Weak T7 promoter - Universal RBS - Φ29 DNAP - T7 terminator

A level 1 construct with a 0.1 T7 p, a universal RBS, DNAP and a T7 terminator.

The construct is confirmed by sequencing and there are no mutations.

Toxicity

Our Sci-Phi 29 tool is based on four components of the Φ29 bacteriophage: DNAP, TP, p5 and p6. However, overexpression of these proteins are toxic for the cell. In order to determine the optimal expression levels of the proteins in live cells, we carried out viability assays in E. coli BL21(DE3) pLysS. The results are shown in the graphs below.
