-PAGE protein gel electrophoresis was used to certify the expression of Ekil,then we got the target molecular weight-4.8kDa.(Fig.2)

Fig.1 The result of the protein molecular weight.
